Answer:
a The pulmonary artery carries deoxygenated blood.
Explanation:
This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria to the pulmonary circulation. That is to the lungs for the exchange of the C02 in the deoxygenated blood with oxygen in the lungs.
The blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.
From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the systemic circulation.
Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries because of convey of blood away from the heart,a typical role of arteries
Answer:
Prophase, metaphase, anaphase, telophase
Explanation:
Answer:
The answer is 16.
Explanation:
Somatic cells include all the cells in the body except for the reproductive cells. Haploid cells are used to represent the reproductive cells which have half the chromosome as the somatic cells. So if there are 32 sister chromatids in a somatic cell, which means there are 16 chromosomes, then the haploid number for it is 16 chromatids. I hope this answer helps.
