Biology

fredd [130]3 years ago
8 0

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.

Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

Amanda [17]
The correct answer is the suprachiasmatic nucleus of the hypothalamus. The suprachiasmatic nucleus, as the name suggests, is the part of the hypothalamus located in right above above the optic chiasm. The main function of the suprachiasmatic nucleus is mainly responsible for the circadian rhythm of the body therefore the physiological activity on daily cycles.
