LekaFEV [45]3 years ago
7 0

Answer:

Enzyme catalysis is detected by measuring either the appearance of product or disappearance of reactants. To measure something, you must be able to see it. Enzyme assays are tests developed to measure enzyme activity by measuring the change in concentration of a detectable substance.

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport
Julli [10]

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The answers are as;

a) 1. NADH and 7. FADH2

b) 6. O2

c) 3. NAD+, 1. H2O, 4. ATP and 8. FAD

Oxygen is the ultimate electron acceptor, and it combines with hydrogen ions to produce H2O. This process occurs at the conclusion of the electron transport process.

ATP molecules, which are carriers of energy, would be the final outcome of the oxidative phosphorylation process.

(a) NADH and FADH2 donate electrons to the electron transport chain.

(b) O2 is the final electron acceptor.

(c)  NAD+,  H2O,  ATP, and  FAD are the final products of the electron transport chain and oxidative phosphorylation.

You can also learn about oxidative phosphorylation from the following question:

Tim and Stephanie are devastated when they find out their newborn son has hemophilia - an x-
IrinaK [193]

First of all, hemophilia is an x-linked recessive and recessive disease. So it's a genetic disease.

  • Therefore, there is no possibility of snatching it from his son. It can come from mom or dad. If the mother and father do not have this disease, as in the question, the mother carries this disease recessively. If it was a girl, she would be less likely to get the disease, as she would have to inherit the genotype of this disease from both the mother and the father. however, since her children are boys, she received the disease gene from the mother's recessive gene region. Therefore, the boy has hemophilia in the XhY genotype.

I need URGENT help with 16 through 18 pls!!!
8_murik_8 [283]

Answer:

16. Directional Selection

17. Disruptive Selection

18. Stabilizing Selection

19. Natural Selection

20. Adaptation

Explanation:

In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.

Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.

Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
