Answer - Cellular Function
Reasoning -
First to point out All (Living) Things are (Made) Up of (Cells).
Second Cellular function or cells function have the same chemical makeup that perform a common function.
Answer:
These cells have a circular DNA molecules
Explanation:
Answer:
Explanation:
It's hard to tell. I was looking at a diagram representing the atmosphere. 50 miles is right on the edge of the Mesosphere. The temperature is about - 135 or so. It does climb up to about - 49 according to the Royal BC Museum.
The question is incomplete. The complete question is as follows:
Which of the following mutations is most likely to cause a phenotypic change?
A) a duplication of all or most introns
B) a large inversion whose ends are each in intergenic regions
C) a nucleotide substitution in an exon coding for a transmembrane domain
D) a single nucleotide deletion in an exon coding for an active site
E) a frameshift mutation one codon away from the 3' end of the nontemplate strand
Answer: D) a single nucleotide deletion in an exon coding for an active site
Explanation:
Deletion or insertion of a single nucleotide in an axon coding for an active site is called frameshift mutation.
The sequence of codons is read during translation, in order to synthesize a amino acids chain and form a protein from the nucleotide sequence. Frameshift mutations occur when the usual codon sequence is broken by the deletion or addition of one or more nucleotides. For example, if only one nucleotide is removed from the axon sequence during the RNA splicing process, then there will be a disrupted reading frame for all codons before and after the mutation. This may result in several incorrect amino acids being introduced into the protein. Disruption in protein sequence will cause phenotypic change.
Hence, the correct option is D) a single nucleotide deletion in an exon coding for an active site

Sea otters are a symbol of the beauty and diversity of marine life that can be found along the California coast.
They're also important to the health and stability of coastal marine ecosystems, hence they're considered critical species.
Sea urchins and other invertebrates that graze on giant kelp provide food for them.
Without sea otters, kelp forests and, with them, a variety of animal species that rely on kelp environments for existence would be destroyed.
Kelp forests also safeguard the coast from storm surges and absorb a significant amount of dangerous carbon dioxide from the atmosphere.
Sea otters are especially important since their health reflects the health of the coastal waterways of California.
