Answer:
Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
The answer is The bone will become soft and Flexible
Inorganic component of bone would be consist of calcium and other deposition that makes the bone hard. The inorganic components are easily dissolved by acid which are used by osteoclast cell to remodel the bone. After the inorganic component removed, the bone will lose its hardness which make them more flexible.
Answer:
The correct answer would be
- It cures all cases of cystic fibrosis.
-
It involves the modification of DNA.
- It attempts to replace a mutated gene with normal DNA.
- It does not always cure patients who use it.
Gene therapy is an experimental technique used to treat the genetic disorder by transplanting the normal gene into the cell in order to replace the missing or defective gene in a cell.
It helps in treating genetic disorders such as cystic fibrosis, hemophilia et cetera.
It can be of two types of somatic gene therapy and germline gene therapy.
Answer:The seminal vesicles produce mucus to neutralize the acidic environment of the vagina.
Explanation:
The seminal vesicles is found in male reproductive system which produces mucus that is alkaline in order to protect the sperm from the acidic environment of the female vagina . This also contain sugar to nourish the sperm.
The vargina is the outer opening of female reproductive system that receives the sperm. It is acidic in nature because it discharge fluids that contain liquid, cells and bacteria that lubricate and protect it.
