Which best explains how muscle cells and skin cells are adapted for our environment? Question 2 options: 1 Muscle cells have mor

Keith_Richards [23]

The correct answer is option 4, that is, muscle cells require more energy, so they have more mitochondria in comparison to the skin cells.

Mitochondria are the powerhouse of the cells. The synthesis of ATP takes place in them, that is, the energy currencies of the cell. The cells of the muscles need to work hard and thus require ample energy, for this, they need more concentration of mitochondria to generate a high energy yielding ATPs.

Leto [7]

In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.

There are three stages in cell signalling :

1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.

2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.

3. Reaction: In the third and last step, the signal causes a certain cellular response.

Molecules cannot react chemically unless they are......

nadezda [96]

Answer:

c) active

Explanation:

When in an atom the outermost shell is not full (eg. 2,8,3 ; here in the last shell it is not filled completely and needs 5 more electrons to complete it ) then the atom becomes active and molecules doesn't react unless and until an atom is active .

Hope it helps you

And pls mark it as the brainiest answer.
