<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.

<h3 />
Composting helps to remove organic waste from the environment.
Compost requires some species if organisms which help to degrade the waste matter.
Some compost species which can be used to treat the problem of waste disposal include earthworms, slugs, beetle and fruit fly.
Therefore, the composition of compost species for breaking down compost-able garbage is: earthworms, slugs, beetle and fruit fly.

Answer:
Option A.
Explanation:
Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.
Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function
Vestigial structures no longer carry out any function.
