Answer:
Diploid
Explanation:
Almost all the animals have a diploid-dominant life cycle. In the early stage of embryo development, the germ cells are made in gonads which undergoes mitosis and meiosis to make more germ cells and haploid gametes respectively. So the resulting zygote formed by fertilization having 46 chromosomes, 23 from each human sperm and eggs. That the reason why the resulting zygote have the characteristic number of chromosomes of that particular species.
C. Bacteria are multicellular
viruses have no DNA or RNA so they can't be unicellular or multicellular
Hihi!
The correct answer is leaves! Leaves are apart of the shoot system, <span>conspicuous part of flowering plants constitutes the </span>shoot system<span>, which is composed of erect stems on which </span>are<span> attached </span>leaves<span>, flowers, and buds. </span>Leaves are<span> attached to the stem at regions called nodes.</span>

Answer:
An Oc mutation on the bacterial chromosome can affect the expression of structural genes on a F plasmid.
Explanation:
An Oc mutation is a mutation in which operator of an operon is constitutively active i.e. repressor fails to bind the operator which leads to unregulated gene expression.
An Oc mutation do not affect the expression of structural genes on F plasmid because <u>an operator is a cis regulatory element and therefore it can only affect the genes which are located on the same DNA</u>. F plasmid genes are located on the plasmid not on the main chromosome of the prokaryotes while tryptophan or lac operon system is in the main chromosome that is why an Oc mutation will not impact genes on plasmid.
for one and c are closer alike to each other as the rates of recombination depend on the likeness of that gene
