Answer:
Municipal solid waste (MSW), is the type of waste that contain items related to everyday use.
Different countries have different ways to manage their Municipal solid waste (MSW), some of the techniques used by developed and under-developed countries are as following:
Developed Countries: Example of developed countries are Norway, Australia and USA et-cetra. Disposal methods used are:
- Composting - decomposing organic solid wastes into humus.
- Sorting - In this method garbage is sorted or dumped in bins on the basis of their type such as paper, colored glass and white glass et-cetra.
Both: Disposal methods used by both the countries are:
- Incineration - disposal of waste through burning
- Landfills - MSW is placed in landfills apart from human contacts.
Under-developed Countries: Example of under-Developed countries are India, Afghanistan and Algeria et-cetra. Disposal methods used are:
- Open uncontrolled dumping - throwing waste in open
- Waste picking - waste pickers pick recyclable waste.
Hence, there are some common and some different ways to dispose MSW in developed and under-developed countries.
Answer:
The correct answer is - reproduce rapidly.
Explanation:
In the insects such as cotton whitefly can develop a resistance to a variety of pesticides by surviving a small population from each pesticide or insecticide treatment.
Such populations reproduce rapidly to transfer the gene that is mutated or the change it adapted for survival to next generations and pass the resistance to the insecticide. If the use of an insecticide is repeatedly and in large quantity, there are chances to develop resistance to a larger population.
Answer:
Option (1).
Explanation:
Action potential may be defined as the change in the cell potential that helps in the transmission of the nerve impulse. The resting membrane potential of the cell is -70mV.
The depolarization phase of the cell has membrane potential towards more positive. After the depolarization phase, the sodium channels are closed and potassium influx occurs that causes the re-polarization of the cell. This activity of the re-polarization is not the consequence of the closing of the inactivation gates.
Thus, the correct answer is option (1).
