It is obvious that the sandstone is older than the granite. This is because the sandstone had to already exist when the granite formed from molten rock, as some of the sandstone was captured within the layer of hardening granite. The geological principle of inclusions supports this conclusion.<span> Inclusions, in this case the sandstone, are always older than the rock they are found in. </span>
Answer:
the answer is D: the the preservation of species
Explanation:
Genotype of the Q gene is homozygous dominant
The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.
Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.
The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.
Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.
Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
Answer:
Stored as fat
Explanation:
The body requires a variety of macro nutrients for building blocks to fortify the body and keep it functioning. One of the important building blocks are amino acids that are derived from proteins. These are broken down in the stomach by protein digestion enzymes by amylase, proteases and hydrochloric acid.
In the even that the body has taken in too many units of protein this will be stored in the liver as glycogen. This is a form of "animal carbohydrate" or "animal sugar."
The glycogen stores will remain there for a reservoir for energy whenever the body requires it. In the event of overeating the body will store the glycogen in a more concentrated form, fat via the fatty acid synthesis pathway.
