Answer:

(d) Cell wall

Explanation:

The cell wall is a structure located on the outside of the cell membrane in the cells of plants, bacteria, fungi, and algae. It is a resistant, tough and flexible layer, which has the vital function of supporting the osmotic pressure inside the cell, preventing the cell from lysis when water enters. Besides, it has the function of giving rigidity, support and defining the shape of the cell.

forsale [732]

Answer;

Cycilc AMP

Explanation;

-Second messengers are molecules that relay signals received at receptors on the cell surface; such as the arrival of protein hormones, growth factors, etc., to target molecules in the cytosol and/or nucleus.

-Many of the chemical messengers such as hormones, that transmit messages from one cell to another never enter the target cell, these molecules are known as first messengers which work by binding to a specific receptor on the cell surface. The receptor then stimulates or inhibits the production of a so-called second messenger within the cell.

-The second messenger are small molecules such as Cyclic AMP, which activate an effector within a cell.

Draw the structure of DNA nucleotide with adenine as nitrogenous base <br>​
zavuch27 [327]

Answer:

A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
