Answer:
Bottleneck effect
Explanation:
The Bottleneck effect is when species go through an event that reduces its population. The ones that survive have reduced genetic diversity compared to the original population since fewer individuals means there are fewer genotypes.
Answer:
b) electron transport chain
Explanation:
During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.
Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
Answer:
B. Protein is composed of DNA which is produced in the cell
Explanation:
Answer: Oxaloacetate
Explanation: The krebs cycle starts with the pyruvic acid that is obtained after glycolysis. The Kreb's cycle begins when the Acetyl coA combines with a four molecule oxaloacetate.
The main product formed is citric acid thats why the cycle is also called as citric acid cycle. After the citric acid is formed it goes through a series of reactions to form NADH, FADH2 and ATP.
The carbon dioxide is also released during this process. The oxaloacetate formed is used to start the cycle so its is regenerated again and again.
