Answer:
spheres of Earth are represented in a tropical rainforest are
1. BIOSPHERE
2. HYDROSPHERE
3. LITHOSPHERE
4. atmosphere
Explanation:
Biosphere :The biosphere includes all life on Earth - plants, animals and humans. Most of what is studied in Life and Living is about the biosphere. The biosphere also includes life in the oceans, and under the soil. For example bacteria living on decaying plant material and the smallest sea creatures and plants are part of the biosphere.
Hydrosphere: The hydrosphere includes all water on the planet - the oceans, lakes, rivers, groundwater, rain, clouds, glaciers and ice caps. About 70% of the surface of the Earth is covered with water. The oceans contain most of this water, with only a small portion of it being fresh water. All the water on Earth forms part of the hydrosphere.
Atmosphere:The atmosphere includes all the air above the surface of the Earth all the way to space. All the gases that are present in the air are included in the atmosphere. Most of the atmosphere is found close to the surface of the Earth where the air is most dense. The air contains 79% nitrogen, less than 21% oxygen, and a small amount of carbon dioxide and other gases
Lithosphere: The lithosphere includes the Earth's crust and the upper part of the mantle. All mountains, rocks, soil and minerals included in the Earth's crust are part of the lithosphere. Even the seafloor is part of the lithosphere, because it is also made up of sediments of sand and rock.
Answer:
Types of variation in genetics
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
other answer
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
