Answer:
A. Thalamus
Explanation:
There are two large ovoid organs called the thalamus, which form most of the lateral walls of the third ventricle of the brain. A variety of receptors transmit signals from the thalamus to the cerebral cortex. Thalamus is anatomically situated adjacent to the midline third ventricle in the brain.
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
I believe it's the first one.
Tissue typing is a screening process in which cell markers in a donated organ or tissue are identified so that they can be matched to a recipient with similar cell markers. This has become more important in recent years because of the number of organ transplants
I think it is B because a cladogram shows how species are related AND also shows the evolution between them.
