Diffusion occurs because of the movement of molecules from
the region of higher concentration to the region of lower concentration. This
movement of molecules occurs due to a thermal motion. Diffusion normally occurs
between two compartments having difference in concentration. In case of fluid
it moves from the region of higher concentration to the region of concentration
until a balance is reached. The process of diffusion is very important for the
humans as well. The oxygen that humans breathe in gets diffused with the blood.
Answer:
No, it is not
Explanation:
Heterozygous is Gg, and if the dominant gene is there, it masks the recessive one.
It means that the trait is heterozygous. Also, "T" is common used as the letter to represent the trait "Tall".
Answer:
Coral polyps, which are animals, and zooxanthellae, the plant cells that live within them, have a mutualistic relationship. Coral polyps produce carbon dioxide and water as byproducts of cellular respiration. The zooxanthellae cells use carbon dioxide and water to carry out photosynthesis.
Explanation:
Answer No 1:
Phospholipids are made up of phosphorus head and two fatty acid molecules. These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.
Answer No 2:
The building blocks of lipids are glycerol and fatty acids.
Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.
Answer No 3:
Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:
- Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
- Lipids store energy and provide insulation to the body of an organism.
