Answer:
Corn crop is resistant to herbicides because they are genetically modified through genetic engineering. There are some bacteria which are resistant to herbicides i. e. no effect of chemicals on that bacteria. So the biotechnologist take a gene from this resistant bacteria and induced it in the corn plant which becomes the part of their genetic makeup. So when we apply herbicide, the gene produces some enzymes which cancel the adverse affect of herbicide and only weeds are affected.
The purpose of meiosis<span> is to reduce the normal diploid cells to haploid cells, called gametes.

Answer:
b) plasmid
Explanation:
A plasmid is an extrachromosomal DNA molecule that found in a cell that replicates independently without the need for chromosomes. A plasmid is small and is also not attached to the chromosomal DNA. Generally, plasmids are a circular piece of double stranded DNA materials that are present in bacteria.
Plasmids are used in a molecular biology laboratory for gene manipulation. they are able to transfer genes to a DNA through DNA recombinant technology and also aid DNA replication in bacteria. Plasmids are also used to study antibiotic resistance.
<span>The cytoplasm of the cells consists of two main elements: cytosol and the organelles. The cytosol is the part of the cytoplasm that surrounds organelles. It is a mixture of cell substances dissolved in water. In prokaryotes, it has an important role in metabolism since most of the reactions take place in the cytosol. Unlike prokaryotes, eukaryotes have organelles, so not all of the reactions take place in the cytosol. Some of them occur in the organelles.</span>
