A hand washing sink in the break room is not an appropriate location for washing hands after working with human material in the laboratory.
A vital part of laboratory safety is hand washing. In fact, this 20-second method is regarded as one of the most crucial steps utilized to stop chemicals, radioactive materials, and microbiological agents from infecting you and the area around you.
Even though gloves should be used when handling hazardous items, adequate hand washing should still be done on a regular basis. If you don't wash your hands right away after taking off your gloves, germs could spread to your mucous membranes and infect you, or they could contaminate neighboring surfaces and endanger other lab workers.
Every laboratory that uses chemical or biological agents must have access to at least one sink for hand washing, ideally close to the room exit. To prevent contamination, the sink must be cleaned frequently, and soap must be available for hand washing.

Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
Answer: The correct answer is- Solar energy, carbon dioxide, and water.
Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.
This phase occurs in the thylakoid membrane of chloroplast.
During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.
This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.
In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.
Thus, solar energy, carbon dioxide, and water is the right answer.
I am pretty sure that your answer is C or D. Im not sure between the two which. Sorry.
