Explanation:
When fats are used as a substrate in respiration, the RQ is less than 1 because the amount of oxygen utilised is always higher than the amount of carbon dioxide released.
Mass, because the student is measuring the weight
Answer:
The answer is 1) a chromosome
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
A ground source heat pump takes advantage of the naturally occurring difference between the above-ground air temperature and the subsurface soil temperature to move heat in support of end uses such as space heating, space cooling (air conditioning), and even water heating. A ground source or geo exchange system consists of a heat pump connected to a series of buried pipes. One can install the pipes either in horizontal trenches just below the ground surface or in vertical boreholes that go several hundred feet below ground. The heat pump circulates a heat-conveying fluid, sometimes water, through the pipes to move heat from point to point.
this system works during the winter due to it being a sub-ground energy source.
<h3><u>Answer;</u></h3>
Gap junctions
<h3><u>Explanation;</u></h3>
- Gap junctions allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.
- <em><u>Action potentials generated by the autorhythmic cells spread waves of depolarization to contractile cells through gap junctions. If the depolarization causes the contractile cells to reach threshold, they will in turn generate an action potential.</u></em>
