Answer:
Green house gases like carbon dioxide, carbon monoxide, carbon tetra chloride, methane, sulphur dioxide, nitrogen dioxide, etc .. are responsible for Global warming and Chlorofluorocarbons and nitrides of oxygen are responsible for Ozone layer depletion.
Explanation:
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).
Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
Answer:
Replication and Distribution of DNA during Mitosis. ... This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
Answer:
True
Explanation:
Milipedes belong to a class of organism known as diplopoda which have double foot. Thus, millipedes have two legs per segments. They usually have two pairs of jointed legs. The double legged segments have formed out of two single segments fused together
On the other hand , a centipedes has only one pair of legs per segment.
Thus the given statement is true.
