Answer:

The correct answer is option D.

Explanation:

Osmosis refers to the procedure by which the molecules of water move from the area where they are highly concentrated to the area where they are present in low concentration via a semipermeable membrane. One use of osmosis is that it provides support to plants.

A hypotonic solution refers to a kind of solution, which possess more molecules of solvent, in the given case it is water and fewer molecules of solute. The freshwater is hypotonic to plant cells, therefore, the cells of the plant captivate water osmotically, and its size increases and become turgid. This produces an external opposite pressure, which is equivalent to the wall pressure that maintains the plant's upright position.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two

andrew11 [14]

The correct answer is B. The parents are heterozygous with polka-dot tails, so they both have Pp genotype. The combination of their genotypes (Pp x Pp) could produce 4 genotypes PP, Pp, Pp and pp. Therefore, there is 25% chance for a PP genotype, 25% for a pp genotype and 50% for a Pp genotype. The PP and Pp genotypes produce a polka-dot tail phenotype and the pp genotype produces a solid coloured tail phenotype. In conclusion, there is 75% chance for a polka-dot tail (25% for a PP + 50% for a Pp) and a 25% for a solid coloured tail phenotype (25% for a pp).

Answer:

Likewise, competition for food among deep-water fish that eat the same types of food will .

Explanation:

Natural selection will condemn all deep-sea fish to the same environment that conditions them, those that cannot develop gills will be exposed to extinction, this refers to the theory of the evolution of the fittest by Charles Darwin.
