What is one way the immune system reacts when a virus enters the body?
Gennadij [26K]

Answer:

As the body tries to fight the infection, the immune system causes inflammation to make it hard for the virus to copy itself. The process of fighting the infection causes most of the symptoms people have. As the virus makes its way down to the lungs it can cause the lungs to become inflamed. This can lead to pneumonia.

Stomata - specialized cells that contract and expand to open or close pores for _______________. Stomata can adjust to temperatu
adoni [48]

Answer:

Stomata - specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying closed when temperatures are hot and dry to prevent gas and water loss.

Explanation:

Stomata (singular stoma) are pores found in the epidermis of plant leaves. Stomata open and close in response to the change in structure of two guard cells either side of the pore opening. When the guard cells are turgid, the stomata open, when they are flaccid, they are closed.

This functions to permit gas exchange while preventing the loss of water, especially during hot, dry weather. The stomata can only open when the guard cells are turgid, pulling the stomata apart.

What does it mean when you have blue dots on the bottom of your feet?
Firlakuza [10]

It means at least one of two things, and possibly both:

-- You have been walking around barefoot on magic markers.

-- You need to see a podiatrist (foot doctor), an expert, who will examine
the area, and then tell you ... based on his expert examination ... either
that it's nothing, or else that it's something that should be treated because
it doesn't belong there.

DO NOT shop on the internet for health or medical advice.
It's possibly the stupidest thing a person can do.
