It can be concluded from the experiment that wire B has a higher resistivity compared to wire A. Furthermore, Resistance could be inversely proportional to heat therefore, the higher the temperature of the metal when current flows through it, the lesser its resistance to current.

Neurons in the ______ , control motor reflexes.
yan [13]

Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.

The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.

Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.

The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.

  • Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.

  • Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.

  • Interneurons can be excitatory or inhibitory.

Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.

3. Put the boiled leaf in boiling tube containing alcohol <u>extract (ethanol) chlorophyll ethanol dissolves Lipids in cell membranes.</u>

4. Return to leave to the hot water <u>soften the leaf and allows penetration of </u><u> </u><u>i</u><u>odine</u>

5. Remove leaf and perform the iodine test

Explanation:

<em>starch is white powdery substance consisting of glucose which is used by plants as food the percents of starch in leaves evidence enough of the process a photosynthesis being carried out in leaves as the formation of starch necessitates photosynthesis</em>.

A. Which form of nitrogen in the soil is NOT usable by organisms?
Colt1911 [192]

Answer:

A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things

B) it can not be used because it most be converted or, ’fixed’  to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.

C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.
