Answer:
<em>B. Different crops could be grown on the same land.
</em>
Explanation:
Crop rotation is the process of growing different plants in the same land according to the season. Various kinds of plants require various sorts of supplements from the soil.
Changing crops on a regular basis enables the land to stay rich in nutrients, since not the majority of similar nutrients are being utilized each season. Crop rotation likewise fights against the powers of soil erosion. It also helps to improve the stability of the soil by shifting back and forth between harvests with profound roots and those with shallow roots.

<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.
Answer:
The phosphate head of the phospholipid is hydrophilic because it is polar (having charge), and thus readily dissolves in water which is a polar solvent. The hydrocarbon chain tails of phospholipid are hydrophobic because they are nonpolar (uncharged), and thus remain undissolved by water. These hydrocarbon tails have an affinity for each other, orienting themselves to face each other in water, forming the hydrophobic …
