The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
The upper most layer is the canopy
Answer:
Salt water I think. Mostly oceans right?
Explanation:
Head foot and visceral mass
Most of the mollusks species are gastropods. The body of the mollusk is made of shell and fleshy part. The fleshy part is divide into foot and visceral mass. Foot is a distinct feature of mollusk. They use it mainly for locomotion. The visceral mass involves the organs for circulation, digestion and other important processes in living organism. The visceral mass has two external flaps of tissue called as the mantle. It secretes calcerous shell and encloses a mantle cavity.

1. Evaporation - During this process, surface water turns into water vapor. This is done by the transfer of heat energy. Water absorbs this heat energy and turns into its gaseous state.
2. Condensation - Water vapor rises into the atmosphere and is changed into water droplets. When gas is chilled, it turns back into a solid state. These water particles that form in the atmosphere then come together to form clouds.
3. Sublimation - Ice directly converts into water vapor without first converting into a liquid. This process accelerates when the temperature is low or pressure is high.
4. Precipitation - It is the result of evaporation and condensation. Precipitation describes any liquid or solid water that falls to Earth as a result of those two processes. It includes rain, hail, snow, sleet and a bunch more.
5. Transpiration - When precipitation happens, the soil absorbs some of the water. While in the soil, the roots of plants will take in the water and push it towards the leaves where it is used for photosynthesis.
6. Run Off - This happens as a result of precipitation, so it is again, technically not a process. As water pours down, it leads to runoff. This is the action of water running over the surface of the Earth. As water runs over the ground, it can displace the topsoil with it and move minerals along lakes, seas and oceans.
7. Infiltration -
This last process happens when water does none of the things stated above after precipitation. Sometimes, some of the water will move deep into the soil. Avoid the plants, avoid evaporation, avoid runoff, everything. The water instead seeps down and increased the level of the groundwater table. It is called pure water and is 100% fresh and drinkable.
