Independent: The second group is not given the drug.
Dependent: Dr. Smith wants to examine weather a new drug increases the maze running performance of older rats.
Constants: Dr. Smith teaches two groups of older rats to find a piece of tasty rat chow in the maze.
Riparian zones are attractive to livestock because they contain lush vegetation that livestock like to eat.
Riparian zones are the transitional areas between land and a water body such as rivers, streams, or lakes. Riparian zones are attractive to livestock because they contain lush vegetation; a vegetation that has a greater variety of plant species. Shrubs such as willows, herbaceous and aquatic plants, such as rushes and sedges, and trees can be found in riparian zones.
Cytokine release syndrome might lead to the dysfunction of multiple organs. It is widely seen in Covi-19 patients.
<u>Explanation:</u>
Cytokine release syndrome arises when cytokines are released in a large number in our blood. This release takes place from our immune system. Cytokines are secreted by one cell and affect other cells. It causes inflamation.
In the case of Covi-19 it has been observed that Cytokine release syndrome plays a major role in affecting our immunity. So it is of utmost importance to study CRS in such patients. Cytokine release syndrome develops mostly after a viral infection in the body.
Answer:
Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.
Answer: High Specific Heat Of Water
Explanation:
Water’s high specific heat helps to maintain low temperature and protects fish life. This is due to the presence of hydrogen bonds in larger amount between water molecules. Of course, specific heat plays a role to capture more energy without rise in temperature.
When heat gets absorbed, water molecules move freely and hydrogen bond gets broken. If temperature decreases, release energy by forming hydrogen bond. Hence, it clearly shows that this water property can drastically change the temperature quickly which is important in protecting a fish in a shallow pond on a hot summer day.
