What is a similarity between limestone, obsidian, and quartzite?

Biology
1 answer:
ki77a [65]3 years ago
5 0

Answer:

It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks. Sandstone will shatter into many individual grains of sand while quartzite will break across the grains.

Identify three environmental influences on microbial growth. How does each affect microbial distribution?
Alenkinab [10]

Answer:

1.Temperature

2.Moisture

3. PH: acidic or basic concentration

Explanation:

Different microorganism grow at different temperature. For example, many human-disease-causing microbes have an optimum temperature of 37C, and most of the bacteria do not grow at temperature higher than 45C. This means that any temperature lower than 45C will favor the growth of certain bacteria while higher temperature may cause death or reduction in the population of most. Hence, the effect of temperature on these organisms.

Water is required to dissolve the cell substances in microorganism just like higher animals.  while some can survive under an extremely dry condition, most can't and this could result in death or reduction in population.

PH, a measure of the hydrogen concentration in a solution for most microorganism is between 6-8, too much of acid or base could disrupt the activities of these organisms and a maintained range ensure an optimal survival.

There are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitami
KiRa [710]

Answer:

<u> Essential</u> nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.

You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to <u>micronutrients</u> which you consume in small quantities

<u>Dehydration</u> can develop very quickly when exercising in hot/humid weather conditions.

<u>Proteins</u> are also called 'bodybuilders" due to their function within the body. <u>Amino acids</u> are the building blocks of proteins.

Explanation:

Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body.  They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.  

Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.

The most distinctive characteristic of leaf mesophyll cells is that they are filled with
Katyanochek1 [597]
<h2>Mesophyll cells</h2>

Explanation:

The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts

Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis

Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side

The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases

What are two techniques used to restore biodiversity
Zarrin [17]

Two techniques that are used in order to restore the biodiversity are the sawing of native seeds or planting individual plants, and the reintroduction of animal species native to the ecosystem.

The restoration of the biodiversity is practically trying to get an ecosystem in its initial, pre-destruction condition, and help it function without any human assistance after certain amount of time.

All restorations of the biodiversity are hard and take time, and there's no guarantee that the outcome will be as planned and wanted. Initially, there the sawing of native seeds and planting individual plants, which is crucial as the plants are the basis of the ecosystems. After that animal species are introduced, small and large, herbivores, omnivores, and carnivores. The people initially have to assist the functioning of the ecosystem, but the idea is to make it function properly over time on its own.
