When you are on the roller coaster at Carowinds, your adrenal cells near the kidneys release adrenaline which then acts on the heart cells causing them to beat faster What is
this an example of?

A. Cell differentiation which causes the heart cells to become like the adrenal cells

B. Cell specialization because the heart cell has been changed and no longer acts like a heart cell

c. Cell signaling which acts upon the same type of cell that it is released from

D. cell signaling which is released by one type of cell and acts upon a different cell

D. Cell signalling which is released by one type of cell and acts upon a different cell

Explanation:

According to this question, adrenal cells near the kidney releases an hormone called ADRENALINE, which causes the cells of the heart to beat faster. This is an example of CELL SIGNALLING because chemical signals released by adrenal glands causes/triggers a response in the heart cells.

The chemical signal released by the adrenal cells is the ADRENALINE HORMONE, which induces a response in cells that are different from the cells of release (adrenal cells).

20 centimeters apart.

Explanation:

Tanya planted seedlings in her garden over the weekend.  The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart.  Tanya has a measuring tape that has values in centimeters.  As we know 1 meter = 100 centimeters . Therefore, 0.2 meter = 0.2 × 100 = 20 centimeters. So Tanya need to be planted 20 centimeters apart.
