Answer:
A. 4 right handed coil:0, left- handed coil
Explanation:
According to MENDELION CROSS:
We will get NN, Nn,Nn,nn
NN, Nn, Nn are the 3 right handed coiling and nn is left handed coiling.
But in case of shell coiling in snails, maternal inheritance is applied in which offspring is decided only by phenotype.
Maternal traits: Here,female parent has right handed shell coiling. so, all the offsprings will have the same.
Hence, the phenotypic ratio will be:
4 Right handed coil: 0 Left handed coil
Answer:
2 & 4
Explanation:
The theory of spontaneous generation stipulated that life emanated spontaneously from ‘nothing’. This was believed to be true until Francesco Redi & Luis Pasteur later falsified this theory using an experiment. He had two plates of cooked meat. He covered one with a glass bowl and left the other open. The plate with a bowl did not develop maggots while the open one did. This showed that maggot was as a result of hatched eggs that were deposited by flies. Life, therefore, emanates from life.
Answer:
The two types of lipoproteins are low density lipoprotein and high density lipoproteins
Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.
High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.
