(2) synthesize hormones such as insulin and human growth hormone
(3) increase the frequency of fertilization
(4) eliminate sexual reproduction
Genetic engineering is used in the biotechnology industry to synthesize hormones such as insulin and human growth hormone. Thus, the correct option for this question is B.
Genetic engineering may be characterized as a type of methodology through which recombinant DNA technology is used in order to change the genetic makeup of any living organism. It induces manipulations in the sequences of genes.
The fundamental principle of genetic engineering is to manipulate and modify the genetic material of an organism to incorporate desirable traits. Recombinant DNA technology is the main process or method of genetic engineering.
In recent times, the principle of genetic engineering is used widely in the biotechnology industry for synthesizing numerous hormones such as insulin and human growth hormone.
Therefore, genetic engineering is used in the biotechnology industry to synthesize hormones such as insulin and human growth hormone. Thus, the correct option for this question is B.

Answer:
106 years ago he proposed his model of atoms
Explanation:
Taking Rutherford's model as a starting point. In 1913, Bohr postulated the idea that the atom is a small solar system with a small nucleus in the center and a cloud of electrons that revolve around the nucleus.According to him, electrons are located around the nucleus only at certain well-determined distances.
