During the _______ phase, the muscle is returning to resting length.
tangare [24]

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.

Which is a difference between proteins and carbohydrates and fats?
morpeh [17]

Answer:

HERE JUST TAKE IT

Explanation:

Ok, there's carbon and hydrogen in all of them, that's the only similarity. They are known collectively as macro-nutrients.

Carbohydrates are basically, oxygen, carbon and hydrogen and they're the bodies primary source of energy. This means that they're the first source of energy used which is why if you eat foods high in simple sugars you get a sugar rush. All carbs metabolize down to glucose, some faster than others.

Fats are called lipids. Lipids are very heterogeneous (this means that there's not much similarity between them). Some examples of lipids are steroids, seed oils, pork fat, cholesterol, etc. The main thing in common with them is that they don't mix with water. They are readily stored in fat cells in the form of tryglicerides and are used when carbs are all used up. They also yield the highest per gram amount of energy (it escapes me right now).

In a chemical sense, fats are lipids derived from animals (saturated, solid at room temperature) and oils are derived from plants and seeds (insaturated with some exceptions, and liquid at room temperature. Insaturated are healthier because they contain HDL which cleans your arteries (prevents artherosclerosis).

Proteins are made up of aminoacids, 20 make up the vast amount of human proteins. Enzimes (the most famous being digestive enzimes) are proteins, skin is covered in protein, hair is protein, cilia and flagella are protein, basically EVERYTHING is protein, after water the human body is basically protein. They're only used up as energy when everything else is used up.

When athletes eat/drink protein, it's to give them building materials in order to increase the amount of stuff inside their cells which will enable them to produce more energy.

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What difference
ipn [44]

Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
