Answer: Lysosome
Explanation:
The lysosome is an organelle found in cells of eukaryotes.
Its functions include:
I) It contains several hydrolytic enzymes such as
- glycosidases that break down complex sugars (polysaccharides),
- proteases that break down proteins,
- and sulfatases that hydrolyze sulphur-containing compounds,
- other enzymes for lipids and Nucleic acids
II) it also digest worn out organelles, and engulfed viruses and bacteria.
III) and helps to remove wastes from the cell.
Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
B-valine,histidine,threonine,phenylalanine
Angiosperms are grouped into monocots and dicots
They give us the energy we need to move and to speak and to live they do that for all the organisms on earth
