Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome
At the inner mitochondrial membrane<span>, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the </span>membrane<span>, through ATP synthase.</span>
Answer:
b. False
Explanation:
FOXP2 gene is required for language and speech development and is present in all animals. It is a transcription factor which encodes for a regulatory protein. Both modern humans and Neanderthals share FOXP2 gene which differs from chimpanzee version by two amino acids. Its the different regulation of the same gene which made modern humans more capable of using language and speech. Neanderthals did use language rudiments but not completely constructed languages. There might be other speech genes involved too which differed between modern day humans and Neanderthals but not FOXP2.
