Vascular plants is the phloem, (vessal) that transports food and the xylem transports water. Nomvascular plants are small with no vascular system. Which means non vascular plants do not have a phloem or a xylem.
Radioactive elements are useful for the study of the biological system because of the unique properties which they possess. For instance isotopes of radioactive elements can be used to label a specific molecule in order to be able to follow the movement of this molecule as it navigates through the human system.

Answer:
Low,cell,increase,decrease,volume,pressure,Renin,negative
Explanation:
It is synthesized when blood pressure is low or cell division is activated.It causes increase in resistance and decrease in fluid output(which helps to maintain blood volume and blood pressure) and an increase in blood volume(if fluid intake occurs). Consequently,blood pressure increases.This is aided by the release of both renin and aldosterone.As the blood pressure returns within its normal homeostatic levels,both renin release and angiotensin 2 synthesis are decreased by negative feedback.
1) Pulmonary Circulation:This is the process where
deoxygenated blood is carried away from
the right ventricle of the hearth while oxygenated blood is returned to the
left ventricle and atrium of the heart.
2) Heart: It is a muscular organ that pump blood through the blood
vessels of the circulatory system.
3) Systemic vain: <span>this is a vain that drain into the right right
atrium </span>
4) Physical exertion:It the expenditure of energy expended during physical
activity.
5) Vasoconstriction:It can be defined as the narrowing of the blood vessels which
result into contraction of the muscular wall of the vessels most especially
large arteries and small arterioles.
6) Vasodilation: This is when blood vessel is widening and result in
relaxation of smooth muscle cell within the vessel walls.
