Which one is it ? i cant tell
Answer: 1500kg/m^3
Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.
Answer:
Light-dependent reaction of the photosynthesis takes place in the thyllakoid membrane of the chloroplast. It converts solar energy into the chemical energy (ATP and NADPH) which is then utilized in the light-independent reaction to fix carbon into glucose or food.
The correct order of events that take place during light-dependent reaction would be:
Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
↓
Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space.
↓
The concentration of hydrogen ions in the thylakoid space increases.
↓
Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
↓
ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
