Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures,

lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.

some don't require O2 for survival i.e Spirochete.

IN SHORT, most of the microbes have preferences for various environmental conditions.

Explanation:

Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.

One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.

Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.

Do we classify viruses as living? give support for both yes and no arguments.

ozzi

Viruses are classified as non-living. Although they have DNA or RNA as genetic information, a protein coat, and some, a lipidic envelope, they do not have the machinery to multiply on their own and therefore are non-living. A virus is simply an infectious agent that, through different ways, many times only by releasing its genetic information inside the cell, replicates using other living-cells machinery. Viruses are able to infect any type of cell.
