Answer: The scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
Explanation-
As per the information given in the question, a mice having mutation in ear depicts same pattern of resistance when compared to another mice having normal ears. This indicates that the genes responsible for resistance are not related to genes that result in ear formation.
Therefore, to find out the effect of diet on disease resistance in rats, the scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

Answer:
a.) freshwater plants may be rooted here--- Shore
b.) littoral zone--- it is the region of a lake or pond that is nearest to the shore
c.) limnetic zone--- A region of open water in lakes and ponds.
d.) alternately dry and submerged--- Intertidal Zone
e.) extends to edge of the continental shelf--- Neretic Zone
f.) generally low nutrient levels
g.) light penetrates here--- Photic Zone
h.) no photosynthesis occurs here--- Aphotic Zone
i.) benthic zone--- this is purely known as the bottom of the lakes or oceans
The nucleus is the one that controls protein synthesis while the nucleolus makes the ribosome subunits. So protein synthesis instructions come from the nucleus but the ribosomes are made in the nucleolus.
