The method may be easily applied in order to obtain
additional information for clinical prescriptions from. By new method, we could
easily distinguish gram-positive and gram-negative bacteria in liquid culture
media within 10 min. This modest and fast technique may be beneficial for
determining the treatment course of patients with UTIs, particularly for those
without a prior history of UTIs.
Answer:
A.) The sexual phase can produce variations within the species
Explanation:
Sexual reproduction allows for the mixing of genes which creates variation. Since asexual reproduction just involves one cell, the daughter cells will be identical to the parent. Thus, no variation is created.

b. chronological age
c. psychological age

Answer:
This is because the receptor is in the interior of the cell
Explanation:
When a specific signaling molecule is added to a cell whose cell surface has been stripped off by proteins the cell still responds because the receptor is in the interior of the cell.
Receptors are divided into two categories which are;
- Intracellular receptors or internal receptors which are found in the cytoplasm or nucleus of the cell. They respond to hydrophobic ligand molecules which are able to travel across the plasma membrane
- Cell surface receptors which are found in the plasma membrane
Signalling molecules are necessary for the coordination of cellular responses by serving as ligands and binding to cell receptors.
A type of signaling molecule are the small hydrophobic ligands which can directly diffuse through the plasma membrane and interact with internal receptors unlike the water soluble ligands. This is why the cell still responds after you strip off all proteins on the cell surface.
NOTE: Nitric oxide (NO) is a gas that also acts as a ligand, therefore it can pass through the plasma membrane of the cell and interact with receptors.
Answer: Option 1, 2,3, 4, 5 are all correct.
Explanation:
The spleen is an organ that is located in the left quadrants of the abdomen and it's extend from the 9th to the 11th ribs. It is like the clenched of a fist in shape and it is found between the fundus of the stomach and diaphragm, found underneath the diaphragm. It is a soft mass of lymphatic tissue which is part of the lymphatic system.
Spleen help to filter and remove old blood cells. It function in cell mediated and humoral immune responses.
