Define the rock Cycle. Include the process a rock would go through,starting from volcanic eroption.

Anettt [7]

The rock cycle is a cycle that rocks go through which involves melting, cooling, pressure, erosion, and other stages. Starting with a volcanic eruption, the lava turns into igneous rock, that can be melted into magma again, or can be crushed and pressed into other rocks beneath the crust to form metamorphic rock, or can be broken down by erosion and other factors. For the sake of it, let's say the rock got broken down, it turns into sediment that collects in areas and get layered and pressed, and layered, and pressed some more into a sedimentary rock. That rock can be broken down again, or melted, or pressed with heat and pressure. But let's say it went under the crust with other rocks, mixed with heat, pressure, and other types of rock to become metamorphic rock. Now let's say that metamorphic rock found it's way to a volcano, got melted, and erupted, and cooled to get back to a igneous rock. And the cycle never ends.

<em>Some archaea are known to posses the capacity to carry out a form of photosynthesis using rhodopsin-like ion pumps to move ions against the gradient and produce ATP via chemiosmosis. However, no known archea has the ability to carry out classical photosynthesis like that of green plants.</em>

Why can you catch a cold or flu more than once

Rufina [12.5K]

The flu and the cold are diseases that usually present in mild symptoms, but to be able to say why we can catch them more than once, we need to know that.....

Influenza, is a viral infection of the respiratory system. It is caused by the Influenza virus, which can be type A or B. It is mainly characterized by a picture of symptoms that leaves the person feeling very down and tired, causing a lot of discomfort.

Cold is and how it differs from the flu. To begin with, it is worth noting that it is also a viral respiratory infection. The difference between a cold and the flu is that it can be caused by other types of viruses, such as the more frequent Rhinovirus and Parainfluenza.

The good news is: no, you can't. The bad news is, there are a lot of viruses and germs flying around this time of year, and instead of catching the same one, you have a high chance of catching another.

The body's immune system recognizes and fights off germs, such as viruses that have invaded your blood, the viruses that cause the flu can change each year, so even if you've had the flu recently, it's recommended that you get a vaccine that matches the new viruses that may be circulating each year. Because the flu is caused by several viruses, the immunity you naturally develop after infection will only protect you against that type, so you can catch it from another one as well.

With this information, we can conclude that, we can have flu and cold more than once, because we will be in contact with many viruses that cause the flu and the cold.

shusha [124]

Hello!! I would say that the best answer would be that he told her mom to go to the doctor since she has shortness of breath. Since there was no medical history of eczema or signs, that is probably not the case. Yes, it might be seasonal allergies, but her mom should take her to the doctor just to be sure. Could be exercise induced asthma. Hope I helped!! Have a great day.
