The Krebs cycle takes place within the:A. mitochondria
B. lysosome
C. vacuole
D. cytoplasm

Answers

Answer: A. mitochondria

Explanation:

The Krebs cycle is the set of reactions that drives to the complete oxidation of glucose. This occurs in the matrix of eukaryote mitochondria and the prokaryotyc cytoplasm. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. Reactions are catalyzed by enzymes where decarboxylases stand out (decarboxylation catalysts) and dehydrogenases (oxidation-reduction catalysts) leading to the formation of NADH).
The Krebs cycle occurs in the mitochondrial matrix (mitochondria) and generates a pool of chemical energy (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis.

In which situation would a savings account be the best investment to earn interest?A.saving for retirement in twenty years
B.saving to buy a new car in three years
C.saving to buy a new house in seven years
D.saving in July to buy holiday gifts in a few months

Answers

The correct answer is C. Saving to buy a new house in seven years.

You can save to buy a house in seven years which will be profitable because you can rent the house and start returning your money which you spend on buying the land.

Saving is termed as the income which is not spend. Someone can save money by either pension account, investment fund and also deposit account.

Saving reduces expenditure, for example, recurring costs. It is closely related to physical investment.

A savings account would be the best investment to earn interest is saving for retirement in twenty years. The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant characteristic. The flower color trait in radishes is an example of which of the following?
A) a multiple allelic system
B) sex linkage
C) codominance
D) incomplete dominance
E) epistasis

Answers

The answer is D) incomplete dominance.

Incomplete dominance occurs when heterozygous phenotype is intermediate to the dominant homozygous and recessive homozygous phenotypes. In radish flowers, purple is intermediate to white and red flowers. So, purple color is characteristic for heterozygous phenotypes. When dominant red flowers are crossed with recessive white flowers, all offspring will be heterozygotic and with intermediate - purple color.

Final answer:

The flower color trait in radishes, as described in your question, is a classic example of incomplete dominance, as the offspring's phenotype (purple flowers) is a blend of the parental traits (red and white flowers).

Explanation:

The flower color trait in radishes, as described in your question, is an example of incomplete dominance. In incomplete dominance, neither allelic version of the trait is completely dominant, resulting in an offspring phenotype that is a blend of the parental traits.

In your presented case, neither the red flower trait nor the white flower trait is entirely dominant, which is why a cross between a red-flowered and a white-flowered radish produces all-purple offspring. This is a classic example of incomplete dominance in biology.
