Explanation:
crossing over is a process that happens between human organs chromosome in order to increase general diversity. during crossing over part of one chromosome is exchange with another. the result is a hybrid chromosome with a unique pattern of genetic material. gametes gain the ability to be genetically different from their neighbouring gametes after crossing over occurs. this a loss for genetic diversity which will help cell participate in survival of the fittest and the evolution.
Answer:
This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation. To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.

Answer:
I live in a rural area which is surrounded by mountains and valleys. Near my home there is small forest area where there are hundreds of thick tall forests, algae and many other photosynthetic plants.
The atmosphere of that forest is very clean and refreshing because there is alot of oxygen being produced there due to alot of photosynthesis being done by all the lush green plants there.
Due to photosynthesis, carbon di oxide that is an environmental pollutant is maximum used by the plants and maximum. Oxygen is produced as a result of photosynthesis.
This causes the environment of not only that forest but my whole village very clean and fresh to breath. We are living a healthy life where there is a less prevalence of diseases or infections that are caused by environmental pollutants like Bronchitis, Lungs infection, neural disorders etc.
Therefore, even if there is not such an area near your home, we would suggest you to plant more trees in your backyard that will make the environment of not only your home but your area very fresh and clean.
Hope it help!
The answer is the first one ( True )
The answer is; C & E
Building a dam alters the water regime down the dam. The dam also affects fish migration along the river, alters the transportation of sediments by the river downstream, and changes temperatures within the local environment of the dam. These changes, however, the subtle effect the ecosystem around the dam and down the river. The potential energy of the water held by the dam is, however, high and used to produce more electricity.
