<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>

Answer:
Rough endoplasmic reticulum differ from smooth endoplasmic reticulum by the presence and absence of ribosomes in their surface.
Explanation:
Rough endoplasmic is named so because RER contain ribosomes at their surface and due to the presence of ribosomes rough endoplasmic reticulum play an importnt role in protein synthesis or translation.
Whereas smooth endoplasmic reticulum does not contain any ribosome in its surface.smooth endoplasmic reticulum helps in the biosynthesis of lipid and steroids along with detoxification of toxic compounds.
Answer: Though the answer were not given, the complementary RNA strand is 5'UCCGAGGUC3'
Explanation: RNA is a single stranded nucleic acid produced from DNA. Four bases are usually found in DNA and they include adenine, Uracil, cytosine and guanine whereas adenine, thymine, cytosine and guanine are found in DNA. In RNA base pairing, wherever adenine is found in the DNA template strand, uracil occurs in the RNA strand, wherever thymine is found in the DNA template strand, adenine occurs in the RNA strand and anywhere cytosine occurs in the DNA template strand, guanine occurs in the RNA strand. This means that adenine pairs with uracil, cytosine pairs with guanine and thymine pairs with adenine.
The answer is C) Increase genetic variation and breed plants to contain the wild variety.
Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.
<h3>Plant cell vs animal cell</h3>
From the observations, both cells are eukaryotic. This is because:
- cell X has lysosomes which are only found in eukaryotic cells
- cell Y has a nucleus which also peculiar to eukaryotic cells only
Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.
Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.
Generally, plant cells have larger vacuoles than animal cells.
