Answer:
The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes
During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.
Answer:
A
Explanation:
Individuals are not born immediately able to play the piano. Therefore, piano playing is not an inherited trait. You get good because you practice.
This is in contrast to physical traits like hair color, ability to role your tongue, or genetic diseases. These are not learned at all, instead, they appear regardless of lifestyle.
However, some genes are thought to predispose you to musical talent. Two people could be born with exactly the same genes that make them good at piano. If one practiced for 8 hours every day, then they will be very good. If the other one never practiced, they wont be able to play.
In contrast, one person could have genes that make them great at piano, and one could have genes that make them terrible. Even if they practice the exact same amount, the one with the better-suited genes will likely progress more quickly!
However, the skill is still a learned trait.
Answer:
Biodiversity is a kind of variation of animals, or plant species within a given habitat
Explanation:
Answer:
Proton motive force, compounds such as ATP.
Explanation:
Large amount of proton motive force(PMF),the usable enegy for the cell ,are produced during electron transport chain when high energy compound such as ATP pump hydrogen ions against the concentration gradient.
When the protons are transported against their concentration gradient at that time proton motive force is generated.
PMF generates energy for the synthesis of ATP by the phosphorylation of ADP with inorganic phosphate.
Answer:
The people who agree on xenotransplantation are those who have severe problems such as heart problems and failure of the kidneys. Xenotransplantation, while it is still being experimented with, is a possibly life-saving option for people with these illnesses. Another reason why people agree on Xenotransplantation is that because it could potentially supply us individuals with an unlimited indefinite quantity of things such as cells, tissues, and organs for humans.
