Answer;
-Special stains
Explanation;
-Cell staining is important in the diagnosis of microorganisms because bacteria can be identified by the color differentiation of stains (dyes).
-Microscopic examination of stained cell samples allows examination of the size, shape, and arrangement of organelles, as well as external appendages such as the whip-like flagella, which are the cell's organs of motion. When sample cells are stained to show their chemical composition it is called differential staining.
-Special stains are used to help visualize and/or identify structures and substances in sections.
Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.
Answer: they are called micro organisms
Explanation:
Most of the galaxies in the Universe are moving away from us and as a result, the light that they emit is shifted to the red end of the spectrum due to an increase in wavelength as the Universe expands. When a galaxy moves towards us, for example in the case of the Andromeda Galaxy (M31), the wavelength of the light emitted is shortened thanks to the Doppler Effect (the same effect that causes the siren of an ambulance to rise and fall in pitch as it drives by), shifting the light to the blue end of the spectrum. The galaxy is then said to be blue-shifted.
