Answer:
Explanation:
The total solution formed after mixing the components will be
20 μl + 20 μl + 40 μl + 120 μl = 200 μl
The smallest size tube that will hold the entire reaction is:
Firstly convert 200μl to ml
1000 μl = 1 ml
200 μl = X
X = 200 x 1/1000
X = 0.2 ml
The smallest size tube (from the options provided in the question) is 0.25 ml.
The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.
The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
A Safety Data Sheet refers to a detailed information document prepared by a manufacturer of hazardous chemicals. It describes the physical and chemical properties of the product.
<h3>What is
Safety Data Sheet?</h3>
- A Safety Data Sheet refers to a detailed information document prepared by a manufacturer or importer of hazardous chemicals.
- Describes the physical and chemical properties of the product.
- A safety data sheet provides comprehensive information about a chemical, including its properties physical, health, and environmental hazards; and protective measures or safety precautions to be followed in handling, storing, or transporting materials.
- Safety data sheets inform users about product hazards, how to use the product safely, what to expect if recommendations are not followed, how to recognize symptoms of exposure, and what to do in an emergency .
- Safety data sheets provide information about chemicals and help users of those chemicals to make risk assessments.
- They describe hazards arising from chemicals and provide information on handling, storage, and emergency procedures in the event of an accident.

The rocky upper layer of the solid earth is called the "lithosphere". This rocky part includes the brittle upper portion of the mantle and also of the crust. It is bounded by the atmosphere above and of the asthenosphere which is another part of the upper portion of the mantle.
Answer:
The correct answer is The process of photosynthesis is energy storing because the process converts light energy into chemical energy which stored in the bonds of glucose.
Explanation:
During photosynthesis the light harvesting complexes absorb sunlinght and transfer that light energy to the reaction centre of photosystem.The photosystem then converts the light energy into chemical energy in form of ATP.
The ATP molecules are used along with NADPH to form glucose in the dark reaction of photosynthesis.
