Answer:
D
Explanation:
It is often like this: cell->tissue->organ->system
Answer:
Prediction is correct.
Explanation:
In the body, transportation of molecules can occur in different ways or mechanism.
An example is by facilitated diffusion.
It is a passive form of transport where carrier proteins shuttle the molecule such as glucose into the cell without using energy.
Glucose being a large molecule is shuttled by glucose carriers across the cell membrane into the cell by facilitated diffusion.
Therefore an increase in the number of glucose carrier means an increase in the rate of glucose transport.
The results will show our prediction was correct.
<h3><u>Answer;</u></h3>
A. <em>18 hydrogen atoms </em>
<h3><u>Explanation;</u></h3>
- <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
- <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
- Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
