Answer:
Vitamins A and D are added to margarine during production so it will have a similar vitamin level to butter. Nutrients may also be added to foods to fortify or enrich them even if the vitamins and minerals added are not normally contained in that food.Margarine makes an important nutritional contribution to the diet by being a source of one or more essential fat-soluble vitamins such as vitamins A and/or D and by being low in saturated fat.
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
There is three types of neurons occur. Sensory neurons typically have a long denfrite and short axon, and carry messages from sensory repeptprs to the central nervous system. Motor neurons have a long axon and short dendrites and teansmit messages from the central nervous system to the muscles.
Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.
Answer: C. It can help some species and hurt others.
The plasma membrane or the cell
membrane is the one that protects the cytoplasm of a cell. It is mostly
composed of lipids and proteins. It has a phospholipid bilayer that controls
the entering and exiting of molecules in the cell and at the same time,
provides protection for the cell or plasma membrane. It has polar head and a
nonpolar tail. Proteins embedded within the phospholipid bilayer have the same
function of the plasma membrane that includes selective transport. The
phospholipid bilayer consists mainly of the lipid molecules.
