Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level.

The three types of counselling sessions are as follows-
a) Directive counselling - This counselling is mainly focused towards the senior members of the societies . Here the problem is analysed and then the solution is formulated. It is applicable in both stressful and non stressful condition.
b) Non -directive- This counselling is mainly focused towards the junior members of the society. The juniors have the problem of their own and they want to have solutions as well of their own. This counselling helps them to get mature. It is conducted in a non stressful situation and is mainly focused to resolve attitude problem.
c) Collaborative Counselling:
Here both the counselor and the person whose counselling is being conducted gets benefited.
*Blood flow is regulated in all three types of blood vessels through constriction and dilation.
*Contraction of blood vessels slows blood flow, while relaxation of blood vessels, or dilation, allows free flow of blood.
*Muscle fibers control the constriction and dilation of vessels. In the capillaries, rings of muscle called capillary sphincters control blood flow.
*The directional flow of blood in the veins is controlled with valves , which prevent backward blood flow when closed, and allow blood to flow only toward the heart when open.
Vasoconstriction and vasodilatation allow blood vessels (arteries and veins) to control blood flow and thus control the blood pressure. This is possible because of the smooth muscle cells that surround the vessels. The contraction and dilatation of those muscles is controlled by chemical signals (e.g. norepinephrine constricts the vessels, while NO dilates them).
Plant cell has chloroplasts, vacuole and cell wall...
animal cell doesn't have any of these...
Since we wish to test the null hypothesis that gender and personal goal are independent. Under the said null hypothesis, the expected number of boys that would select "be good at sports" would be the same more or less with the girls that would select "be good at sports". The difference in their means would be set to zero for this null hypothesis.
