Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.
Explanation:
Basically it means that each virus is specific because of a certain cell makeup or cell membrane. Search up your question on google, there is a site I got this from! :)
Answer;
B. The offsprings will inherit one gene from each parent.
Explanation;
F1 (first filial) generation are the offsprings from the cross between the parents. In this case from Yellow seeds (YY) and green seeds (yy); the yellow seeds are dominant over the green seeds.
After crossing; each F1 generation will contain a genotype, Yy,-heterozygous, which means the phenotype will be yellow seeds since it is dominant over the green seeds. Each offsprings is formed by obtaining one allele from each parent; that is Y allele from yellow seed and y from the green seed.
A is your answer.
Water containing no salt is known as isotonic solution
I believe the answer to this would be A. True
In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.
