Answer:

B is the correct answer.

Explanation:

The sensory receptors in the nose send signals to the olfactory bulb. These signals are then processed by the brain, which sends a response. Olfactory bulb is the one that receives olfactory(relating to the sense of smell) information which is then relayed to other parts of the brain.

g If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time

Elenna [48]

Answer:

a. 8.1 milligrams

b. 40.07 hours

c. 8.859 milligrams

Explanation:

If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by

$A_{t}=10e^{-0.0173t}$

Where A(t) = amount of Valium remaining in the blood after t hours

t = time or duration after the drug is taken

a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours

$A_{12}=10e^{-0.0173\times12}$

$A_{12}=10e^{-0.2076}$

= 10×0.81253

= 8.1 milligrams

b. In this part we have to calculate the time when A(t) = 5 milligrams

$5=10e^{-0.0173\timest}$

$\frac{5}{10}=e^{-0.0173t}$

0.5 = $e^{-0.0173t}$

Now we take natural log on both the sides of the equation.

ln(0.5) = ln( $e^{-0.0173t})$

-0.69314 = -0.0173t

t = $\frac{0.69314}{0.0173}$

t = 40.0658

≈ 40.07 hours

c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.

$A_{7}=10e^{-0.0173\times7}$

$A_{7}=10e^{-0.1211}$

= 10×0.8859

= 8.859 milligrams

Which of the following best describes the relationship between the structure of the cell membrane and it's function

Sergeeva-Olga [200]

The cell membrane folds upon itself easily, which facilitates cellular reproduction by mitosis.

The membrane is a flexible, fluid mosaic and changes shape easily to create holes for substances to move in and out of the cell. 

The outer layer of the membrane is hydrophilic, which allows water to flow in and out of the cell easily to eliminate waste. 

The proteins that are embedded in the cell membrane act as channels to transport substances in and out of the cell.

Which best explains how the body mantens homeostats)

jek_recluse [69]

Answer:

All systems work together to stabilize the body.

Explanation:

Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.

Identify how a hormone molecule performs its function. formation of mRNA in the nucleus initiation of DNA replication because of

expeople1 [14]

Answer:

binding of the hormone molecule with its receptor of the cell.

Explanation:

Hormones are chemical messengers secreted or released by endocrine glands to effect a response in another location called target location. Hormones are proteinous molecules and like every other protein, its function is determined by its shape.

Hormones function or effect their changes by binding to the receptor of the target cell. The hormone recognizes and will only bind to its own receptor molecule on its target cell on order to bring about any change. This defines the specificity of the hormone.
