Answer:
Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.
Explanation:
To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
Answer:
The animals adapt to survive.
Explanation:
If a giraffe can't reach the food that another one can, that giraffe will die and the longer necked one wll survive. Adaptations over time cause evolution. The fittest will survive. (Darwinism)

Epithelial tissue lines the cavities and surfaces of organs and blood arteries throughout the animal body, whereas connective tissue supports, links, and divides many types of tissues and organs in the body. This is the main distinction between epithelial and connective tissue.
Cell arrangement: The physical properties of the Epithelial tissue affect how the connective tissue is organized. There are different arrangements of epithelial cells, such as squamous, cuboidal, and columnar, that organize as simple, stratified, pseudostratified, and transitional. Since epithelial cells form from ectoderm, mesoderm, and endoderm, this explains why epithelia line body cavities. Dense irregular connecting tissue is made up of messily organized tightly packed collagen bundles.
