Answer: X
Explanation:
Because we see 2 X's in the karyotype, that means that this person can only give an X to their son, who is XY.
Answer:
The correct answer is option (B) "The concentration of ATP in cells is generally much lower than that of AMP".
Explanation:
Adenosine triphosphate (ATP) is the molecule that carries the energy of the cell, allowing it to perform almost every reaction needed to growth, maintain and reproduce. Being an essential molecule in a lot of processes, the amount of ATP in the cell is abundant. The typical intracellular concentration of ATP is around 1–10 mM. While ATP is dephosphorylated during aerobic metabolism to ADP and AMP, usually the concentration of ATP in comparison to ADP and AMP is above 10:1.
<u>Answer:</u>
Comparing and contrasting embryos of different species is called Comparative embryology.
<u>Explanation:</u>
It is the branch of embryology where embryos of different specie are compared to find out that how two special are evolutionary similar or different from each other. It also helps in the identification of organism's closest ancestor. For example: When Aristotle observed embryos of different animal specie, he described that egg laying (oviparous) organisms are different from birth giving (viviparous) organisms. This has a connection with organism's developmental pattern which tell that both organisms have different or common ancestry.

Gene regulation is necessary in the development of multi-cellular organisms because it is necessary to make sure certain things go where they are needed to go. Multi-cellular organisms have more organ systems, therefore depend on more cells to live. Cells have a memory; the genes a cell expresses and the way it behaves depend on the cell's past, as well as its present environment.
I’m pretty sure it’s C. But at the same time it can be A.
