Answer:
Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.
Explanation:
Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
