Answer:
D.
Explanation:
Fermentation does not make ATP, but it allows glycolysis to continue.
Fermentation removes electrons from NADH molecules and recycles NAD+
molecules for glycolysis.
Answer:
A. amount of food available
Explanation:
An experiment consists of two types of variables, independent and dependent. Value of independent variable is decided by the person doing the experiment and is independent of experimental conditions. Value of dependent variable is dependent on the independent variable. It can not be altered by the person doing experiment.
Here, it is given that mice receive variable amount of food each day and their lifespan is recorded. Since the amount of food is decided already it is the independent variable. The lifespan is expected to depend on the amount of food hence it is the dependent variable.
Answer:
Epithelial
Explanation:
Epithelial tissues are the tissue that covers the body surfaces and line the body cavities. The cells of this tissue form a continuous sheet and are arranged in single or multiple layers. These cells are closely packed and there is little or no intercellular space. Epithelial tissue covers and lines various surfaces. For example, the body surface is covered with skin which is made up of epithelial tissue. The function of epithelial tissue is to protect the underlying parts, secrete mucus, hormones, and enzymes and to absorb and excrete substances.
Answer:
The correct answer will be option-E.
Explanation:
Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.
These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.
Thus, option-E is the correct answer.
