Spermatogenesis produces<span> four </span>gametes<span>, while </span>oogenesis produces one with two to three polar bodies left over. because oocytes contain not only genetic material but also mitochondria.
I think the answer is false!
False, the arrow for C is pointing to the genetic material of the virus cell. The capsid (protein shell) is A.
The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.
Explanation:
The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.
The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.
Both these venous systems (superior and inferior) fill the right atrium.
The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.
The right atrium is filled with blood during diastole.
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.
