A. Range 1.0-10uL
B. Range 2uL-20uL
C. Range 100uL - 1000UL
D. Range 10uL-200UL
Answers
A pipette of range 1.0-10uL is the most appropriate for taking a volume of 9 uL. So the correct option is A
What are micropipettes?
In the lab, micropipettes are used to transfer tiny amounts of liquid, typically less than 0.1 uL. In addition to other labs, they are most frequently employed in chemistry, biology, forensics, pharmaceutical, and drug development. There are various sizes of micropipettes commonly used in the laboratory.
Micropipettes vary in size and volume dispensed, and based on those two factors, they also need various pipette tips. Micropipettes aspirate liquid using a disposable pipette tip; take note that only the tip of the pipette comes into touch with the solution. For each sample, a fresh tip is used to avoid cross-contamination.
The quality of a pipette tip is the most important factor to consider. Whether one is searching for a filter, low retention, or gel loading tip, it should be made sure that the pipette tip will function as accurately and precisely as the micropipette. The purity of your pipette tips should be checked.
Therefore the correct option is A.

Burning plastics endangers flora, human and animal health, and emits hazardous chemicals into the environment, including dioxins, furans, mercury, and polychlorinated biphenyls (BCPs). Burning plastic releases extremely dangerous pollutants that greatly raise the risk of cancer, respiratory diseases, and birth problems.

why is the earths atmosphere likened to a greenhouse?
Answers
Answer:
That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. earth's atmosphere is like the glass in a greenhouse because sunlight streams through the atmosphere and heats the Earth. As the heat radiates up from the Earth's surface, some escapes into space. The rest of the heat is absorbed by gases in the troposphere and warms the air.Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a "feedback.") Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere.greenhouse gases in the atmosphere absorb some infrared radiation and re-reflect it back to earth. 6.

To produce starch, glucose molecules bond together and release a water molecule through which process?
O photosynthesis.
O cellular respiration.
O nucleotides.
O dehydration synthesis.
Answers
To produce starch, glucose molecules bond together and release a water molecule through dehydration synthesis. Therefore, option (D) is correct.
To produce starch, glucose molecules undergo a process called dehydration synthesis. During dehydration synthesis, two glucose molecules bond together, and a water molecule is released as a byproduct. This reaction is also known as a condensation reaction, as the joining of two molecules results in the formation of a larger molecule and the release of water.
In the case of starch formation, multiple glucose molecules link together through dehydration synthesis, creating a long chain of glucose units, which is the structure of starch. This process is essential in the synthesis of various biological molecules, including carbohydrates, proteins, and lipids, where smaller subunits are joined together to form larger macromolecules through the removal of water molecules. Therefore, option (D) is correct.
