Humans are diploid organisms that have 23
pairs of chromosomes (or 46 chromosomes) in
all somatic or body cells. These cells divide by
mitosis that forms daughter cells with same
number of chromosome pairs as present in
parent cell.
In humans, gametes (eggs and sperms) are
formed from the germ cells by the process of
meiosis that leads to reduction of chromosomes
in daughter cells (with half the number of
chromosomes as present in parent cell).
Thus, the correct options are:
-bone cell has 46 chromosomes, as bone is a
somatic cell.
-Skin cell has 23 chromosome pairs (46
chromosomes), as skin cell is somatic cell.
-gamete has half the chromosomes (23
chromosomes) of a red blood cell (46
chromosomes) as red blood cell is somatic cell.
Because they are probably not adapted to live with those animals
Answer:
Only C) is correct.
Explanation:
Water is not synthesizes by the plant.
The atom count is the same. They've only bonded in molecules.
Less carbon dioxide is released due to carbon being bonded in glucose.
<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.
