Answer:
- <u>Cell has a limited supply of NAD+</u>
Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.
Answer:
Zebra mussels are spread from one body of water to another by natural flow, carried on the feathers or feet of birds, or by humans in bait buckets or on boats.
Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.
Explanation:
Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)
Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>
After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
