When cells respond to an extra cellular signal , they convert the incoming information from one form to another. This process is called signal
a. induction
b. interference
c. transduction
d. transformation

The process is called signal transduction

Explanation:

Signal transduction entails the binding of a ligand or extracellular signal to a receptor and this gives rise to a biochemical cascade of reactions, interactions forming networks and this elicit cellular responses. These responses may include, post translational modifications, changes in gene transcription and translation.

The process is called signal transduction.

Explanation:

Signal transduction is the process by which chemical or physical signal is transfered from outside of the cell to the interior of the cell thereby transforming the information from one form to another form to ensure adequate response. Signal transduction depend on receptors protein.

There are three stages of signal transduction and they are;

1. Receptor or protein present at the cell surface detect signals.

2. Transduction, change in receptors enhance changes in the cell.

3. Response, the cell respond to the signal.

hormones in blood stream

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
