In fetal circulation, the ductus venosus bypasses the liver and the ductus arteriousus bypasses the lungs. Ductus arteriosus also called ductus botalli is a blood vessel connecting the main pulmonary artery to the proximal ascending aorta. It does allow most of the blood from right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Ductus venosus on the hand allows oxygenated blood from the placenta to bypass the liver.
Answer:
d. if my hypothesis is correct, I can expect certain test results
Explanation:
To create a theory is not enough to state an assumption. Called scientific research, the practice tries, through a logical procedure, to produce tested, proven and safe scientific knowledge. This concept is based on the logic of scientific research that states that a hypothesis must be tested, because if the hypothesis is correct, certain test results can be expected. For this, some rules or phases are part of the process. And they are: observation, hypotheses, research method and conclusion.
Thus, we can conclude that among the alternatives presented, the one that best describes the logic of scientific investigation is the letter D.
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
Answer:
The correct answer is - Pons.
Explanation:
The pons is located t below the midbrain and below the midbrain. It is a group of nerves that function as a connection between the cerebrum and cerebellum.
It is related to the various functions of the body such as sleeping, respiration, swallowing, bladder control, hearing, and many more. These functions
