Answer:

Option (d).

Explanation:

Equilibrium may be defined as the state of the equality on both the sides of the reaction. Different types of equilibrium are physical equilibrium, chemical equilibrium and dynamic equilibrium.

Chemical equilibrium may be defined as the equilibrium in which the reactants and products concentration remains constant with time. The rate of the backward reaction is equal to the rate of forward reaction.

Thus, the correct answer is option (d).

7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white

kondor19780726 [428]

Answer:

See the answer below

Explanation:

Genotype is the genetic composition of organisms and a gene is made up of two alleles.

a) Since the allele for black is B, the genotype for black chickens would be BB.

b) Since the allele for white is W, the genotype for white chickens would be WW.

c) Since erminette color is heterozygous, the genotype would be BW.

d) Two erminette were crossed:

BW x BW

BB BW BW WW

i. Probability of having black chick (BB) = 1/4

ii. Probability of having a white chick (WW) = 1/4

iii. Probability of having erminette chicken (BW) = 1/2

Which structure is labeled X in the diagram below?

Vladimir [108]

Answer:

Option D

Explanation:

Diagram is attached.

Capsid protein is a form of structural protein which usually forms part of a complex which later produces protective shell around the nucleic acid in a virus. It is also referred to as coat protein or head protein.

Capsid acts as a distinguishing feature for identifying an integrated viral genome, plasmids and other genetic material of viruses. In fact, viruses are termed as organisms that encode capsid proteins.

Hence, option D is correct
