What is the fastest way to administer nicotine to the brain?
Agata [3.3K]

Answer:

d. Smoking

Explanation:

Nicotine is a chemical found in many plants such as tobacco. It is one of the 4000 chemicals that tobacco presents and the main component that acts in the brain.

This chemical is absorbed through the skin and lining of the mucosa of the nose and mouth, or in the lungs by prior inhalation. Nicotine can quickly reach the bloodstream and brain and reach maximum levels. The action of smoking cigarettes causes nicotine to reach the brain in just 10 seconds after inhalation. Although the acute effects dissipate in a few minutes, they cause the need to continue the intake of the substance (addiction)

A population of horses has individuals that are either gray or chestnut colored. The gray color allele, G, is dominant over the
Dahasolnce [82]

We solve the problem using the Hardy-Wineberg equation.

We have the frequency for gray trait as p =  = 0.8

∴ p² = 0.64

64 % of the horses are homozygous for the gray trait.

Solving for the frequency of white chestnut trait by using the fact that,

p + q = 1

∴ q = 1 - p = 1 - 0.8 = 0.2

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous gray trait,

∴ 2pq = 2 x 0.8 x 0.2 = 0.32

Therefore, in a population of 100 horses, 32% are heterozygous for gray trait.

Hence the total number of gray horses in a population of 100 will be,

32 (heterozygous gray horses) + 64 (homozygous gray horses) = 96 (gray horses)

Hence, 96% of the horses are gray in color.
