Answer:

Both parents are heterozygous for the trait. They must be carriers of the recessive gene that codes for blue eyes.

Explanation:

Let us assume that the dominant gene codes for brown eyes while the recessive gene codes for blue eyes. We can suggest that both parents are carriers of the recessive gene. They both express brown eyes because they also have a dominant gene that codes for brown. Clark inherited one recessive allele from each parent, so he expresses blue eyes. The couple has a 75% probability of getting a brown-eyed child, while the probability of getting a blue-eyed child is 25%.

What happens during the lytic cycle?
Veseljchak [2.6K]

In the lytic  cycle, a virus that has invaded and  entered a  cell takes over the cell's replication mechanism. The virus makes viral DNA and viral proteins.

The virus then lyses (breaks open) the cell membrane, allowing the newly  produced viruses to leave the now disintergrated host cell to infect  other new cells.

The lytic cycle is considered  the main method of viral replication. It is even more common than the lysogenic cycle. It has helped scientists understand better how the immune system responds  to pathogens.

The correct answer is B. She was measuring a rate of change.

Explanation

A linear graph is a type of graph that contains a series of data represented by points joined by linear segments, which allow you to quickly check the change in the trend of the data. Therefore, inline graphs quantitative variables are usually used to see their behavior over time. According to the above, Anjuli had to use a linear graph to express the information in the graph more clearly, because the data that he was using in his graph were quantitative variables. Also, she wanted to express the respiration rate of the yeast per minute. According to the above, the correct answer is B. Ella She was measuring a rate of change.
