The answer is Walter Hess

Hess manipulated the diancephalon of the brain of cats by inserting metal rods in the hypothalamus regions of the brain, where the diencephalon is located, and passing electrical current through the rods to the brain region. He noticed that the cats, among other complex behavioral changes, would curl up and sleep.

In what zone is the ability to burrow and sustain changes in temperature and salinity important for an organisms' survival?
Sedbober [7]
The answer is C.
Living organisms that live in the littoral zones in the ocean are used to frequent changes in temperature and in the salinity of the ocean water. For an organism to survive in this environment, it needs to have adaptive features that will increase its survival. The littoral zone is divided into three zones, which are high, middle and lower littoral zones. Organisms living in high littoral zone have adaptive features that make them more adapted to desiccation due to the long hours of sunlight to which they are exposed. The organisms are usually exposed directly to the air or they can be enclosed in burrows.

Write a paragraph explaining how adhesion cohesion and capillary action all enable water to go from the roots to the top of the
poizon [28]

Adhesion, cohesion and capillary action enable water to go from the roots to the top of the tree due to its specific property.

<h3>How adhesion cohesion and capillary action move water to the top?</h3>

Capillary action helps to bring water to the upper parts from the roots but to a small distance due to strong gravity. In order to get water up to all the branches and leaves, the forces of adhesion and cohesion work together in the plant's xylem to move water to the upper body.

So we can conclude that adhesion, cohesion and capillary action enable water to go from the roots to the top of the tree due to its specific property.
