Answer:
The correct answer is: Eccentric phase.
When talking about movement, we are talking about the activation of muscle fibers in order for this process to happen. In order for this to happen, motor neurons must activate the phases of muscle excitation, contraction and relaxation, so that the sarcomeres, and thus the fibers, can generate movement.
In essence, there are three stages, or phases, to complete muscle movement: the concentric phase, which is when the muscle fibers are excited and begin the process of contraction. This means the muscle fibers will contract and generate movement, generating a shortening. Then we have the isometric stage, a moment in which there is no longer any more shortening of the muscle fibers, so basically, the movement is held and there is no further contraction, but neither is there relaxation of the muscle fibers. Finally, we have the eccentric phase. This phase is characterized precisely because it is the moment when the muscles begin to return to their resting position.
The answer is a. evade predators.
Animals that live in taiga had to adapt to seasonal changes, by changing their fur or feather color. For example, snow-show hare and ermine live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way<span> it is more difficult for their predators to spot them.</span>
The flu vaccine is essential in our society and should be encouraged and financed whenever necessary. That's because, as we know, the flu is a disease of rapid proliferation and that imposes risks to the lives of some people. The vaccine has the ability to reduce the risk of a person being infected with the flu virus by 50%, this percentage is essential for people who are more sensitive to this virus such as the elderly, pregnant women and people with respiratory problems.
In addition, it is important that the manufacture and distribution of this vaccine is always financed, because the flu virus is a very changeable circle that is constantly changing and needs to be combated annually.
