Answer: The question is not complete as options are not complete , the remain part are;
A. 3.7 years, photosynthetic bacteria.
B. 3.7 years cyanobacteria.
The correct option is
3.7 billion years old, cyanobacteria and stromatolite.

This is because cyanobacteria is the oldest fossil to exist and they have been in existence for about 3. 7 billion years. These cyanobacteria photosynthesized because they have thread like chlorophyll filament, they produce food through the process of photosynthesis which is needed for their survival and they release oxygen as bye product.
Answer:
Temperature is the measure of the average energy of motion of all the particles present in a substance because particles of a substance moves due to the presence of kinetic energy.
Explanation:
Kinetic energy is a type of energy that is present in an object due to its motion. When temperature of a substance is increased, the particles absorb heat energy from surrounding environment and starts motion. This motion of particles due to the absorption of heat energy is called kinetic energy. So that's why temperature is considered as a tool to measure average energy of a motion.
