Answer:
The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.
Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.
In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.
In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
Answer:
20 large size leaves plants
40 medium sized leaves plants
20 small sized leaves.
Explanation:
PP = large leaves
P'P' = small leaves
PP' = medium leaves
PP' was crossed with another PP' plant:
PP' x PP'
progeny = PP, 2PP', and P'P'
PP = 1/4 x 80 = 20 large size leaves plants
PP' = 1/2 x 80 = 40 medium sized leaves plants
P'P' = 1/4 x 80 = 20 small sized leaves.
<em>Hence the phenotypes would be:</em>
<em>20 large size leaves plants</em>
<em>40 medium sized leaves plants</em>
<em>20 small sized leaves.</em>
When DNA replicates, each strand of the original DNA molecule is used as a template for the synthesis of a second is known as complementary strand. 5' side on top, broken arrow 3' side on bottom, non-continuous arrow called lagging strand. Continuous strand to 5 to 3 in complementary called as leading strand.

what is Okazaki fragments?
The Okazaki fragments also known as lagging strand that are joined together by the enzyme DNA ligase.
These leading and lagging strands only formed in the DNA replication and DNA polymerase is the enzyme which helps in DNA dependent replication. DNA polymerase forms two identical DNA strands from a single DNA molecule.
