Answer:

isometric contraction

Explanation:

Isometric contraction is a class of contraction where the muscle maintains a constant length as tension is produced, thereby the length of the muscles does not change during this process. Isometric contractions are performed without joint motion. They are appropriate for the rehabilitation of musculotendinous traumas due the muscle maintains a static position and contraction intensity can be controlled. This type of contraction is common for the muscles in the hands and arms.

Anna11 [10]

Answer:

It is a seeded vascular plant.

It does not depend on insect pollination.

Explanation:

The complete question is: <em>A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant. </em>

<em />

<em>The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.</em>

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.

What is are amino acids????
Anon25 [30]

Amino acids are the monomers that make up proteins. Amino acids are made of a carboxyl group (Carbon, Oxygen, Hydrogen), an amino group (Nitrogen and two Hydrogen), and finally an R group which differs in each amino acid. That R group is what makes each amino acid different! They can also act as enzymes. Essentially enzymes act as biological catalysts and control the functions of the cell and build cells.

Dude why is bio so hard please help lol
Evgesh-ka [11]

Answer:

1.Sugar bonds

2.Transport proteins

3. Digestion

4. Oxidation

explanation

Chemical energy is stored in the bonds of sugar.

The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.

Digestion converts chemical energy into kinetic energy used by cells.

When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
