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.

vladimir1956 [14]

Answer:

pollution levels in the atmosphere

Explanation:

One negative impact of increased production of goods is the increased levels of pollution in the atmosphere.

Pollution is the introduction of harmful substances into the environment beyond levels that are safe for life. The materials are the pollutants.

Production of goods or manufacturing generates a lot of waste with it. Air pollution is easily attributable to manufacturing.

Green house gases from combustion of fossil fuels to drive industrial processes generally leads to climate change.

Smokes and dusts can be produced by industrial processes and when scattered about causes pollution

In a certain triangle ABC , A equals 30°, B equals 50°, and the side AB equals 3 in. Use a protractor and a straightedge to cons

natali 33 [55]

If you were to compute this, Angle C should be equal to 100°.

In a triangle, all angles sum up to 180°.

In triangle ABC, where the m∠A =30° and m∠50°:

m∠A + m∠B + m∠C = 180°
30° + 50 + m∠C = 180°
80° + m∠C = 180°
m∠C = 180° - 80°
m∠C = 100°

The triangle should look like the picture attached.
