The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.
Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
The correct answer is phosphorous but occurs in the form of a phosphate. ATP stands for Adenosine Triphosphate.
ATP is composed of three components. At the center of the molecule is found ribose, a sugar molecule which is the very same sugar that forms part of RNA. To one side of ribose is attached a base known as adenine. This base belongs to a group of molecules made of linked rings of both carbon and nitrogen atoms.
To the other side of ribose is attached a string of phosphate groups which are key to the energy carrying activities of ATP.

Answer:
Degenerate.
Explanation:
The genetic code has following properties -
- It is a triplet codon.
- It is non-overlapping.
- It is comma-less.
- It is non-ambiguous.
- It is degenerate.
- It has stop and start codons.
Out of these properties the Property of Degeneracy has been used in the situation mentioned in the question. Due to degeneracy of the genetic code, more than one codons can code for a single amino acid. Property of degeneracy in the code minimizes the mutational lethality.
