The phreatic zone or water table
Answer:
TRUE
Explanation:
The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.
The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.
The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.
The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.
There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.
However, the basic nerve cell is very similar in all animals.
In the lysogenic cycle, a virus integrates its DNA into the host's DNA, and its DNA is replicated when the host DNA is replicated.
The correct answers is : <span>They allow the exchange of gases between cells in the leaf and the external environment
The stomata are small openings that can be found on both the upper and the down part of the leaf and they are connected to the plant's vascular system.
These openings enable the plant to get rid of excess water in the form of vapor and to take CO2 from the atmosphere that is essential for the process of photosynthesis. </span>
