Answer;
B) increased number of chromosomes in the offspring.
Explanation;
-Cross over is a process that takes place during meiosis. It occurs when homologous chromosomes pair up and the segments of chromosomes are exchanged between non sister chromatids, resulting to recombinant chromosomes.
-The process causes genetic variation among organisms due to exchange of genetic material. In addition to increased genetic variation, cross over may results to the appearance of new phenotypes in the offspring. Also cros-over mutations may cause harmful mutations.
It is called a voluntary response if it does pass through the brain ( a part of the central nervous system) but if it doesn’t pass through the brain it is called a reflex arc.
Well, it takes 3 moles of oxygen to completely burn 2 moles of methyl...
<span>So for every 2 moles of methyl, you need 1.5 times as much oxygen (3 divided by 2) </span>
<span>That makes your ratio 1 : 1.5 </span>
<span>You need 1.33 moles of methyl so you multiply both sides of the ratio by 1.33 = 1.33 : 1.995 </span>
<span> 1.995 moles of oxygen are needed</span>
