Answer:
No it is not a proper waste disposal method
Explanation:
A man travelling in a train and throwing an empty packet off food on the platform and not inside the waste basket provided is definitely not a proper waste disposal. the best waste disposal method he would have used was throwing the waste in a waste bin
waste water management is the process of managing waste water emanating from homes or industries and controlling the negative impact this waste water would have on the environment. and one way to do that is the proper treatment of the water which entails removing contaminants from the waste water and converting the waste water into a useful effluent that can be used again ,

The answer is the first one because it doesn't create gases and, the third one doesn't even make any sense so its definitely not that one
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
