The most surprising thing about the universe is that it we don’t know when it will end and it could end at any point in time. The most surprising fact about our galaxy is that it would take around 26,000 years to get out of it.
Number 3 is microorganisms.
Answer:
D
Explanation:
An oil boom helps contain the oil so that it is easier for them to skim it off of the water. They aren't meant to clean up oil, only to contain the oil since it does not sink or mix with water.
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
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.
