Answer:

The correct answer is E. All of the above

Explanation:

Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.

During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.

Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.

Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.

Afina-wow [57]

Answer:

False

Explanation:

Active transport is one of the two major kinds of transport (the other being passive transport). Active transport involves moving substances against their concentration gradient i.e. from where they are low in concentration to where they are high in concentration. Hence, energy input in form of ATP is required by the cell to make this occur.

As stated in this question, the Na+/K+ (sodium-pottasium) ATPase pump is an example of active transport, which requires energy to move sodium ions. However, in active transport, substances are moved from a lower concentration to a higher concentration and not otherwise as depicted in this question, hence, it is FALSE.
