A. 4 examples of macronutrients<br> B. 2 examples of micronutrients
vovikov84 [41]
Answer:
Macronutrients: water, fat, carbohydrates, protein
Micronutrients: minerals, vitamins

Explanation:
The six types of nutrients humans need are water, fat, carbohydrates, protein, minerals, and vitamins.

Macronutrients are nutrients we need in large amounts (macro- means big).
Micronutrients are nutrients we need in small amount (micro- means small).

Consider what you eat in a day, you (should) be getting all of these.

It's recommended you have about 8 cups of water a day, which is a large amount.
Fat and carbohydrates are used as sources of energy and are consumed in large amounts.
Proteins (meats, nuts) used to build muscle are also eaten in large amount.

Minerals and vitamins have recommended intakes of milligrams (mg) which is a very small amount. They are found in traces in our food. For example, you would not fill your entire palm with calcium and eat it. You only need small amounts of calcium (probably in your milk).

Why is it important to stain youngcultures of bacteria with<br> the grain stain?
uranmaximum [27]

Answer:

Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.

Explanation:

Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.
