Answer:
A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.
Answer: D.
Explanation:
Viruses can be cultivated within appropriate hosts, such as a living cell . For example, bacteria are grown in an acceptable growth medium to research bacteriophages; then bacteriophagi are added. Within the bacteria, the bacteriophages replicate and greatly increase their numbers.
Diploid cell lines (or strains) are subcultured approximately 100 times before death. A lot more useful in the laboratory and they can be kept in liquid nitrogen forever. The human embryonic fibroblasts are one example of this kind.
As diploid cell line, developed from human embryos have more accurate results and can be stored for longer period of time, they are widely used in cultivation and isolation of viruses that require human hosts.
Hence, the correct option is D.
