Heat Transfer Mechanisms 1.In your own words, using the pennies activity, define the three different heat transfer mechanisms. Your definitions should include:
(i) information about how energy is moving
(ii) what is happening microscopically (that is, at the atomic level)
(iii) what phase(s) of materials is usually involved.
Answers
Answer:
The three modes of heat transfer are: 1) Radiation 2) Convection 3) Conduction
Explanation:
RADIATION:
It is the mode of heat transfer which requires no medium because the transfer of energy takes place in the form of electromagnetic radiations. The spectrum of radiations that contribute to the heat transfer via radiation is the wavelength ranging from 0.1 μm to 100 μm.
For example the heat from the sun reaches the earth via radiation that passes through space and then through the atmosphere of the earth.
CONVECTION:
It is the mode of heat transfer that takes place in a fluid matter. The molecules in this case move from one place to another due to the difference in density developed as a result of heat absorption.
Example, the boiling of water. When the water in a utensil is heated, the heat is supplied at the bottom. In such a case the molecules of the water absorb the heat resulting in increased intermolecular spacing and hence the water at the bottom becomes the least dense in the bulk of water mass in the utensil hence rises up at to the free surface of the fluid mass. Then the densest mass of the fluid occupies the bottom space and is heated by the heat source supplied. This chain continues.
CONDUCTION:
This is the process of heat transfer from one molecule to the next neighbouring molecules. The propagation of heat energy occurs in a sequential manner starting from the molecule nearest to the heat source. The microscopic phenomenon happens in the form of lattice vibrations that are responsible for the transfer of heat energy via conduction.
Example, while heating of a pan the base heats up at first being continuously exposed to heat whereas the handle of the pan being far away from the source heats up after a long time.

What processes found at a divergent boundary will help form the following rocks?
Answers
Answer:
B
Explanation:
What is a divergent boundary:
In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates moving away from each other.
They can produce rifts, which become rift valleys.
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that magma rises to fill.
Sedimentary rocks form due to deposition, and accumulation
Metamorphic rocks form in a transformation of existing rock to new rock in a process called metamorphism.
Igneous rocks form through the cooling and solidification of magma or lava.
When the filled gaps of magma cool off, it will produce igneous rocks.

Which of the following is a skin sensory receptor for touch?
A) Pacinian corpuscle
B) Meissner's corpuscle
C) Ruffini body
D) free nerve ending
Answers
Meissner's corpuscle is a skin sensory receptor for touch.
Meissner corpuscles are responsible for the sense of touch or light pressure, that is, they are very sensitive to the movement of objects on the skin and to very low vibrations.
About Meissner corpuscles:
• They are located on the lips and fingertips and are very sensitive.
• Meissner corpuscles act when there is a soft and light touch, and when vibrations are less than 50 hertz.
• These receptors can be altered when there is the presence of diseases where both thermal and tactile sensitivity are altered.
Therefore, we can conclude that Meissner corpuscles detect fine touch, that is, they are receptors on the skin that are sensitive to low-frequency vibration.

