Answer:
B.
Explanation:
A recessive gene is a gene that can be masked by a dominant gene.
True as we need need water to produce roughage and without roughage we cannot digest food.
Answer:
a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system
Explanation:
- Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
- In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
- The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
- The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
The floor of an aquatic biome is called the "Benthic Zone".
Answer:
C.) Nucleus
Explanation:
Chromatin is the main carrier of genetic information and is non-randomly distributed within the nucleus.
