The best answer is A
Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.
Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.
To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.

Answer:
DNA Replication
Explanation:
Ensures that resulting cells contain entire genome
Answer:
It would harm the few plants that benefit from mutualistic relationships with mycorrhizal fungi
Explanation:
Mycorrhizal relationship is a symbiotic relationship between fungi and the roots of higher plants. While the plant provides the fungi with food, the fungi supply the plant with nutrients and water extracted from the soil.
<em>Hence, if a wide-spectrum fungicide is used in a forest and it kills all the fungi in the forest, it will affect all the plants that share beneficial relationship with fungi in the forest.</em>
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.
