Answer:
cell membrane
mitochondria
lysosomes
ribosomes
Explanation:
Cell membrane is the boundary of animal cell which is responsible for the intake of nutrients from outside environment of the cell. Cell membrane is a semipermeable membrane which take nutrient through a process of diffusion and active transport. Mitochondria is also called power house of the cell in which glucose molecule is broken down and energy is released. Lysosomes is an important organelle of the cell which is responsible for the collecting and removal of waste material from the cell through cell membrane. Ribosomes helps in the production of proteins and enzymes needed by the cell for different activities.
Answer:
Washing hands daily and wear clean clothes.
Explanation:
Washing hands daily and wear clean clothes are the methods which prevent the spread of microorganisms and when exposed to microorganisms in the laboratory, we will have to use disinfectant in order to remove the microbes so that the solution or reactions are safe from the contamination. There are many methods such as sterilization as well as using chemicals is responsible for the removal of microorganisms.
Answer:
For example, air with a large amount of water vapor is less dense than dry air because the water molecule has less mass than either an individual nitrogen or oxygen molecule. Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth's surface also forms large global wind patterns
