Answer:
C) Selective and differential medium.
Explanation:
Selective Medium:
A media contains specific ingredients which are required to promote the growth of microorganism and inhibit the other microorganisms to grow is called selective medium.
Differential Medium:
A media contains specific ingredients which differentiate the same group organisms or closely related organisms is called differential medium.
NaCl is used in media to promote the growth of Staphylococcus aureus and inhibit the growth of other gram positive and negative bacteria.
A yellow halo color shows the bacterial fermentation of sugar which will distinguish Staphylococcus aureus with other strains.
So, it will be selective and differential medium which will allow to grow Staphylococcus aureus and differentiate with other bacteria.
The answer is D. Species A will have fewer phenotypes.
Alleles are alternative forms of a gene. In species A, the leaf color is controlled by two alleles, for example, P and Q. They will have three possible genotypes - PP, PQ, and QQ. Three different genotypes give maximum three phenotypes.In species B, leaf color is controlled by three alleles, for example, L, M, and N. They will have six different genotypes - LL, LM, LN, MM, MN, and NN. Six different genotypes give maximum 6 phenotypes.
