Answer:

<u>The bacterial cell because it has the largest surface-to-volume-ratio.</u>

Explanation:

The rate of diffusion in and out of a body depends on surface area to volume ratio. The higher the ratio the greater the rate of diffusion and the lower the ratio, the lower the rate of diffusion.

This implies that small organisms like the bacteria cell expose a large surface area to the surrounding when compared to big organism cells. Therefore, small organisms depend on diffusion as a means of transport of foods, respiratory gases and waste products.

Large organisms, in addition to diffusion have trasnport systems to increase the efficiency of diffusion.

We can confirm that Ms. Bronner is using a token economy to encourage the rule-following in her classroom.

<h3>What is a token economy?</h3>

This is a method of positive conditioning in which a token of some sort is given as a prize to reinforce positive behavior, with the idea that these tokens may then be exchanged for even greater reinforcers once a certain level is reached.

Therefore, we can confirm that since the methods being described in the questions perfectly correspond to this definition, Ms. Bronner is using a token economy to encourage the rule-following in her classroom.

Kay [80]

Answer:

genomic imprinting

Explanation:

Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.

Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
