A.V. Hill was the first kinesiologist to contribute to the field of exercise physiology with his Nobel Prize-winning work on metabolism.
Understanding the impact of activity or exercise includes concentrating on unambiguous changes in muscles, cardiovascular, and neurohumoral frameworks that lead to changes in practical limit and strength because of aerobic exercise or strength. To work, our muscles need energy, which is delivered by chemical and hormonal cycles. During the 1910s Archibald Hill framed these cycles by investigating muscles from frogs. Contrary to the predominant view that mechanical development and chemical cycles were equal arrangements, Hill had the option to appear through estimations of intensity created by the mechanical cycles that these were postponed corresponding to the movement. The chemical succession comprises a work stage, which isn't reliant upon oxygen supply, and a recuperation stage when oxygen is required.

Sexual reproduction:
Advantages: A species can evolve or adapt to changing environments, genetic diversity
Disadvantages: Time and energy needed to find a mate, requires both male and female gametes, one individual cannot reproduce
Asexual reproduction:
Advantages: Only one individual is needed to reproduce, doesn’t require time or energy to find a mate, can reproduce rapidly in good conditions
Disadvantages: No genetic variation, all of the offspring have the same weaknesses, can’t adapt or evolve
<h3><u>Answer;</u></h3>
Parent cell (mother cell)
<h3><u>Explanation;</u></h3>
- <em><u>Cell division refers to the process by which a parent cell divides into two or more daughter cells. There are two major types of cell division, mitosis and meiosis.</u></em>
- <em><u>The original cell that divides is known as the parent or mother cell, while the resulting cells are known as the daughter cells.</u></em>
- During the process of meiosis, which occurs in somatic cells the parent cell divides into two identical cells which are similar to the parent in terms of the number of chromosomes, while during meiosis which takes place in the gonads, a parent cell divides into four daughter cells that contain half the number of chromosomes as the parent cell.
Answer:
A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.
