Genetic variation is advantageous because it enables some individuals and, therefore, a population, to survive despite a changing environment.
- they are both found in the same place
- they are both passed down to newer generations
- both of them can determine your traits
In the biology lab, you have just finished a dissection, you should do all of the following EXCEPT Wrap your specimen in the original wrapping and give to your instructor to dispose of. Thank you for posting your answer here. I hope it helps.
Asexual reproduction is a process wherein cells produce genetically identical offspring.
Since asexual reproduction is when offspring are produced from a single parent, the offspring are identical to the parent. Sometimes, asexual reproduction is called cloning. Cloning is the production of two identical genetic copies from a single parent cell.
Answer:
The first stage of neural communication, <u>conduction</u>, is the movement of the signal within a single neuron. <u>Transmission</u> is the movement of a signal between neurons.
Explanation:
The neuron is the irreplaceable and highly specialized unit of the Nervous System, since it is the basic element in the conduction of the nerve impulse. The primary function of the neuron, conceived in its uniqueness, is to receive information and transmit it, once it has been processed.
The nerve impulse only spreads in one direction. When a neuron is stimulated, electrical changes originate that begin in the dendrites, pass through the neuronal body, and end in the axon, this is known as conduction. At the point where an axon and a dendrite are associated, it plays a very important role in the transmission of the impulse from one neuron to another and in the functioning and coordination of the nervous system in general, since the neurons do not act in isolation. The neurons are arranged in such a way that the axon endings of one are connected with the dendrites of the next neuron, but there is no physical contact itself, but a microscopic space that separates them, in addition there is a neurotransmitter substance that allows the flow of nerve impulse under those conditions, said substance is acetylcholine. These transmitting molecules diffuse through the synaptic cleft and chemically transfer the signal, from the axon of a neuron to the receptor neuron.
