Answer:
D. Both store energy used by the organism.
Explanation:
Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.
Answer:
The correct answer is c It would prevent the receptor from becoming activated.
Explanation:
Mutation in the receptor kinases that leads to cancer allow the dimerization and activation of receptor even in the absence of signalling molecule that means activation of receptor in case of mutant does not requires the presence of Signalling molecule.
That means if the antibody prevents the dimerization of the receptor of the mutant then it(antibody) have to prevent the receptor from being activated.
Answer:
A
Explanation:
Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
