Answer:
Explanation:
cells ensures they can work efficiently. If they can't, the functioning of tissues and organs will become compromised which can lead to ill health and disease. Nourishing your cells enables them to look after your body.
Answer:
the process whereby nonsister chromatids exchange genetic material
Explanation:
Crossing-over is a unique phenomenon which occurs only in the prophase I stage of meiotic division i.e. meiosis I. It is the process whereby nonsister chromatids of homologous chromosomes (similar but non-identical chromosomes from male and female parents) exchange their genetic material.
This exchange between nonsister chromatids aids in genetic variation among species that reproduce sexually via meiosis. Hence, meiosis, which is peculiar to sexually-reproducing organisms is the only way that promotes genetic variation in species.

The answer is D.) *are found in organisms of different species*
The presence of ribosomes on the rough ER suggests that the proteins are synthesized as well as modified there as opposed to the smooth ER.
Ribosomes are responsible for the synthesis of proteins from the amino acids. They translate each codon on the RNA template and match it with the appropriate amino acid to make a protein. This process is known as translation. Ribosomes can be found free in the cytosol or attached to the surface of the endoplasmic reticulum. When the ribosomes are bound to it, it is known as the rough ER and without it, it is called smooth ER. Smooth ER performs different functions like the synthesis of lipids and phospholipids. Since it does not have ribosomes, it cannot synthesize proteins.
