It functions as an adjective
The best answer is C.
Plasma membranes are mainy made up of lipids and proteins. The lipids are glycerophospholipid, molecules composed of glycerol, a phosphate group and two fatty acid chains. Glycerol is a three-carbon molecule that functions as a backbone of these membrane lipids.
Within each glycerophospholipid, fatty acids are attached to the first and second carbon, while the phophate group is attached to the third carbon of the glycerol backbone.
Proteins such as glycoprotein are attched to the glycerophospholipids in the cell membrane. They are used for cell recognition and also act as receptors and antigens.
Answer:
C) adaptations are often compromises
Explanation:
Adaptations are normally intended to make an individual better suited to there enviroment.
It occurs as a result of natural selection and the altered genes or alleles are heritable.
Some adaptations are often compromises. For example, people living in malaria prone regions have high cases of sickle cell anemia to to an adaptation against malaria. Sickle cell is a point mutation in the Beta-globin. The red blood cells will be abnormally shaped hence giving the individual some resistance to malaria.
Due to this adaptation, it compromises there body's intake of oxygen.
Carbohydrates contain carbon, hydrogen, and oxygen in the molar ratio 1:2:1. The empirical formula for carbohydrates is CH20. The monomers of carbohydrates of are sugars.
