Answer:
Describe how the students would use the apparatus to show that there were microorganisms present in the air in the laboratory. Remember to think carefully about experimental design and how to make the results reliable.
Title: using apparatus to know the presence of microorganisms
aims and objectives: description of presence of microorganisms in the air
materials and method: petri dish, agar, distilled water, hand gloves, nose mask, pipette e.t.c
methodology: pipette is used to measure the amount of water in a petri dish and placed outside where hands can not be touched for 24 hours, after then the water is taken to the lab and agar is added for bacteria growth, after 24 hours, if the microbial growth is seen on the cultured plate, then it shows that the air is contaminated with microorganism which mixes with water when exposed to air
precaution: i ensured personal protective equipment are worn throughout the experiment.
conclusion: it is ascertained that air is contaminated with microorganism as a result of the above performed experiment
Explanation:
The answer is passive transport does not require energy and moves materials from areas of relatively higher to lower concentration.
Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.
Acid drainage, especially acid mine drainage is the process whereby water combines with the sulfide minerals like pyrite which is iron plus sulfur (high in sulfur) to produce sulfuric acid (iron plus sulfur plus oxygen so oxidation of the sulfide like pyrite is part of the process) which is deleterious to the environment so where mine waste contains pyrite then it must be isolated and neutralized with say limestone or submerged in water to prevent the development of sulfuric acid.
