What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?
dezoksy [38]

Answer:

<u>1. ATP - decrease </u>

<u>2.NADPH - decrease </u>

<u>3. sugars - decrease </u>

And    <u>True- Both ATP and NADPH are needed to make sugars.</u>

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants;  it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII).  PS II absorbs and moves the reaction center with light energy.  

  • H+, and oxygen,  are formed from a water molecule as it's broken apart.
  • From photosystem II, electrons are transferred to photosystem I.  
  • ATP is synthesized from ADP along with inorganic phosphate.  
  • To form NADPHH, H+ is added to NADP

If PS II no longer works,  there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of <u>CO2 with Ribulose 1,5-bisphosphate </u>(RuBP).

What are two likely results of mitosis in a mouse?
slava [35]

The two likely results of mitosis in a mouse are the renewal of epithelial tissues in the mouse’s large intestine and an increase in body size as the mouse matures (Options B and C). it is a cell division.

<h3>What is mitosis?</h3>

Mitosis is a type of cell division by which a parental cell generates two genetically identical daughter cells.

Somatic (body) cells are produced by mitosis, whereas germinal cells are produced by meiosis.

The primary functions of mitosis include the growth of an organism and the renewal of tissues.

Explain your experience in the area of planning, evaluation and coordination of human services programs, including strategic pla
mezya [45]

Answer:

My experience in human services programs was really stimulating and I learnt a lot about communication assets, which I think is the most important part of the job.

Explanation:

Working in humans services programs needs a certain skills that will help you to perform the job correctly. One of this skills is the ability of apply communication assets correctly, to know what to say in the correct moment.

Also, in order to have a successful activity, it is needed to make an organized planning, to evaluate and coordinate correctly. My experience in this process is that, no matter how much are you prepared, you must have several backup plans, because all people are different, and you don´t know what is going to surprise you in the next program. Always try to be ahead of any problem.

Some strategic plannings that you might need to coordinate such programs are to measure the time you will need for every activity, even approximately, this will help you to have a control over everything.

Also, try to have everything planned for at least three days before, if something unexpected happens, you will be able to fix it at time.
