the cell theory explains & states this
Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
The answer is D, increasing genetic variation
Answer:
Temperate grasslands have <u>few trees.</u>
Explanation:
Althogh options are not given for this question, here is what I can speculate based on provided limited information.
Temperate grasslands have few trees and large shrubs (mostly absent). Here, <u>grasses are the main vegetation</u>. A major reason behind this is the <u>low average annual precipitation</u> which doesn't allow bigger plants to survive.
For the second part I can say that temperate grasslands have primary vegetation (grasses) whereas other biomes have higher plants as well.
Answer:
<h2>
Proteins even make up most of your hair. ... While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol. Ribosomes are found in many places around a eukaryotic cell.</h2>
