<em>The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.</em>

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.

Should the FDA should give Aquabounty permission to grow and sell transgenic salmon? Why or why not?
True [87]

Answer:

Yes it should be approved

Explanation:

The FDA should give Aquabounty permission to grow and sell transgenic salmon because studies have shown that transgenic salmons which are genetically modified are harmless. This finding has allayed the fears of the people. Permission to grow and sell this type of salmons will make it easier for transportation to other parts of the country because it doesn’t necessarily have to come from the sea. It also ensures there is increased availability of the products all over the country.
