Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
Answer:
Explanation:
The purpose of the dihybrid cross was to determine if any relationship existed between different allelic pairs
To determine if one trait could affect the inheritance of another trait
The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
- Mass of Sara;

- Distance from ground;

- Acceleration due to gravity;

- Gravitational potential energy;

<h3>Gravitational Potential Energy</h3>
Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;

Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.
