Answer:

Biological evolution

Explanation:

<em>Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.</em>

There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.

The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.

There is an error in the above model.
ollegr [7]

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. <em>(a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.</em>

   

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. <em>These metabolic processes can either form it or break it.</em>

ATP provides energy to many different functions in the organism.

ATP means<em> adenosine tri-phosphate</em>. It is composed of adenosine (an <em>adenine plus a ribose</em>), and three phosphate groups.

<u><em>Note</em></u><em>: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).</em>

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as <em>phophoanhydrid bonds</em>, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.  

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

                      ATP  +  H₂O   ⇄   ADP  +  Pi  +  Energy

​

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

                 ADP  +  Pi  +  Energy   ⇄   ATP  +  H₂O

<em> (a) What is this a model of?</em>

  • This model represents the reversible ATP hydrolysis.

  • In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

  • When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

  • An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

  • ADP molecule is composed of adenine, ribose, and two phosphate groups.

  • Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

<em>(b) Explain how you would change the model to make it correct? </em>

  • What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.

  • In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

  • Added energy should be on the left
  • Released energy should be on the right

Which statement indicates one difference between the gene that codes for insulin and a gene that codes for testosterone in human
lozanna [386]

Answer:

hello your question lacks the required option below are the missing options

A) The gene for insulin is a sequence of five different molecular bases while the gene for testosterone is a sequence of only four different molecular bases.

B) The gene for insulin is replicated in vacuoles, while the gene for testosterone is replicated in mitochondria

C) The gene for insulin has a different sequence of molecular bases than the gene for testosterone.

D) The gene for insulin is turned ON in liver cells, but the gene for testosterone is not

answer : The gene for insulin has a different sequence of molecular bases than the gene for testosterone ( C )

Explanation:

The statement that indicates the difference between the gene that codes for insulin and a gene that codes for testosterone is ; The gene for insulin has a different sequence of molecular bases than the gene for testosterone.

Genetic codes are determined basically  by the four types of nitrogen bases contained in the molecules of the DNA ,
