Answer:
The flow of information within a neuron is intracellular signalling whereas the flow of information between neuron is inter cellular signalling.
Explanation:
- Central nervous system consist of 2 types of cell that are neurons and glia where neurons are the information processing structure in Central nervous system.
- A typical neuron consists of 4 parts called- cell body,processes,dendrite and axons.
- Cell body is the metabolic controlling center and from cell body, processes structure is extended which conduct signal flow to or away from the cell body.
- Dendrites receive the incoming signals and the outgoing signals to the other neurons are flow along with the help of axons.
- Neurons have an unique features of intracellular and inter cellular signalling.
- Intracellular signalling is proceed within the cells and inter cellular signalling is is transmitted between the cells.
- The communication that is generated between the neurons are achieved by synapses.This process is called as neurotransmitter.
Less kelp means less small fish and other stuff which means no food for the crab
When acid rain falls, aquatic animals get affected due to the spreading of acid rain which harms and destroy wildlife, it can reach to aluminum and then to soil, which basically destroys the ecosystem of the aquatic animals.
Answer:
d. Melting ice and expansion of heated water.
Explanation:
As the planet gets warmer, sea level rises.
The two major causes are melting of ice and expansion of seawater.
It is estimated that rising sea levels are caused
- One-third by melting of ice in Greenland and Antarctica
- One-third by melting of ice in mountains
- One-third by thermal expansion of the warmer water
a. is wrong. Increased precipitation comes largely from the oceans by the water cycle.
b. is wrong. Melting ice is responsible for only two-thirds of sea-level rise.
c. is wrong. Increased carbon dioxide levels increase the acidity of the water but have little effect on the volume.
