Answer: Reverse the position of two cells from opposite poles as the blastula stage allow development

Explanation:

An experiment should be performed, this experiment will help to discover the interactivity that exists between cells before reaching the fetal period. The experiment ought to also influence the location of the cells.

Assume that you are a national official with the power to set policy for controlling environmental mercury pollution (Core Case
Kazeer [188]

Answer:

The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution.  Policy:

  • Ban the incineration of waste
  • Require that coal-burning companies remove mercury from the coal
  • Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
  • Require that products containing mercury be labeled as such.
  • Set up programs that will recycle batteries and mercury-filled products.
  • Set up education programs that will help inform people about mercury pollution.

This policy works by addressing the ways to prevent and control mercury pollution.

Three problems that could result from implementing this policy:

  • Backlash from coal-burning companies.
  • It could take a while before we completely shift away from using coal.
  • Some of the programs that can be set up in this policy can be too expensive to set up and maintain.

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).
