The answer is B.
Which is “When the air is in the respiratory
medium, there is a greater risk that the tracheal tubes will collapse. The
cartilage in the respiratory system gives support
to the tubes against negative or positive
pressure, during respiration, hence keep
it open.
Answer:Hemopure is a blood substitute developed by Biopure Corporation. *consists of hemoglobin, purified from bovine blood, free in the plasma. *binds oxygen in the lungs then delivers oxygen to the body. *cell-free hemoglobin releases the oxygen more quickly than red blood cells. *risk of high blood pressure and heart attacks.
Explanation:
This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents: AA x OO
Offspring: AO AO AO AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.
Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO. Let's take a look at that crossing:
Parents: AO x OO
Offspring: AO AO OO OO
Thus, in this case, daughter can have genotype OO and blood group O.
Antidiuretic hormone (ADH)
acts on the vascular system and the urinary system to regulate solute-water
content in the body. During dehydration, secreted by the posterior pituitary
gland, the hormone promotes reabsorption of water from urine in the renal
tubules hence decreasing plasma osmolarity.
