Cytokines are thought to raise the thermoregulatory set point to cause fever by stimulating the synthesis of the chemical mediator called the prostaglandin. These are secreted by specific cells found in the immune system. These are molecules involved in cell signaling that helps cells to communicate during immune responses and stimulate the cells to inflammation sites or infection and trauma sites. It stimulates synthesis of prostaglandin and then turnover in the thermoregulatory and nonthermoreglatory tissue. These molecules can exist into three forms which are peptide, glycoprotein and protein forms. These substances are classified in many ways because there is no present unified classification system.
C [2,3,1,4] is the correct answer
Answer:
a and d
Explanation:
<em>Among the products of meiosis listed, aB and Ab would be the recombinant types because recombinant gametes are gametes that are unique from the haploid gametes that made up the diploid cell. </em>
A and B alleles are on a particular chromosome while a and b alleles are on another chromosome. During the process of gamete formation/meiosis, the possible gametes are;
<em>While the first two gametes are parental (because they made up the original diploid cell), the last two gametes are recombinant gametes.</em>
Hence, from the list of options, aB and Ab are the only recombinant types.
<em>The correct options are </em><em>a</em><em> and </em><em>d</em><em>.</em>
