Two newly prepared solutions, A and B, contain a red dye. Solution A is darker in color than solution B. We will make two experi

mental observations: Experiment 1: A and B are placed, side-by-side, separated by a semipermeable membrane through which only water can pass. Experiment 2: A and B are placed, side-by-side, separated by a plastic sheet with pin holes. What will happen if we carefully measure the color intensity of solution B after an hour or two

Answer:

The intensity of solution B will increase in experiment 1

But it will remains constant in experiment 2

Explanation:

Experiment 1 - When solution A and solution B are separated by a semipermeable membrane, only water can flow from region of higher concentration to the region of lower concentration. Since, solution B is lighter in color than the solution A, the number of colorings solute particle is higher in solution A. This also suggests that the water concentration is higher in solution B. Thus, water will move from solution B to solution A thereby making it darker in color

Experiment 2 –  

Pin holes are created but the movement of solute and solvent is only possible if there is difference in quantity of both the solutions. Holes in plastic sheet has nothing to do with the  concentration of solute or solvent.

A population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large
natka813 [3]

Answer:

(i) Small island

(ii) Large island

(iii) Option-3

Explanation:

In the given question, the three population of the Anoles Lizards migrated to three islands of different size.

(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.

(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.

(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.
