How did Mendel use self‑pollination and cross‑pollination techniques in his experiments with flower color to observe the basic p

Answer:

Mendel carried out the inheritance experiment by cross pollinating the first fillia generation; the parent generation contained different colour of flowers. He then observed the patterns in the second fillia generation (F2).

Answer:

Pea plant flowers of two colors were used i.e., Purple and White. He observed the same ratio in both cases (3:1), in the self and cross pollination. This happens because of the assumptions in Law of Segregation and Law of Independent assortment. He concluded that the purple color is the Dominant and white in recessive as in both self and cross pollination procedures.

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

Rzqust [24]

The data have high precision but poor accuracy because of a systematic error. Thus, the correct option is A.

<h3>What is systematic error?</h3>

An error that is not caused by chance, but rather by a system-wide inaccuracy (in terms of observation or measurement).

The accuracy of a value refers to how close it is to its genuine value. An arrow's proximity to the bull's-eye center is an example. A measurement's precision refers to how repeatable it is. A systematic error has occurred.
