In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.
The producer would be
A) flower
Answer:
The heart is made up of heart muscle known as Cardiac muscle, or myocardium This contracts almost 70 times a minute and pumps about 5 liters of blood each minute.
Explanation:
Horizontal and vertical Speed are indirect towards each other and therefore the earth moves. This causes it to be in constant new positions, causing seasons.
Answer:
Option C, Parasympathetic nervous system stimulation resulting in airway constriction
Explanation:
Complete Question
When a client with a history of asthma takes a walk outside on a windy day with high pollen counts, she may experience an asthma attack, resulting in an increase in respiration rate and wheezing. The body's response is likely related to which pathophysiological principle?
Select one:
a. Influx of macrophages to wall of the pollen, thereby stopping the attack
b. Release of catecholamines causing blood vessel constriction
c. Parasympathetic nervous system stimulation resulting in airway constriction
d. Inhibition of glandular secretions, which causes build up of mucus in the lungs
Solution
The parasympathetic nervous system consists of cranial and sacral spinal nerves. It is responsible for doing the work of sympathetic system thereby decreasing the rate of respiration and heart. During windy climate when pollen grains are in excess, the rate of respiration needs to be higher in order to get sufficient supply of oxygen. But due to activation of parasympathetic nervous system the body tries to preserve its energy by decreasing the rate of various bodily functions and
Hence, option C is correct
