Answer:

It is a seeded vascular plant.

It does not depend on insect pollination.

Explanation:

The complete question is: <em>A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant. </em>

<em />

<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.

This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.

irina1246 [14]

Answer:

Based on this, you know that Sampson is using the whistle as a <u><em>secondary </em></u> reinforcer to train the dolphins.

Explanation:

Secondary Reinforcement can be described as a condition in which  a stimulus initiates a behavior after being previously associated with a primary reinforcer. A secondary reinforcement is a stimulus that satisfies basic survival instinct such as food, drinks, and clothing.

The same phenomenon was being used by Samson to train his dolphins to perform tasks. The dolphins enjoyed the sound of the whistle because previously that sound was paired to them getting their food.
