Answer:

When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward. This makes the chest cavity bigger and pulls air through the nose or mouth into the lungs.

Answer:

respiratory system

Explanation:

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

In the previous question, you used the Hardy-Weinberg equation to determine the frequencies of the genotypes for HH, Hh, and hh,
Oxana [17]

The expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.

<h3>What is the Hardy-Weinberg equation?</h3>

The hardy-Weinberg equation is a mathematical equation used to calculate the genetic variation of a population at equilibrium.

The given frequencies are HH = 0.04

Hh = 0.32

hh =  0.64

So, the percentages are HH = 4%, Hh = 32%, hh = 64%.

The total percentage will be (4 + 32 + 64 = 100)

The total size is 150

Now,

The number of HH genotype is 0.4 × 150 = 60

The number of Hh genotype is 0.32 × 150 = 48

The number of hh genotype is 0.64 × 150 = 96

The total is 6 + 48 + 96 = 150

Thus, the expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.
