<span>blastocyst
The outer layers of the blastocyst turn in to the trophoblast after implantation. The trophoblast forms the placenta.</span>
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:
The carbohydrates will not be digested properly.
Explanation:
The kind of carbohydrates that a person takes from plants is in the form of amylose. From animals, a person will receive carbohydrates in the form of glycogen,
The digestion of carbohydrates begins as soon as the food is taken in the mouth by the amylase enzyme present in the saliva.
If a person does not have the salivary glands, then there will be no production of saliva and amylase enzyme. Hence, the carbohydrates will not be digested.
Northam Warren created the first commercial version of LIQUID NAIL POLISH in 1917.
As the name implies, the LIQUID NAIL POLISH is used on finger nails, to make it look more attractive and beautiful.
This was after he created the fingernail cuticle remover and nail polish in 1911, and nail tints in 1914.
