The body system that directly provides for this demand is the circulatory system. When you exercise, the circulatory and muscle system cooperate, in order to meet the increased needs for strength and energy. The circulatory system involves the network which delivers blood to every part of your body. This flowing of blood ensures that the tissues are oxygenated and rich in necessary nutrients. During exercise, more blood flows to and from your muscles, in order to deliver the necessary amounts of oxygen to complete the aerobic respiration.
The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels. Less use of fossil fuels means lowering greenhouse gas emissions and others.
Answer:
The six codons for arginine are the following:
GCA, GCG, GCT, GCC, TCT, TCC
A) Considering the individual bases in each codon, three mutations are possible at each base position. Hence, 3 × 3 × 6 = 54 mutations are possible.
B) Considering the mutations at the 3rd base: 3 × 4 + 1 × 2 = 14 of these mutations are silent mutations.
C) Lysine codons are the following:
TTT, TTC
There are two possible mutations that can give a lys codon.
Hope that answers the question, have a great day!
