Answer:
Is an evolutionary sign in the specie
Explanation:
Trough the passing of time, the species changes little by little depending on the environmental conditions and the genetic traits that has from their parents.
Evolution is long term process in which the species start to adapt to their new environmental conditions.
Waves - Ocean waves can cause the coastline to erode. The shear energy and force of the waves causes pieces of rock and coastline to break off changing the coastline over time.
Answer:
They both conform to the basic laws of chemistry and physics.

Answer:
Option E
Explanation:
Complete question
A researcher is using a small molecule as an inhibitor to manipulate a signaling pathway. This inhibitor prevents phosphorylation and MOST likely targets a:
A) ligand-gated ion channel.
B) G protein-coupled receptor.
C) phosphatase.
D) G protein.
E) receptor kinase.
Solution
Receptor kinase is an enzyme that acts as a catalyst while transferring phosphate group to specific substrate thereby causing auto phosphorylation of tyrosine.
Phosphorylation occurs when receptor kinase binds to the ligands. Binding causes dimerization of receptor kinase which then phosphorylates tyrosine residues in the cytosolic domain.
The inhibitor molecule prevents phosphorylation therefore it must target the molecule responsible for causing tyrosine phosphorylation.
Hence, option E is correct
It has to be B, because we do not have all the same organs as worms, we have more organs and our brains cannot hold the same amount of information, because flatworms have different nervous systems all together.
So the answer is B.
