Answer:

B

Explanation:

Carbon atoms usually have a Lewis electron configuration of 2.4. To gain a stable electron configuration of 2.8, they usually form covalent bonds with other atoms such as another carbon and hydrogen. Carbon does not form ionic bonds because it would require much more energy for the atom to gain 4 electrons or lose the 4 electrons to achieve electron configuration. This is why carbon is a significant atom of life due to its versatility in how it bonds with other atoms including other carbon atoms. It can also form single double and triple bonds giving rise to many compounds, with the same elements, but with different properties.

charle [14.2K]
Long ears have to be dominant:

If this IS true then these would be your 'parents':

L = long ears
l = curly ears

LL x ll

If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.

What facts can you compile that would support a theory that multicellular eukaryotes developed from unicellular prokaryotes?
Delicious77 [7]

Answer:

Multicellular eukaryotes evolved from unicellular prokaryotes by the process of endosymbiosis

Explanation:

All living beings have evolved from three groups of animals closely related with each other.Domains: Archaea,bacteria and eukarya.the archaea and bacteria are unicellular organism surrounded by single cell water and  and coiled stand of DNA. Eukaryotic cells are more complex and with a linear  strand of DNA which is in the nucleus. Actually mitochondria which had evolved from a free living bacterium which was swallowed by another cell. The host cell benefited from the chemical energy that mitochondria produced and mitochondria in turn is benefited to be inside the protected environment. Mitochondria is the main organelle which the multicellular eukaryotes with unicellular prokaryotes.

When chromatin is condensed gene expression is likely taking place?
Setler [38]

<span>Gene expression is taking place when chromatin is less condensed. Highly compacted chromatin is not accessible to the enzymes involved in DNA transcription, replication and repair because transcription is being inhibited or inactive. Therefore, looser configuration permits transcription or gene expression to take place. </span>
