Answer:

Option (a).

Explanation:

Counter current flow may be defined as the flow of water in the opposite direction with the flow of blood in the body. This countercurrent flow is generally occurs in fishes.

The one main benefit of the countercurrent flow is the absorption of maximum oxygen as the water flows inside the body. Approximately, three time more oxygen is extracted during the counter current flow. The concentration gradient is maintained up to the whole length of gills.

Thus, the correct answer is option (a).

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

By decreasing distance and increasing charge on both objects.

Explanation:

Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
