Answer:
Photosystems PSI (P700) and PSII (P680) and photolysis of water releases energy
In the form of movement of electrons which is later extracted as ATP
Explanation:
On absorbing light energy electrons obtained from photolysis of water and those present in and those present in the reaction centres PSI and PSII move to the higher energy level and electron acceptors accept them. They then move down through the electron transport chain to the lower energy level during which ATP is produced which is a chemical form of energy.

Answer:
you can use the example of two magnets
Answer:
d = 0.84 g/cm³
Explanation:
Given data:
Mass of wood = 2.85 g
Volume of water = 20.0 mL
Volume of water + wood = 23.4 mL
Density of wood = ?
Solution:
Volume of wood = (Volume of water + wood ) - Volume of water
Volume of wood = 23.4 mL - 20.0 mL
Volume of wood = 3.4 mL
1 mL = 1 cm³
Density of wood:
d = m/v
d = 2.85 g / 3.4cm³
d = 0.84 g/cm³
