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

What conclusions can we draw from the lab about photosynthesis and cellular
GuDViN [60]

Answer:

Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration forever unless something interrupts.

Explanation:

Photosynthesis and cellular respiration are two distinct and opposite metabolical processes undergone by living cells. They are opposite processes because one utilizes the products of the other as reactants.

Photosynthesis is a unique process to autotrophic organisms like plants. It is the process whereby plants synthesize their food in form of organic molecules (glucose) by combining Carbondioxide (CO2) and water (H2O) in the presence of sunlight.

The overall equation of photosynthesis is as follows:

6CO2 + 6H2O ------> C6H12O6+ 6O2

On the other hand, cellular respiration is the process whereby living cells obtain energy (ATP) by breaking down food molecules (glucose) using oxygen to produce carbondioxide (CO2) and water as products. The overall equation is:

C6H12O6 + 602 -----> 6CO2 + 6H2O

Based on the lab experiments, it can be concluded that Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration because photosynthesis recycles/reuses the products of cellular respiration, which are C02 and H2O while cellular respiration recycles/reuses the products of photosynthesis, which are C6H12O6 and O2. This process occurs naturally in the environment and will continue to do so unless something interupts.

Option B is incorrect because light energy from the sun powers photosynthesis while option C is incorrect because photosynthesis transforms light energy to chemical energy while cellular respiration transforms chemical energy to thermal energy.