I will give brainly if your argument is convencing
Answers
Answer:
ok so like i think they do but it also makes things really complicated
Explanation:
becauuuuseeeee its the fact that for me i always think that maybe thats how the world birthed orrrrrrrr that all of this is a made up concept of life cause everything you think about is just another concept. anddddd it could just be like the matrix and its like hard to think about how everything we know couldd just be made up or pointless to the point where there is a point of living ykkkkk.
My argument runs like this. I’ll construe “science” as the set of tools we use to find truth about the universe, with the understanding that these truths are provisional rather than absolute. These tools include observing nature, framing and testing hypotheses, trying your hardest to prove that your hypothesis is wrong to test your confidence that it’s right, doing experiments and above all replicating your and others’ results to increase confidence in your inference.
And I’ll define religion as does philosopher Daniel Dennett: “Social systems whose participants avow belief in a supernatural agent or agents whose approval is to be sought.” Of course many religions don’t fit that definition, but the ones whose compatibility with science is touted most often – the Abrahamic faiths of Judaism, Christianity and Islam – fill the bill.
Next, realize that both religion and science rest on “truth statements” about the universe – claims about reality. The edifice of religion differs from science by additionally dealing with morality, purpose and meaning, but even those areas rest on a foundation of empirical claims. You can hardly call yourself a Christian if you don’t believe in the Resurrection of Christ, a Muslim if you don’t believe the angel Gabriel dictated the Qur’an to Muhammad, or a Mormon if you don’t believe that the angel Moroni showed Joseph Smith the golden plates that became the Book of Mormon. After all, why accept a faith’s authoritative teachings if you reject its truth claims?
Indeed, even the Bible notes this: “But if there be no resurrection of the dead, then is Christ not risen: And if Christ be not risen, then is our preaching vain, and your faith is also vain.”
Many theologians emphasize religion’s empirical foundations, agreeing with the physicist and Anglican priest John Polkinghorne:
“The question of truth is as central to [religion’s] concern as it is in science. Religious belief can guide one in life or strengthen one at the approach of death, but unless it is actually true it can do neither of these things and so would amount to no more than an illusory exercise in comforting fantasy.”
The conflict between science and faith, then, rests on the methods they use to decide what is true, and what truths result: These are conflicts of both methodology and outcome.
In contrast to the methods of science, religion adjudicates truth not empirically, but via dogma, scripture and authority – in other words, through faith, defined in Hebrews 11 as “the substance of things hoped for, the evidence of things not seen.” In science, faith without evidence is a vice, while in religion it’s a virtue. Recall what Jesus said to “doubting Thomas,” who insisted in poking his fingers into the resurrected Savior’s wounds: “Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.”
Two ways to look at the same thing, never the twain shall meet. Gabriel Lamza/Unsplash
And yet, without supporting evidence, Americans believe a number of religious claims: 74 percent of us believe in God, 68 percent in the divinity of Jesus, 68 percent in Heaven, 57 percent in the virgin birth, and 58 percent in the Devil and Hell. Why do they think these are true? Faith.
But different religions make different – and often conflicting – claims, and there’s no way to judge which claims are right. There are over 4,000 religions on this planet, and their “truths” are quite different. (Muslims and Jews, for instance, absolutely reject the Christian belief that Jesus was the son of God.) Indeed, new sects often arise when some believers reject what others see as true. Lutherans split over the truth of evolution, while Unitarians rejected other Protestants’ belief that Jesus was part of God.
And while science has had success after success in understanding the universe, the “method” of using faith has led to no proof of the divine. How many gods are there? What are their natures and moral creeds? Is there an afterlife? Why is there moral and physical evil? There is no one answer to any of these questions. All is mystery, for all rests on faith.
The “war” between science and religion, then, is a conflict about whether you have good reasons for believing what you do: whether you see faith as a vice or a virtue.
Compartmentalizing realms is irrational
So how do the faithful reconcile science and religion? Often they point to the existence of religious scientists, like NIH Director Francis Collins, or to the many religious people who accept science. But I’d argue that this is compartmentalization, not compatibility, for how can you reject the divine in your laboratory but accept that the wine you sip on Sunday is the blood of Jesus?

Melanie has had a recent cold with symptoms of runny nose, sneezing, coughing, congestion, and malaise. Today, she is concerned that she has a sharp pain in her chest. She goes to see her health care provider, and is diagnosed with costochondritis, an inflammation in the cartilage between the ribs. From your reading related to cellular injury and adaptations as well as inflammation, answer the following questions:
a. What anatomic problem most likely leads to costochondritis?
b. What is the injury in costochondritis?
c. What would the acute inflammatory response look like?
Answers
Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.

