<span>The answer is a) mitosis, meiosis. Body cells may produce additional body cells by means of mitosis. Organisms that reproduce sexually produce gametes by means of the process of meiosis. Mitosis is a process which results in two identical cells being produced through division, whereas meiosis results in the splitting of a cell to create two genetically different daughter cells. </span>
Descending tracts are the pathways by which motor
signals are pass through from the brain to lower motor neurones. Thus, all
the neurones within the descending motor system are classed as upper motor
neurones. The lower motor neurones then directly innervate muscles to produce
movement. Their cell bodies are found in the cerebral cortex or the brain stem,
with their axons remaining within the CNS.
Answer:
0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.
Explanation:
From the dilution equation:
<em>Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).</em>
In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL
v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L
v1 = 0.0556 mL
This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,
10 - 0.0556 = 9.944 mL
<em>Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.</em>

Answer: Prey for the rabbits would decrease greatly; there would be less food for the frogs and voles, so their populations would decrease. This means less food for the foxes and hawks.
