Answer: b) Cell walls prevent cells from dying in hypertonic conditions.
A cell wall is a layer located outside the cell membrane found in plants, fungi and bacteria. The cell wall of bacteria is made up peptidoglycan which gives bacteria a structural support. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of it's shape.
A hypertonic solution has a higher concentration of solute and lower concentration of water than the cell. This will cause a net movement of water out of the cell and into the solution by osmosis. Although cell wall is a semipermeable membrane but it will not be able to prevent the water loss. This will result in dehydration of bacterial cell, and cell may die.
Therefore, cell walls does not prevent bacterial cells from dying in hypertonic conditions.
Sphagnum is found in bogs and swamps and forms peat, a source of fuel.
Answer:
reducing gases of the greenhouse, reducing plastic products, reuse renewable energies.
Explanation:
Nowadays we have plenty of problems because of the greenhouse gases, the main effect is the big hole of ozone in Earth atmosphere, the main effect of this hole is that the temperature is increasing, so the oceans temperature increases some species will dye.
Plastic products since they have a very long term life in Earth is very difficult to our planet to biodegrade, so the accumulation in soil and water we can see the effects in the big islands of treasure that is formed in oceans, and how the aquatic animals are eating them instead of food.
Renewable energies are other example of how we can use other sources of energy instead of petroleum products, in this way we avoid air pollution because of the fossil fuels burning.
