The answer is c. A virus is a piece of nucleic acid enclosed in a capsid.

This would actually be known to originate in the "nucleic acid". This would have nothing to do with the DNA it's self, and also protein has nothing to do with it also.Nucleic Acid would be small particals in the cells that would consists of molecules would some sort of chain which would then lead to the DNA, but it would actually have not resemblance of the nucleic acid at any point.

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

Meristematic cells called the _____ add width to the plant body.

bulgar [2K]

vascular cambium


Apical Meristems are found in the tips of the roots and in the buds of the shoots. They supply cells for the plants to grow in length.

Apical Meristems are found in herbaceous plants, woody plants, grasses, and flowering plants.

In flowering plants, shoot apical meristem develops into an inflorescence meristem which produces the floral meristem. The floral meristem is responsible for the production of the sepals, petals, stamens, and carpels of the flower.
