The given question is incomplete as it does not have the options which are:
A. commensalism
B. mutualism
C. parasitism
D. predator-prey
Answer:
B. mutualism
Explanation:
The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.
When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.
In the given question, the shrimp provide a safe habitat to the goby fish whereas goby fish protect the shrimps from the predators. Since both the species are benefitting each other therefore the species form a symbiotic relationship.
Thus, Option-B is the correct answer.
Answer:
7
Explanation:
amount of protons in atom is equal to amount of electons. if given neutrons, then it might be diff than protons since there are isotopes
Lithosphere
13 major plates
Asthenosphere
Explanation:
The surface or lithosphere of the earth is broken into about 7 major plates that floats on the liquid asthenosphere.
The analogy above describes the theory behind plate tectonics.
- The crust and the rigid part of the upper mantle forms the lithosphere.
- The lithosphere is broken down into series of pieces called plates.
- There about 13 plates on earth surface.
- The rigid plates moves on the weak asthenosphere below as a result of convection currents.

Answer:
The correct answer is - all of the above.
Explanation:
If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.
It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.
