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.
Answer:
Testosterone
Explanation:
This mostly happens at puberty, the LH production rises sharply that ultimtely increases the production of Testosterone by Leydig cells of testes. The secondary sexual characteristics start to appear by this sharp rise in testosterone levels.
A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. ... In humans, it takes about four days for a zygote to become a morula and another three days until the embryo attaches itself to the mother's uterine wall.
Answer:
2
Explanation:
The bones in the forelimbs of penguins and seals are best described as analogous, while the flippers of penguins and seals are homologous.
Analogous structures are structures that are similar in different organisms, even though they are unrelated to each other. For instance, the wings of birds and the fins of a penguin or a fish.
Homologous structures are similar structures in related organisms. Both the penguins and the seals have flippers. Another example is the human arm and the wings of a bat. Both have similar structures internally, but while a human lifts items with their hands, the birds use theirs for flying.
