Why does the reduction of the dye DCPIP work best using the chloroplasts whose outer envelopes have been damaged during preparat
Stolb23 [73]

Answer:

NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer  electrons  in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+

These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid  intramembranes.

Outer membrane covers  the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of  the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.

The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope. 

Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.

Thus   the rate of reduction of DCPIP is faster.The  color changes to colorless increases when reduced , from blue color.

arlik [135]
<span>Looking at the two species' DNA would be a good place to start. If there are a number of similarities in their genotypes, then there would be a good chance that the two would also share some type of a common ancestor. This would be evidence that there was some type of selection that took place that necessitated two different species that shared a number of traits and features.</span>

Which of these is NOT a requirement or influence on chemical cycling of inorganic nutrients in a natural ecosystem?
OLga [1]

Answer:

The correct answer is option d.

Explanation:

Chemical cycling illustrates the systems of concurrent circulation of elements between other states, compounds, and substances, and then return to their original state, which takes place in space, and on many objects in space comprising the Earth.  

Chemical cycling of the nutrients (inorganic) is needed to maintain the conservation of nutrients on Earth. The chemical cycling of nutrients in a natural system requires a pool for the elements, the activities done by human beings, the biotic community and its food chains, and an exchange pool from which producers extract their nutrients. All the mentioned factors are associated with affecting a chemical cycling in exception to the input of geothermal energy.

Answer:

Nucleus

Explanation:

It is enclosed by a nuclear membrane perforated by numerous pores. It regulates the activities of the rest of the cell. It contains chromosomes which carry the hereditary materials. One or more densely staining bodies called nucleoli is present in the nucleus. It is site for synthesis of ribosomes
