Answer:
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion
Explanation:
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
Answer:
Craig is right and doesn't have to pay child support.
Explanation:
<em>The complete question is</em>
<em>Susan, a mother with Type B blood, has a child with Type O blood. She claims that Craig, who has Type A blood, is the father. He claims that he cannot possibly be the father. Further blood tests ordered by the judge reveal that Craig is AA. The judge rules that:</em>
<em>a. Susan is right and Craig must pay child support</em>
<em>b. Craig is right and doesn't have to pay child support</em>
<em>c. Susan cannot be the real mother of the child; there must have been an error made at the hospital</em>
<em>d. it is impossible to reach a decision based on the limited data available</em>
- The blood type of a child is determined by the blood type of the parents, and the rules are as given in the attached diagram.
- Based on these rules, it can be observed that a person with type O blood group must have the genotype OO and from this, it can be concluded that both the parents must carry an O allele.
- Since the blood typing has revealed that Craig is AA, he can't be the father of the child and hence, he doesn't have to pay child support.
