According to Darwin's Theory of Natural Selection, each generation produces more individuals than the ecosystem can sustain. However, not all individuals are identical and phenotypical variation exists.
Due to this variation, some antelopes are better at escaping lions, perhaps due to speed and/or stamina. Thus, the individuals that are slower and thus less fit will be killed and eliminated from the herd. The antelopes with heritable traits that makes them better suited to the environment, will escape and thus, survive and reproduce.
In Darwin's Theory predation is an evolutionary force.
Answer:
synapse is the connection of the axons of one neuron and the dendrites of another, myelin is the substance that protects the grey matter from the bony surface of the head for example, nucleus of a neuron is the main part of the nersous cell and neurotransmiters are the substances that make synapses posible ( and sometimes efficient)
The correct answers are: All of them.
- Runs off into the ocean;
The parts of the land that are close to the ocean, and are leaned towards it, especially if it is a more rocky landscape, when receiving precipitation, the water runs off directly into the ocean, though this is happening only on a relatively small area.
- Runs off into the streams and rivers;
Most of the precipitation on the land, ends up in the closest streams and rivers which increase their volume and carry the water further downstream.
- Enters the water table of groundwater;
Part of the precipitation managed to get through the soil and the rocks, and enters deeper, eventually reaching the underground reservoirs and filling them, thus contributing to the levels of the groundwater.
- Taken up from shallow soil by plants;
The plants need water for survival, so when there's precipitation, through their roots (some through their leaves), are taking water from the soil, thus spending part of it for their own needs.
