Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.

Consider a mixture of bacterial species from the same genus, such as Staphylococcus. Some members of this genus are harmful pathogens, while others are not. Would a selective medium alone be a good tool to separate the harmful species from the non-harmful species
Answer:
No. There are different types of media that may result useful to separate this species. Moreover, differential media can also be used to differentiate closely related species (e.g., by the change of color in the medium)
Explanation:
A selective media is a type of media capable of selecting for the growth of specific microorganisms while inhibiting the growth of others. For example, if a bacterium is resistant to an antibiotic (e.g., ampicillin), then this compound can be added to the medium in order to select bacteria that are resistant and simultaneously inhibit the growth of susceptible bacteria. Moreover, a differential media is a media that contain chemical indicators that allow certain microorganisms to be visually identified by the appearance of the colony and/or its surrounding media. Differential media have into account certain biochemical characteristics of target microorganisms (e.g., the change of color in the medium which is associated with the ability of the microorganism to ferment sugar molecules).

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?
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.

heyy mate! hope this helped you!
A survivorship curve is a graph that shows the proportion of individuals in a population surviving at different age intervals. The correct statement is that survivorship curve describes the pattern of mortality in a population over time. The correct option is C.
What is Survivorship curve?Survivorship curve describes the pattern of mortality in a population over time. The survivorship curve is divided into three types, i.e., Type 1, Type 2, and Type 3. Survivorship curve type 1 represents a high survival rate throughout the lifespan of the population. It shows that most individuals survive until old age, and the mortality rate increases at the end of the lifespan.
Survivorship curve type 2 shows a relatively constant rate of mortality throughout the lifespan of the population. It indicates that the probability of survival remains the same throughout life.
Survivorship curve type 3 represents high mortality rates among young individuals in a population. It shows that most individuals die young, and only a few individuals survive to adulthood.
Therefore, the correct option is C.

As you completed this assignment and reviewed the lectures (see the socioecological model lecture and diagram provided), you realized that there are several factors that influenced your own daily food choices. What are they? Explain. Think about the following as you write your response: (essay format for each segment)
1. Individual factors influencing your daily food choices (demographics, other personal factors)
2. Settings (homes, schools, worksites, etc.)
3. Sectors (systems, organizations, and businesses and industries), and
4. Social and cultural norms and values (belief systems, traditions, heritage, etc.).
Additional question: how can the Social-Ecological Model help us with our daily food choices?
Answer:
factors that influenced daily food choices:
biological determinantseconomical determinantsphysiological determinantsphysical determinantssocial determinantsbehavioral determinantsExplanation:
Social -ecological system is the set of different factors which influence our living styles, our dietary habits, our dress choice etc. on a daily basis. In today's world, everything act is done by people are only based on its popularity or followed by trends. Similarly, our daily food choices are also influenced by the trends and our surroundings in which we live. There is the impact of multiple factors on our daily food choices.
Behavioral factors: behavioral factor is the most important factor which have a huge impact on our daily food choice. An individual health condition, behavior, attitude, work routine majorly influence the food choices. An individual personal preferences, likes and dislikes also influenced his food choices.Biological factors: these factors can influence individually as well as globally. Hunger, nutrient requirements, condition of safe food, health conditions are the major biological factors which play major role, when it comes to choose daily food. These factors can affect the global food preferences, for example in the pandemic of convid-19 food choice were similar of every individual globally. Economic factors: availability of food, cost of food, balancing of needs and demands also impacts our daily food choices. If cost are too high of basic food and the availability is only limited to certain people, it automatically impacts on the food choice of an individual. Social Factor: when we talk about social factors these are the group of different small factors like culture, work environment, school, colleges, religious preferences, friends circles, demographic conditions etc. our daily food choices are mostly based on the social factors because our likes and dislikes, meal patterns, our preference of food (cooked, raw, packages, cooking style etc.) Everything based on the impact of the surroundings. In schools and colleges, students are bound to eat what is available or what their friends prefer to eat. Religious backgrounds always choose as per their rulings. Traditional foods, cultural heritages also an impactful factor for our daily food choices.Physiological factors: mental health condition are also one of the important factor which can not be neglected when we choose our food to eat. A healthy individuals preferences will always be different from a sick person.Social-ecological model can help us with our daily food choices by giving us the knowledge of the factors and its healthy impact on our food choices which can lead us to a healthy life and prosperous environment. Smart choice not only make us health but also make the environment healthy for our lives.

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
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.

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.
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.

One of your classmates submits the post below which is a very informative post about criteria for safe food production during the manufacturing process. What is missing from this post? "I recently read that industrial food processing factories are required to undergo periodic inspections by the United States Department of Agriculture as well as by the Food and Drug Administration. For the USDA, these inspections are conducted by staff in the Food Safety and Inspection Service, or FSIS."A. Did not refer to the source of the information in the body of the postB. Did not state what s/he specifically learned from the sourceC. Did not provide a citation for the source of the information
Answer:
A. Did not refer to the source of the information in the body of the post
Explanation:
In the post written by his friend, we can see that he decided to write information about the periodic inspections carried out by the United States Department of Agriculture as well as by the Food and Drug Administration, because he read about these inspections somewhere. However, he forgot to show this place where he read this information, that is, he forgot to present the source where he got the information presented in the post. By presenting the source, it would make the post more trustworthy and relevant.

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
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.
Watch this video about a river that China is building. Explain how the river will help prevent the negative effects of drought. In your answer, explain any negative effects that you foresee this new river will have on the people or on natural habitats.
Answer: The river will increase Beijing’s water supply, which is currently at risk of not meeting the city’s needs. This increase will help to soften the effect of droughts.
The downside of the new river is that it may disrupt natural areas, including habitats for plants and animals. The project will also be expensive and may take up space that could be used for homes, businesses, or agriculture.
Explanation: Change the wording...
The construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs, and one way that a new river can help prevent the negative effects of drought is by increasing the recharge of groundwater resources.
What is a drought?During periods of drought, water resources can become scarce, leading to reduced crop yields, drinking water shortages, and negative impacts on ecosystems. By providing a new source of water, a new river can help alleviate some of these negative effects. A new river can provide a source of water that can help recharge aquifers and replenish groundwater supplies. However, the construction of a new river can also have negative effects on people and natural habitats. One potential negative impact is the displacement of people living in the area where the river is being constructed. This can lead to the loss of homes, farms, and livelihoods for local communities.
Hence, the construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs.