An environmental microbiologist collects a water sample that contains bacteria that have not contacted the outside world for thousands of years. He uses sterile technique while transporting then back to the lab for testing. To his surprise, they are resistant to ampicillin. Based on your knowledge of bacterial evolution, which of the following statements provides the most reasonable explanation for this discovery?
a. The bacteria are a result of contamination on the way to the lab.
b. The bacteria do not contain 50S ribosomal subunits.
c. Vancomycin is a naturally occurring mineral occuring in the cave water.
d. The bacteria randomly acquired a mutation in their cell wall building machinery.
Answers
Answer:
The answer is "Option d".
Explanation:
These genetic mutations in heritage in the genome of the bacterium were referred to as biofilm formation. All those other changes are attributable to some genetic changes during replication. The short term of bacteria and vast quantities of the colony can develop rapidly.
The type of environmental choice then transfers into another generation. Some translations benefit human people and enhance their fitness.
The most logical cause for this finding is Option "D", and although types of bacteria have not been in contact with the outside world for hundreds of years, certain random changes resist penicillin.

Evaluation is the process in any experiment that helps in improving the analysis and remove missing components and errors to get better results. It also checks if all the process is included and running properly without error.
One should constantly be evaluating his or her experiment. It includes assessing how the experiment is going as you carry it out, what could have been improved if it was to be carried out again and how can eliminate any erros.
A researcher wanted to create a loss of function mutation for studying Type I Diabetes in a model animal. What mutation would mimic Type I diabetes?
a) Inhibition of sugar absorption in the small intestine
b) Inhibition of pancreatic beta-cells
c) Up regulation of insulin receptors on the pancreas
d) Down regulation of GLUT4 transporters in muscles
Answers
Answer:
The correct answer is: b) Inhibition of pancreatic beta-cells.
Explanation:
Type 1 Diabetes is a form of Diabetes Mellitus, a condition characterized by chronic hyperglycemia (high blood sugar levels) that can compromise many organs and even cause death if not treated properly.
The most common form of Diabetes Mellitus is Type 2 Diabetes, in which the pancreas produces insulin but cannot reach the target organs because of a pathologic state called Insulin Resistance.
Type 1 Diabetes, instead, is present in patients that cannot produce insulin on their own. Insulin is the most important hormone in the regulation of blood sugar - it is secreted by the pancreatic beta-cells when glycemia rises (which is normal after eating) and it is key in allowing glucose to reach the tissues where it's needed for energy requirements. Type 1 Diabetes is usually diagnosed in young, even pediatric, patients - the pancreatic beta-cells in these individuals are destroyed and unable to function (the reason for this is not clear in all cases), so they have to be administered with exogenous insulin to survive.
For the model animal to better represent Type 1 Diabetes, the mutation would have to inhibit pancreatic beta-cells.

- An organism's gut microbiota is the collection of all the microorganisms (e.g. bacteria, phages, fungi) that live inside the digestive system of that individual.
- A gap junction is a type of intercellular protein connection between animal cells that prevents leakage of materials through the space between the cells.
- The transmembrane protein occludin is one of the component proteins of a tight junction.
- Germ-free mice lack all microorganisms in their digestive systems, a state achieved by delivering them through cesarean section and raising them in sterile incubators.
- Pathogen-free mice are raised under sterile conditions to limit their exposure disease-causing microorganisms.
Explanation:
The blood-brain barrier is a layer of cells made up of endothelial cells that act to limit the passage of substances from the bloodstream in a more selective manner than endothelial cells of capillaries located in other parts of the body. Gut microbiota can be defined as all the microorganisms (i.e., bacteria) inhabiting the mammalian gastrointestinal tract, which helps to ferment non-digestible substrates (e.g., dietary fibers). A gap junction is a class of cell junction that is formed between cells contacting each other which allows small molecules (e.g., water, ions, metabolites, microRNA sequences, etc) to pass through this intercellular communication. In vertebrate animals, cell junctions can be divided into 1-gap junctions (communication between cells), 2-tight junctions (occludin junctions), and 3-adherens junctions, hemidesmosomes and desmosomes (anchor junctions). Tight Junctions are composed of multiple proteins including transmembrane proteins such as occludin, tricellulin, junctional adhesion molecule (JAM), and one member of the claudin protein family. Germfree animals are research animals that have no microorganisms living in or on them, which are housed in controlled/isolated conditions to prevent any type of contamination. Finally, pathogen-free animals are research animals that are guaranteed to be free of particular pathogenic (harmful) microorganisms.
