Answer:
The enzyme is the pyruvate kinase
Explanation:
The designated enzyme can only grow in pyruvate or in ethanol. They are said to be in anaerobic conditions. If the end product of glycolysis is pyruvate and the enzyme that transforms phosphoenol pyruvate into pyruvate is called pyruvate kinase. In a reaction under anaerobic conditions, the pyruvate is transformed into ethanol. So if the pyruvate kinase enzyme is mutated, pyruvate cannot be transformed into ethanol and Saccharomyces cerevisiae could not survive in that medium.
Answer:
A: Suited for their environment
Explanation:
You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.
Hope this helped!
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Answer:
Limbic System
Explanation:
The limbic system of the brain is responsible for behavioral and emotional responses.
Answer:
If a person has a diet high in saturated fats, LDL cholesterol molecules can carry cholesterol from the liver to cells and to the arterial walls whereas HDL cholesterol transports cholesterol from the cells to the liver where it is converted to bile salts which can modulate cardiovascular function.
Explanation:
Cholesterol is a lipid generated in the liver that is used to make hormones and vitamin D, but can also be ingested when eating fats.
Cholesterol can be divided into two types: LDL (low-density lipoprotein) and HDL (high-density lipoprotein).
LDL is commonly known as the "bad cholesterol" and is responsible for the deposit of cholesterol in the walls of arteries, which generates atherosclerosis and can potentially lead to strokes or heart attacks because it occludes the vessels and makes it impossible for the blood to advance.
HDL is also called "good cholesterol" because it takes the cholesterol from the cells to the liver where it'll serve a good cause, instead of blocking the arteries.
To reduce the amount of LDL, it's best to limit the consumption of fatty meats, dairy products and other saturated fats. Foods with a good amount of HDL are those with unsaturated fats, like fish, nuts and seeds.
