Answer:
C
Explanation:
Humans are the most evolved species in the phylogeny
Phylogeny in biology pertains to the evolutionary history or development of a group of organisms, such as a tribe or a racial group.
Human happen to be at the top of this evolutionary history
Answer: Hydrocarbons enter the cell by dissolving in the lipid bilayer of the membrane.
Explanation:
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.
Answer:
a system, or a group of interconnected elements, formed by the interaction of a community of organisms with their environment.
Explanation:
Introns stands for intervening sequences within a gene.
Explanation:
Introns are the nucleotide sequences within a gene which are intervening but noncoding regions on an RNA transcript which is spliced before the RNA translation to protein
Introns do not code amino acids for protein synthesis. They break the gene sequence in the DNA strand.
The introns form a large chunk and interfere with the protein coding of exons, hence are removed by splicesomes through splicing at the splice junctions.
Improper splicing of introns lead to faulty protein formation
