Blood flow through an arteriole when it dilates.

nikitadnepr [17]

Answer:

The correct answer will be option C - increases.

Explanation:

The dilation or vaso-dilation is the widening or increase in the diameter of the blood vessels- arteries, arteriole and veins.

The vasodilation is caused by the relaxation of the smooth muscle which results in the increased flow of the blood through these vessels due to a decrease in the vascular resistance.

Thus, option C - increases are the correct answer.

Bryophytes (non-vascular plants) ________. are more similar to ancestral green algae than are vascular plants can be included in

choli [55]

I think in this case Bryophytes are more similar to ancestral green algae than are vascular plants. These plants lack a vascular system for transporting water and minerals, Unlike angiosperms they do not produce flowers, fruits, or seeds. They also lack true leaves, roots, and . stems, They appear as small, green mats of vegetation found i damp habitats. Lack of vascular tissues means that these plants must remain in moist environments.
