An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes. Do not need to compound it in the form of essay? I know where exactly you can go to get the help with it. PrimeWritings site would be the best choice.
Answer:
Since, we know that the large intestines have so many responsibilities .... The purpose of the intestines is basically to absorb water and including salts from a material, Which means it has not yet been digested as food, and also to get rid of any waste products left over, Also this is very important for the intestines to do this process.
I would say Nucleic Acids
The plants that were allowed to self pollinate were the F1 plants.
The plants that are true breeding are P generation plants.
The plants where there were 3times as many tall plants as short plants are in F2 generation.
<h3><u>Explanation:</u></h3>
This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.
He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.
As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.
As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
Answer is B. Antarctic
71 % of the Earth is cover with water. The large water body is divided and have specific names. There are four distinct oceans. These are Pacific, Indian Atlantic and Arctic oceans. Among these Pacific, Atlantic and Indian are the major oceans. The United States along with most countries now recognize the Southern (Antarctic) as the fifth ocean.
