My answer -
Organisms that reproduce sexually do so via the production of sex cells, also called gametes. These cells
are very different for the male and female of a species. In humans,
male sex cells or spermatozoa (sperm cells), are relatively motile.
Female sex cells, called ova or eggs, are non-motile and much larger in
comparison to the male gamete. When these cells fuse in a process called
fertilization, the resulting cell (zygote) contains a mix of inherited genes from the father and mother. Human sex cells are produced in reproductive system organs called gonads. Gonads produce sex hormones needed for the growth and development of primary and secondary reproductive organs and structures.

When a same experiment is done by scientists from two different fields, it is very likely that the conclusions would be different. The main reason for this is that both of them will have different view and methods to come to the conclusion, as their focus is on different things, or at least the approach is different.

Throwing daily waste/garbage in the landfills is the most popularly used method of waste disposal used today. This process of waste disposal focuses attention on burying the waste in the land. Landfills are commonly found in developing countries. There is a process used that eliminates the odors and dangers of waste before it is placed into the ground. While it is true this is the most popular form of waste disposal, it is certainly far from the only procedure and one that may also bring with it an assortment of space.
This method is becoming less these days although, thanks to the lack of space available and the strong presence of methane and other landfill gases, both of which can cause numerous contamination problems. Landfills give rise to air and water pollution which severely affects the environment and can prove fatal to the lives of humans and animals. Many areas are reconsidering the use of landfills.
