Answer:
The skull protects the brain from any direct damage and the vertebrae helps keep the nerves in the spine in place and protected from damage. So the central nervous system is protected by the vertebrae and the skull.
Answer:
In the crossing of two hybrid plants for the color flowers trait can be seen that the phenotypes are purple flowers and white flowers and in the descendants the phenotypes, genotypes and probabilities are purple flowers Bb (50%), purple flowers BB (25%) and white flowers bb (25%).
Explanation:
For the flower color trait, the dominant allele is purple (B) and the recessive allele is white (b). The planted cross shows two purple hybrid flowering plants (Bb) and the offspring can be seen in Punnet square:
<u>Crossing: Bb X Bb
</u>
Alleles B b
B BB Bb
b Bb bb
The results in the offspring are:
- <em>Plants with purple heterozygous flowers Bb 50%.
</em>
- <em>Plants with pure purple flowers BB 50%.
</em>
- <em>Plants with white flowers bb 25%.</em>
