gavmur [86]

Answer:

Option B

Explanation:

When ever a scientific research or experiment is conducted , it is made sure that the results obtained are consistent through multiple trials. Here , only two trials are done i.e one on coast of California and the other on the Pacific Ocean.

Since the number of samples taken for this study are not as per the standard sample guidelines and hence the result obtained can not be considered as a acceptable.

Thus, option B is correct

12 If pressure is applied to a rock until its volume is

mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

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.
