Answer:
4. The given statement is false.
Correct statement: The pyruvic acid produced in glycolysis enters the mitochondria if oxygen is present in a cell.
Explanation: Pyruvate is transported into the mitochondria with the help of pyruvate translocase (transport protein located in the membrane of the mitochondria) where it is decarboxylated in order to produce acetyl-CoA.
5. The given statement is false.
Correct statement: In the matrix, pyruvic acid is converted to acetyl-CoA before the Krebs cycle begins.
Explanation: In mitochondrial matrix, pyruvate is decarboxylated to produce acetyl-CoA which enters the Krebs cycle.
Pyruvate is converted into lactic acid in the cytoplasm when cell undergoes lactic acid fermentation due to lack of oxygen such as in muscle cell.
6. The given statement is true.
Acetyl-CoA condenses with oxaloacetate (4-carbon compound) to produce citrate (6-carbon compound).
7. The given statement is True.
CO₂ is released as the byproduct of cellular respiration which is removed out of the body.
Other products such as NADH, and FADH₂ are used in electron transport chain which aids in the production of ATP.
<span>The answer is a. stabilizing selection.
This is the correct answer because genetic phenotype's among alligators and crocodiles were conserved during the evolution of the species. The reptiles have very little phenotypic variation or difference in physical traits, which would is the result of a stabilizing genetic selection process.</span>
Answer:
The answer is Behavioural isolation.
Hope that helps. x
She didn’t cycle the reaction! She has to cycle as follows:
1. 95C-to denature the double stranded DNA
2. 50-55C depends on her primers- to anneal the primers to the single stranded DNA
3. 37-42C depending on the enzyme used - DNA polymerase extends from the primers to make the new DNA.
Also, are the dNTPs special? Either radioactive or with a fluorescence to measure/detect them?
