HOPE THIS HELPED!!!!!!!!!!!!! XDDDDDD

Answer:
The cellular process of diffusion does not require cellular energy to reach equilibrium.
Osmosis uses a selectively permeable membrane to reach equilibrium.
Explanation:
The process of diffusion in which energy is not required is called passive transport.
Osmosis is also a type of diffusion in which materials pass through a semi-permeable membrane in the cell. Semi-permeable membrane allows certain solutes to pass through such as salts and nutrients etc.
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
