Cell differentiation always involves
mestny [16]

Answer: (C) The production of tissue-specific proteins.

Explanation:

 The cell differentiation is the process in which the cell change from one cell place to another place. It basically occur due to the process of gene expression.

The cell differentiation involve the production of the specific tissue protein known as muscle actin. In cell differentiation, the pluripotent stem cell basically go in the specific differentiation level and then reach in the state of fully differentiation.

The fully differentiation produced a specific function that the production of the protein. Therefore, option (C) is correct.

If you walk through a busy crowd and feel a few different people bump and push past you as they walk by, which skin receptors wo
Likurg_2 [28]

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c wee
mars1129 [50]

Answer:

Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.

Explanation:

Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
