Answer:
The correct answer is:
D. Gene A is assorting independently of genes B and C, which are linked.
Explanation:
According to the text it is possible to deduce that the first allele of gene A appears with allele of gene B or C half of times. On the other side alleles of genes B or C appear at the same time in 14.4% of the cases. This information shows how A is and independent variable and how B and C are related as they appear together as well.
Answer:
Simple diffusion is when the particles travel through the cell and facilitated diffusion is when the molecules travel through the cell.
Answer:
The correct answer is (amino) met - lys – phe
Explanation:
3' G C C G A U G G A U G A A G U U U U A A A G U A A U A G C A A U G G A G G A C 5'
Write the mRNA in opposite or reverse order as 5' to 3' and then start with AUG codon.
Write the mRNA in revers order as 5’ to 3’ and starts with AUG codon.
5’-CAGGAGGUAACGAUAAUGAAAUUUUGAAGUAGGUAGCCG -3’
mRNA—5’AUG-AAA-UUU-UGA-AGUAGGUAGCCG -3’
Peptide: (amino) Met-Lys-Phe-STOP
Answer:
The answer is Norepinephrine.
Explanation:
Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.
Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.
I hope this answer helps.
