The linear regression equation shows that the base metabolic rate of a human of 40.57 kilograms is likely to be 9.557.

It should be noted that regression simply means a set of statistical process that is used for the estimation of the relationship between the dependent variable and the independent variable. In the linear regression, it should be noted that the slope is the a that van be seen on the linear equation y = a + bx.

Based on the information given, it should be noted that for the human with a metabolic rate of 40.57 kilograms, the natural log will simply be:

x = In(40.57)

x = 1.6082

Therefore, the natural log for the metabolism rate will be:

Y = a + bx

Y = 1.0648 + (0.74148x)

Y = 1.0648 + (0.74148 × 1.6082)

Y = 1.0648 + 1.1925

Y = 2.2573

Then, we'll then take the inverse log of the above value which will be 9.557.

The responses observed in type IV hypersensitivities result from the action of T cells and phagocytes.

Hypersensitivity IV type, also called delayed-type hypersensitivity (DTH), involves T cell-antigen interactions that cause activation and secretion of cytokines. This type of hypersensitivity requires sensitized lymphocytes that respond 24–48 hours after exposure to soluble antigens. A type IV hypersensitivity reaction is a cell-mediated reaction that can occur in response to contact with certain allergens, resulting in what is called contact dermatitis, or in response to certain diagnostic procedures such as the tuberculin skin test. Certain allergens need to be avoided to treat this condition. Type IV hypersensitivity response is observed results from the action of T cells and macrophages while other types are mediated by antibodies. This reaction  occurs at least 1–3 days after the initial exposure. Type IV hypersensitivity is the mechanism of many autoimmune disorders.

ATP production depends only on intensity of light and not on wavelength of light.

The production of plant food, the size and color of leaves, and flowering are all impacted by light intensity. Plants that are grown in low light typically have spindly growth and leaves that are light green. Similar plants cultivated under intense lighting typically have shorter, better branches and larger, dark green leaves.

Lack of light causes the plants' leaves to yellow, their stems to weaken, and their leaves to shrink. Lack of light causes plants to eventually lose their color and perish. The growth of plants can potentially be harmed by excessive light exposure. One of the many elements influencing plant growth is light.

The main benefit of storing glucose in a cell as a polysaccharide (e.g., glycogen) instead of as free glucose is that polysaccharide take up less physical space. The polysaccharide is less susceptible to undesired oxidation.

Glucose molecules are soluble in water and thus can cause the cell to become hypertonic.

This will result in the entry of water molecules within the cells and cause it to lyse.

On the other hand, glycogen is insoluble in water and therefore stays inert. It does not cause any imbalance in osmotic pressure.

If a container is divided into two compartments by membrane, both compartments are filled with a solution A an B having similar solute concentration, and a solution B is having higher volume. As the solutions are of same concentration there is no osmosis between two solutions separated by a semipermeable membrane, they are said to be isotonic.

In this situation, water can freely pass the membrane without affecting the solute concentration on either side. Thus over a time both solution A and B will have no change in solute concentration and the level of solution B will be equilibrated with solution A.

In plant cells grown in the presence of a metabolic poison that specifically inhibits mitochondrial F1ATP synthase, one would expect: An increase in the pH difference across the inner mitochondrial membrane.

The electron transport chain can no longer pump electrons into the intermembrane space. The pH of the intermembrane space would increase, lowering the pH gradient and stopping ATP synthesis. The function of ATP synthase is to form ATP from ADP and inorganic phosphate (Pi) in the F1 sector. This is possible due to the energy derived from the gradient of protons that cross the inner mitochondrial membrane from the intermembrane space into the matrix via the Fo part of the enzyme.

Autotroph

An organism that uses organic carbon for its carbon needs and sunlight for its energy needs would be called an autotroph.

An organism that has the ability to make its own food from inorganic materials is known as an autotroph. Contrarily, heterotrophs are organisms that are dependent on the eating of other species for their survival because they are unable to manufacture their own nutrients. Because they frequently provide food for heterotrophs, autotrophs are crucial producers in the ecosystem.

The most prevalent kinds of autotrophs are plants, which make their own food through the process of photosynthesis. In order to create nutrition from light, plants contain a specialized organelle called a chloroplast within their cells. These organelles generate glucose, a basic sugar needed for energy, as well as oxygen as a byproduct when combined with water and carbon dioxide. In addition to providing nutrients for the producing plant, glucose also serves as an energy source for the plants' consumers. Algae, plankton, and some varieties of bacteria are additional examples of autotrophs that engage in photosynthesis.
