Answer:

The sample size of the  animal  was too small , not large enough to conclude that the effects of the chemicals on Salamander was the actual cause of toxicity and  weight loss.

It is possible that  the drop in weight may be as a result of other environmental factors; agitation from background noise and  sudden exposure to new environments,, fluctuation in  temperature of the  surrounding environments , lack of  feed supply or others  

However, if there was many salamanders available; and most reacted to the chemical exposure in the same  way then it can be concluded that, toxicity of the chemical is  the causative factor.

Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply.
Crank

Ans.

Chromatin molecules are made up of DNA and histone proteins. Modification of chromatin structure include covalent, post-translational changes in histone proteins, present in chromation. Acetylation and methylation are two important histone modifications that affect structure of chromatin molecules.

Acetylation involves addition of an acetyl group to histones that increases transcription of DNA by loosen the association between DNA and nucleosome.

Methylation involves addition of a methyl group to histones that results in condensation of chromatin molecule and thus, decreases transcription of DNA.

Both acetylation and methylation are reversible processes.

Many chromatin modifications are genetic, means they can pass from one generation to another generation, called epigenetic modifications.

Thus, options B), C), D), E), and F).
