Answer:
Explanation:
In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.
Diffusion happens in living systems for example it explains the movement of carbon dioxide in leaves. Plants absorbs water from the soil by osmosis through their roots hair cell. Animals molecules enter the body cells and waste products are removed.
Answer:
The heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
Explanation:
When Eric-palces some room temperature strawberries into the freezer, he is changing the temeprature of the strawberries. When the strawberries are in the room tempertaure, they are absorbing certain amount of heat.
When they are placed in the freezer they are releasing the heat to the environment and this leads to condition called as phase change. Due to this phenomenon, the heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
Answer:
Impairment of photosynthesis
Explanation:
The major effect of oil spilage is that it impairs or hampers photosynthesis.
Photosynthesis is the process where green plants manufactures their own food in the presence of sunlight and water.
Water is denser than oil. Therefore, oil floats on the surface of water. Oil on water surface acts as a blanket to sheild plants away from receiving direct sunlight. Sunlight is very important during photosynthesis.
In the absence of sunlight, plants are unable to manufacture their food.
They are also unable to receive carbon dioxide from the environment.
