How does water get from soil to where it needs to go? How do plants absorb water?

goldenfox [79]

Explanation:

plant absorbs water through the root by

the osmosis process

concentration of root is more than water

so. a pressure is developed in the wall of root

by the which water goes up and reaches to the

What are the precautions that should be token when using a photometer? please help me

Maksim231197 [3]

Answer:

PRECAUTIONS FOR USING A SPECTROPHOTOMETER :

1 . By allowing the lamps and electronics to warm up

2.By cleaning up any spills inside the cuvette compartment

3.By carrying out the set-up procedure in the correct order

4.By ensuring that %T or transmission is used as appropriate

5.By closing the door to the cuvette compartment before reading the result

6.By performing calibration checks after set up

7.By wiping fingerprints and spilt sample off the outside of the cuvette before measuring

8.By using the correct wavelength

PRECAUTIONS FOR USING A FRAME PHOTOMETER:

1. Do not move or Carry the unit when in use or connected to the mains electricity supply

2. There should be sufficient time for the chimney to cool before handling

3. Do not use acetylene with the flame photometer

4. Over adjustment of the fuel valve will cause excess flame

Do not position the product so that it is difficult to disconnect from the mains supply

5. Do not cover the chimney whilst in use.

6. Do not block or obstruct ventilation slots /airways

7. Do not operate or handle any part of the product with wet hands

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.
