Matter is made up of atoms and has mass. This is because for anything to be considered matter it must contain atoms and atoms must have mass.
Answer/Explanation:
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis. the energy storage molecule ATP and the reduced electron carrier NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
Osmosis is the movement of water from one region to another through a semi - permeable membrane. A hypertonic solution contains more solute than the cell.
In this case, the external salt solution is hypertonic because it contains a 8% salt concentration whereas the cell contains only a 0.9% salt concentration. As such, water moves out of the cell into the solution.
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.

Answer and Explanation: <em>Retroviruses</em> are harder to kill because they have a proteic capsule responsible for protecting their RNA. So, although the consequences of polyomaviruses can be more lethal, retroviruses are more difficult to kill.
To kill it, an<em> intermediate level desinfectant</em> is needed because it is an agent which can destroy lipid and some non lipid encapsulated viruses. Examples of those are Surfactants, which acts in the membrane lipids by binding, penetrating and losing the permeability, resulting in leakage of the internal contents of the cell or desinfectants containing Chlorine compounds, because chlorine can kill pathogens by breaking the chemical bonds in their molecules.
