Answer:

<u>a. the production of ATP</u>

<u />

Explanation:

Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths.  Here,

  • Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
  • Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
  • energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
  • These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
  • NADPH is generated from NADP+

Nitrates are made by converting ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). What do you predict the O2 levels in
AlexFokin [52]

Answer:

Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low

Explanation:

Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.

An elementary student believes a running car is an example of a chemical reaction because smoke comes out of a car. Is the stude
Darya [45]

Answer:

the student is incorrect.

Explanation:

a chemical reaction is defined as: changes in one or more substances caused by a reaction, that <u>form new and different substances.</u> Smoke coming out of a car would not really be classified as turning into a new substance, the smoke is still smoke.

The following DNA is being replicated and the origin of replication is in the middle of the sequence and marked with three stars
xxTIMURxx [149]

Answer:

5'GATCGTAA3'

5'ATTCTAGA3'

Explanation:

As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.

Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.

DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.

Negative impact humans have on the world's rainforest​
Dovator [93]

Answer:

The human impact on the Amazon rainforest has been grossly underestimated according to an international team of researchers. They found that selective logging and surface wildfires can result in an annual loss of 54 billion tons of carbon from the Brazilian Amazon, increasing greenhouse gas emissions.
