Answer:
Atmosphere, plant, animals, fossil fuels.
Explanation:
Carbon Is the essential elements needed for life.
Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.
Animals get carbon from plants after consuming plants.
During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.
Hence, sulphur and phosphorus are not gaseous biogeochemical.
Answer:
Meiosis
Explanation:
Meiosis is a cell division that results from sexual reproduction where half the chromosome of each parent cell contribute its genetic make up resulting in four haploid, genetically different gamete, cells. These are sex cells that determines the gender of a baby.
As part of this process DNA replication first occurs, followed by the two cell divisions, meiosis I and meiosis II, giving rise to four haploid daughter cells different from their parent cells.
Answer:
In gram staining, 95% ethanol is used to destain the gram-negative bacteria but gram-positive bacteria do not get destain because peptidoglycan layer in gram-positive cell wall does not allow crystal violet- iodine complex to come out of the cell wall.
Gram-negative bacteria do not have peptidoglycan cell wall and so crystal violet comes out of the cell wall by using 95% ethanol because ethanol dissolves the lipopolysaccharide membrane of gram-negative bacteria and allow the dye to leak out.
Therefore if I forgot to apply 95% ethanol than crystal violet dye will not come out of the lipopolysaccharide cell wall of gram-negative bacteria and it will appear violet under the microscope.
Answer:
Biodiversity is important to humans for many reasons. Ecological life support biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services
