Answer:
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).
The cell keeps molecules balanced inside and out hope i was right have a very nice day
Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.
<span>Gravity assists the marble, leading to conservation of energy. The
stored energy is release as momentum, the output of energy is constant.</span>
If science is to be defined at,
science is a systematized body of knowledge. Science is where the organized set
of facts were obtained and is used as a tool, model or paradigm to gather such
evidential data. Science is not a fact but an existential body in which comprises
the study of the anatomy and physiology of a certain object by the means of
observation, hypothesis, experimentation, interpretation and conclusion of the
gathered facts. Or what others would describe the scientific process.
