QUESTION 1
nata0808 [166]

Answer:

According to the sliding-filament model of contraction, the muscle contraction occur due to the myosin heads propel the actin myofilaments toward the center of the sarcomere. This pulls the Z disks closer together, shortening  sarcomere and the entire muscle

Explanation:

In the muscle fiber there are two proteins that facilitate the process of contraction, myosin and actin. Myosin is thicker and more abundant than actin, and its interaction is responsible for the process of muscle contraction.

Both molecules, myosin and actin, form bonds -called cross bridges- where the myosin heads produce the mobilization of actin towards the center of the sarcomere. Z discs are associated with actin myofibrils, so they come close, and promote the shortening of the sarcomere.

This process requires the action of calcium ions, which depolarize the muscle cell and consume energy in the form of ATP.

It should be noted that the myosin and actin molecules do not change their length, but their action causes the muscle fibers to shorten during contraction.

The carrying capacity for a species in an ecosystem is primarily determined by
coldgirl [10]

The carrying capacity for a species in an ecosystem is primarily determined by the resources in the ecosystem.

<u>Explanation:</u>

The availability of food, raw materials, water and other resources in that ecosystem are those factors that is used for the determination of the carrying capacity. The factors such as nature, the levels of wastage accumulation, removal of very important things from the system also determines the carrying capacity. a system's carrying capacity may involve matters such as available supplies of food, water, raw materials, and/or other similar resources.

The main components that determines the carrying capacity of an ecosystem are food and other resources, provided, the humans must not disturb the ecosystem for their self survival. The resources limitations and their availability determines this factor to a greater extent.
