A) You want to determine biochemical and physiological characteristics.

Explanation: selective media such as MacConkey agar is used to grow, determine and study a particular organism. It allows the growth of the target organism and inhibits the growth of others thereby giving one organism to study at a time instead of growing different organisms and isolating the organism of study. It is specific.

Differential media is used to differentiate, compare and contrast two or more organisms.

D) You only want to determine the cell wall type, not any biochemical

Explanation:

Basically selective media is used in the culture medium meant for growing only a specific microorganism, while preventing the growth of any other microbes in the medium.It is used for ensuring the growth and survival of a desired microbe with a desired characteristics, while suppressing the growth of unwanted competitor. it its primary use it to ensure the survival of needed microbes, while neutralizing or killing any unwanted microorganism.

However, in order to distinguished one organism from another in a culture medium , that is to find out if a micro organism is present or not, biochemical properties displayed by the organism when an indicator is added to the medium is usually used . That is to identify a specific microbes and therefore to differentiate from others in the media . It characterise the growth of a particular microorganism based on the biochemical properties observed when an indicator is added. it does not kill the other microbes present.

Based on this, option D is correct, because, the objective was not to identify the microorganism based on biochemical properties;or to distinguished one microbes from another;but rather to select the organism through identification of the cell structure.

Ifound this on google “aristotle (384–322 bc) in western scientific taxonomy the greek philosopher aristotle was the first to classify all living things, and some of his groups are still used today, like the vertebrates and invertebrates, which he called animals with blood and without blood.” i hope this you for what your looking for.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
