Have a primitive digestive system
Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
<h3><u>Answer;</u></h3>
Lithosphere
<h3><u>Explanation</u>;</h3>
- Lithosphere is the solid outer part of the earth which includes the brittle upper portion of the crust and the mantle. It is bounded by the asthenosphere below and the atmosphere above.
- <em><u>The pressure in the lithosphere is about 109 gigapascals or GPa. </u></em>
- <em><u>Asthenosphere has a pressure of about 18 GPa</u></em>
- <em><u>The mantle is a layer between the outer core and the crust, it has a pressure of about 149 GPa.</u></em>
