which statements, there is nothing
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:
В. It is possible that your body weight is within the appropriate range, but your body composition is not.
Explanation:
The "BMI" or <em>"Body Mass Index" </em>is used in order to know whether the weight of a person is within the normal range. However, <em><u>it's not a real indicator for a person's body fat composition in the body.</u></em>
For example, a person within the normal weight may look healthy because his BMI is within the standard range; however, he may actually be fatty on the inside if his body composition will be checked. Another example are the weightlifters. They may seem heavy on the outside and their BMI are above the normal range; however, their body fat composition is low. So, this means they're healthier though they're overweight.
