Answer:
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
Babies, especially those who are at least 4-6 months old, have the tendency to explore objects by touching and holding them, and putting them in their mouth. By this time, it is very important to keep small objects out of their reach so that accidents can be prevented.
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
Answer:
a green pigment, present in all green plants
Explanation:
Answer:
1.7 x 107 nucleosomes.
Explanation:
The number of nucleosomes can be calculated by the following formula:
Nucleosomes = Genome size/ total number of base pairs.
Here, the genome size is 3.4×109.
Total number of base pair = number of base pairs in nucleosome core particle + linker DNA.
Total number of base pair = 146 + 50 = 196.
Number of nucleosome = 3.4×109 / 196.
Number of nucleosome = 1.7 x 107 nucleosomes.
Thus, the answer is 1.7 x 107 nucleosomes.
