Answer:

The correct answer is - due to the law of segregation.

Explanation:

In the given case the genotype of Rr and as we know R is a dominant characteristic for round seeds and r represents the recessive allele for wrinkled seeds in a pea plant. So if a plant has Rr in its genotype it means it is a phenotypically round pea plant due to dominance in this heterozygous case.

The law of segregation states that two alleles of a gene of a specific trait will be distributed randomly and there is an equal chance of each allele to end up in the gametes, similarly in this case both alleles can be segregated to gametes and it is a random process.

The degree to which chromatin is compacted greatly affects its accessability for ____________ , and thus, gene expression.

iVinArrow [24]

The degree to which chromatin is compacted greatly affects its accessibility for transcription, and thus, gene expression.

<h3>What is Transcription?</h3>

This is the process which involves copying a segment of DNA into RNA in organisms.

When chromatin is condensed, DNA becomes less accessible for transcription factors and vice versa which was why it was chosen as the most appropriate choice.

nignag [31]

Answer:

A) Temperature

Explanation:

Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.

In this question given, the data is portraying the Temperature versus Photosynthetic rate. This means that the experimenter is testing to see the effect of varying temperatures on the photosynthetic rate. Hence, the TEMPERATURE is the independent variable because it is the variable being changed.
