Answer:

The correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.

Explanation:

Isotonic environment is an environment the amount of solute concentration is equal on both side of the semipermeable membrane or the cell. in such condition there would be no water movement towards particular direction or will take place and as there is no water movement so there would be no change in shape or size of the cell. The osmotic pressure in an isotonic environment would be same on both side of the membrane.

Thus, the correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.

What are the two theories that are combined in the synthetic theory of evolution?
Alika [10]

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

<h3>Synthetic theory of Evolution </h3>

  • The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.

The theory explains that changes in the genes of organism are what causes the evolution of organism.

The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.

The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
