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>

Answer:
The correct answer will be- to provide smooth surface at the ends of synovial joint.
Explanation:
Articular cartilage is the white smooth tissue present at the end of the bones which covers the bones at the joints. The articular cartilage is devoid of the nerves, blood vessels and lymphatics but is exposed to the biochemical environment.
The cartilage at the joint helps in the movement of the bones by reducing the friction produced by gliding or sliding of the bones over each other.
Thus, to provide a smooth surface at the ends of synovial joint is the correct answer.

Flexibility is relevant for everyone, not just cross-training athletes. It doesn't occur naturally, you have to train to get there. It is important for everything, not just running. </span>

Explanation:
Place theory is a theory of hearing which declares that our judgment of sound depends on where each element frequency generates oscillations along the basilar layer. According to the frequency theory, the pulse rate of the nerve vibrations of the hearing nerve communicates to the rate of a pitch, which enables us to identify its pitch. The complete basilar layer is stimulated by sound waves at various frequencies.
