Answer:
behavioral separation
Explanation:
The separation leading to the speciation of the two groups of killer whales would be considered a behavioral separation.
<em>Behavioral separation or isolation is a form of separation that occurs between two groups of individuals (that use to be of the same group) as a result of preference for a particular behavior or set of behaviors.</em>
The preference for the behavior eventually leads to the two groups becoming separate species, a form of speciation known as sympatric speciation.
The answer is eukaryotic cells
Answer:
1. telescope
2. astronomers
3. radio waves
Explanation:
A telescope allows one to magnify what they're looking at to see it closer than it actually is. Astronomers are those that study planets, stars, and other celestial bodies in space. Modern telescopes have the ability to detect radio waves from astronomical objects that emit them from far away. This allows us to see what we normally would not be able to.
Answer: This situation states that the cells has two different receptors on them.
Explanation:
The particular neurotransmitter can have different receptors on them. An (EPSN) excitatory postsynaptic potential causes change in the membrane potential of the postsynaptic cell which tends to open the channels for the positively charged ions inside the cell.
This leads to the activation of the ligand sensitive channels.
In case of the inhibitory postsynaptic potential ( IPSP) makes the neurons less like to generate any action potential.
So, for the same neurotransmitter, one cell X shows excitatory response and other cell y shows inhibitory response.
