Give the NUMERICAL value to the following question. If a car was traveling 25
m/s and then accelerated at a rate of 5 m/s/s for 3 s, then what was the final
velocity?
Answer:
Given,
initial velocity= 25m/s
acceleration= 5 m/s
time= 3 s
final velocity= ?
We know that,
acceleration= final velocity- initial velocity/ time
or, 5 = final velocity- 25 / 3
or, 5*3 = final velocity- 25
or, 15+ 25= final velocity
Therefore, final velocity is 40 m/s.
A cell sends messages to itself via
A. paracrine signaling
B. autocrine signaling
C. the nervous system
D. the endocrine system
A cell sends messages to itself via autocrine signalling. So the correct option is B.
What is autocrine signalling?The type of cell signalling in which a cell releases a signal from itself and then that signal binds to the same cell. The chemical signal that is released from the cells is known as autocrine agents or autocrine signals.
Autocrine agents are usually hormones or chemical signals. They act as ligands and then bind to the receptors that are present in the cells that have produced them. Such kind of receptors is known as autocrine receptors.
When the autocrine agents bind to the autocrine receptors, autocrine stimulation occurs. This is a chemical reaction that is induced within for the necessary functions that need to happen.
This autocrine signalling is observed at early developmental stages and organ formation happens. These are for pain sensation & inflammation regulation.
Cells infected with viruses also produce autocrine signalling. Autocrine signalling also has an important function in cellular homeostasis. For example, progesterone is important as an autocrine signal molecule in breast cancer.
Therefore, the correct option is B.

Which states would be the most likely to experience the next volcanic eruption AND earthquake in the United States? List at least 3 for each hazard and explain why they might happen there.
Answer:
AlaskaWashingtonHawaiiCaliforniaOregonExplanation:
Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range. Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state. Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.

describes lipids in water
Answer:
Ok
Explanation:
Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped
explain why oxygen and glucose need to be absorbed and waste products need to be removed
Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.
Oxygen is an odor less and colourless gas that is needed by living organisms.
It is absorbed by living organisms because it serves as a source of fuel.
Glucose is a type of carbohydrate called monosaccharide which is gotten from food.
It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.
Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.
If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

Light that Moves and Molds Gels
Pitt research team demonstrates gels that can be moved, controlled by light
PITTSBURGH—Some animals—like the octopus and cuttlefish—transform their shape based on environment, fending off attackers or threats in the wild. For decades, researchers have worked toward mimicking similar biological responses in non-living organisms, as it would have significant implications in the medical arena.
Now, researchers at the University of Pittsburgh have demonstrated such a biomimetic response using hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained motion—a uniquely biomimetic behavior.
Together with Olga Kuksenok, research associate professor in the Swanson School, Balazs experimented with a newer type of hydrogel containing spirobenzopyran molecules. Such materials had been previously shown to form distinct 2-D patterns on initially flat surfaces when introduced to varying displays of light and are hydrophilic in the dark but become hydrophobic under blue light illumination. Therefore, Balazs and Kuksenok anticipated that light could be a useful stimulus for tailoring the gel’s shape.
Using computer modeling, the Pitt team demonstrated that the gels “ran away” when exposed to the light, exhibiting direct, sustained motion. The team also factored in heat—combining the light and local variations in temperature to further control the samples’ motions. Controlling a material with light and temperature could be applicable, Balazs said, in terms of regulating the movement of a microscopic “conveyor belt” or “elevator” in a microfluidic device.

“Imagine an apartment with a particular arrangement of rooms all in one location,” said lead author Anna Balazs, Pitt Distinguished Professor of Chemical and Petroleum Engineering in the Swanson School of Engineering. “Now, consider the possibility of being able to shine a particular configuration of lights on this structure and thereby completely changing not only the entire layout, but also the location of the apartment. This is what we’ve demonstrated with hydrogels.”

Which type of carbohydrate is this?
A) Monosaccharide
B) Simple sugar
C) Complex carbohydrate
D) Disaccharide
Answer:
A
Explanation:
monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.
While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.

c. Dependent Variable:
d. Independent Variable:
3. What type of data do you think John will collect (What will be the results of the experiment)?
4. What conclusions will John be able to make from the results of the experiment?
The answers to the questions required for the design experiment above are :
If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal. The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach. The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low). The Dependent variable : Number of shark attacks The Independent variable : The different number of elephant seals found. Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points. John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.
