You are examining the DNA sequences that code for the enzyme phosphofructokinase in skinks and Komodo dragons. You notice that t

he coding sequence that actually directs the sequence of amino acids in the enzyme is very similar in the two organisms but that the surrounding sequences vary quite a bit. What is the most likely explanation for this?
A. Coding sequences are repaired more efficiently.
B. Coding sequences are replicated more efficiently.
C. Coding sequences are packaged more tightly in th e chromosomes to protect them from DNA damage.
D. Mutations in coding sequences are more likely to e deleterious to the organism than mutations in noncoding sequences.
E. Recombination between skink and Komodo dragon DNA occurred recently

Answer:

The correct answer is D.

Explanation:

Mutations in coding sequences are more likely to be deleterious to the organism than mutations in non-coding sequences.

Mutations in coding sequence is more harmful because they end up mutating the protein coding region of the DNA , which alters the function of proteins.

These mutations may cause some harmful genetic disorder or end up causing cancer.  That is why mutations  in coding sequences are more harmful to the organism than mutations in non-coding sequences.

Which of the following correctly describes the order of events occurring during a sympathetic nervous system response?
meriva
<span>Stimulation of thoracic or lumbar spinal regions; impulse reaches chain ganglion; acetylcholine release</span>. Acetylcholine is released if the synapse happens in the sympathetic ganglion, if the synapse is in post-ganglionic neuron, norepinephrine is released.

7. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
nydimaria [60]
Kinetic energy = 0.5*M*V^2 

 Q7-
 
0.5*3*(2^2)= 6J

Q8a- 

0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.

Q8b-

at the max height, all the kinetic energy is converted to potential energy, 

gravitational potential energy is = M*g*h

that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:

First ball:
2kg*9.81(g)*10m = 196.2J

Second ball
4kg*9.81*10m= 392.4J

The second ball has more potential energy

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms
Delvig [45]
<h3><u>Answer;</u></h3>

A. <em>18 hydrogen atoms </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
  • <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
  • Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
