Answer:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies.
Explanation:
Storms, which are severe weather conditions, develop when air pressure differences speed up air flow.
What do you mean by atmospheric pressure differences ?It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. Weather is predicted by atmospheric pressure. There will often be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.
Air density variations, which are connected to temperature, are what are causing this shift in pressure. Because heated air's gas molecules move faster and further apart than cooler air's, warmer air is less dense than colder air.
Thus, various weather patterns are seen with change of atmospheric pressure.

What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.
If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Essential amino acids are available to the body through diet.
What are amino acids?Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.
Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.
There are twenty different amino acids present. Amino acids are classified into four main groups:
Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acidsAmino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.
Amino acids are joined together in large number and form polypetides through peptide bond formation.
Based on the nutritional requirements amino acids are classified into two types:
Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.
Aside from solar energy, what else could provide electrons?
Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature.
Small charged particles called electrons, which normally flow via a wire, provide electrical energy. An illustration of electrical energy in nature is lightning.
What are the different sources of electron?The majority of free electrons are created with minimal kinetic energy and just disperse through the atmosphere, participating in the random thermal motion of every atom.
With enough kinetic energy, some free electrons are created that can lead to further ionization and excitation.
The source of electrons is a filament, or cathode. Usually, it is a tungsten wire in the form of a hairpin.
The surrounding cathode cap is given an accelerating voltage (determined quantity of negative high voltage). The filament is then exposed to a tiny emission current to liberate electrons.
Therefore, aside from solar energy, electron are produce.

Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

In one sentence explain why carbon dioxide is considered the most important greenhouse gas, although it traps much less heat than other greenhouse gases such as methane, nitrous oxide and CFCs.
Answer:
Because plants need carbon dioxide more than any other compound/element. Also, heat doesn't make much of a difference in a plants growth or production. It's sunlight that makes a difference.
Carbon dioxide is considered as the most important greenhouse gas due to its abundancy in the atmosphere.
• In the atmosphere, climate change is mainly an issue due to high concentration of carbon dioxide in the atmosphere.
• This overload is because of the burning of fossil fuels and burning of forests.
• Apart from carbon dioxide there are many heat trapping gases like water vapor and methane, however, carbon dioxide is putting us at greater threat due to irreversible modifications it takes place if it continues to gather at such rate in the atmosphere.
• Carbon dioxide has contributed more to climate change than any other greenhouse gases between 1750 and 2011.
• The other gases like methane possess more potent heat trapping tendency per molecule in comparison to carbon dioxide, however, they are far less in comparison to carbon dioxide in the atmosphere.
• The tendency of carbon dioxide to remain in the atmosphere for longer durations in comparison to other heat trapping gases makes it the most potent greenhouse gas.
Thus, the abundancy of carbon dioxide in the atmosphere makes it the most powerful greenhouse gas in comparison to other greenhouse gases.
