Answer: Please see the explanation column for answers
Explanation:
A reflex arc is a nerve or neural pathway that controls a reflex action giving fast response to a stimulus without the conscious act of the brain. Here, the sensory neurons receive stimulation then synapses or connects to spinal motor neurons nerve cells which then connects to muscle cells acting as effectors.
Ranking the events that occur in the reflex arc in correct order gives
1st ---- A sensory receptor detects a stimulus
2nd---A sensory neuron conducts action potentials through the nerve to the spinal cord
3rd----- The sensory neuron synapses with an interneuron
4th----- The interneuron synapses with a motor neuron
5th------- The motor neuron conducts action potentials through the anterior root and spinal nerve to an effector organ.
Answer: Each Gamete will have 19 chromosomes
Explanation: because gametes contain HALF the chromosomes contained in normal diploid cells of the body, so you take half of 38, which is equal to 19.
Hope that helps!
Answer:
d. Two of the above explanations are correct.
Explanation:
A frameshift mutation is commonly known as a genetic mutation that occurs as a result of the indels such as the addition or removal of certain nucleotides in the sequence of a DNA that is indivisible by three. In the presence of addition or removal, the reading frame from the initial translation to a different one. Thus, the correct option is option d.
C. It is used for cell function or transformed to heat energy.
