Answer: In diagram B, the magma here is observed to be within the crust and could not come out to the surface. This signifies that the hot, rising magma, suddenly cooled down forming a huge block of mass which is considered to be an intrusive igneous body. It can be a batholith, lacolith or a pluton. This type of body is formed due to the cooling and the consolidation of hot magma.
Answer:
Option D, the "biological ladder"
Explanation:
The food chain is the network of organism in which all are dependent on each other for their food, energy source and survival.
The circle of life depicts the time frame starting from origin of a life form till its death and the intermediate stages.
The tree of life basically determines which organism has evolved from which other organisms.
The biological ladder represents the development of species from simple form to a much complex form.
Hence, option D is the right metaphor
Answer:
The correct answer is - when action potentials trigger the release of neurotransmitters.
Explanation:
Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.
These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.
I believe the answer to this is B
