The folds in the stomach lining are called rugae. On these rugae, you will find a thin line of mucous which helps protect the stomach lining. The innermost layer is called Simple Columnar Epithelium.
<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.
(Pp is the purple flower with the unknown genotype, pp is the white flower)
First scenario:
Pp x pp
first generation: Pp Pp pp pp (two purple, two white flowers)
Second scenario:
PP x pp
second generation : Pp Pp Pp Pp (four purple flowers)
The answer to the question B which is the principle of dominance. Say the genotype of plant 1 is TT(tall, homozygous) and plant 2 is tt(short, homozygous). <span>T is dominant over t.
Crossing the two plants, we end with genotypes that all show Tt.
Since T is dominant it will show between the two, resulting in all tall plants.</span>
