The statement is true. DNA replication process happen during the cell cycle.
Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
Answer:
There are three types of neurons are present i. e. sensory neuron, motor neurons and inter neurons.
Explanation:
Sensory neurons are the nerve cells which is responsible for sending the information from the sense organs such as tongue, nose, skin, ears, and eyes to the spinal cord and the brain while the motor neurons are responsible for the transportation of instruction from the brain and spinal cord to the muscles. The inter neuron helps in communication between motor or sensory neuron and the nervous system.
D is the answer. Mutations can cause MANY problems.
Answer;
-Neurotransmitters.
One of the first key terms she memorizes is neurotransmitters because these are the chemicals via which neurons communicate with each other.
Explanation;
-Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
-Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers.
