Which statement concerning osmosis and active transport is correct?

1 answer:

3 0

The question is incomplete, however, the statements associated with this question is given in the comments and here as well:

Neither facilitated diffusion nor osmosis requires cell energy.

Diffusion of gases and other small molecules requires no energy on the part of the cell.

Active transport requires cell energy and osmosis doesn't.

Both endocytosis and active transport require cell energy.

Answer:

The correct answer is - Active transport requires cell energy and osmosis doesn't.

Explanation:

Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.

In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.

Which phenotypic ratio is likely to occur in a dihybrid cross of two completely dominant, independently segregating gene pairs w

kirza4 [7]

Answer:

9:3:3:1

Explanation:

If two parents for a dihybrid cross are fully heterozygous for two genes, the phenotype ratio comes 9:3:3:1. Here, the alleles of both genes should exhibit complete dominance-recessiveness. This means that one allele of a gene should be able to mask the expression of its another allele. Similarly, alleles of one gene genes should assort in a random manner during anaphase-I irrespective of the assortment of alleles of another gene.

Under these conditions, each parent produces four types of gametes in equal proportion. And the random fusion of these gametes gives progeny in 9:3:3:1 phenotype ratio.

For example, a dihybrid cross between TtRr and TtRr would produce progeny in the following phenotype ratio=

9 tall and red: 3 tall and white: 3 dwarf and red: 1 dwarf and white

Here the allele T gives "tallness" while the allele "t" gives "dwarfism". The dominant allele "R" gives "red flowers" while the recessive allele "r" gives white flowers.
