Answer:
Diffusion
Explanation:
Diffusion is the process through which molecules in the cell are kept in balance with those outside the cell.
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.
Through the above mechanism, molecules having higher concentration in the cell move out of the cell and vice versa thereby maintaining the balance of molecules in and outside the cell.
Ayo i think the answer is B, 10 mg/l. bc you would label the respiration rate as R, we come up with a neat little formula: NPP = GPP - R. hope this helps, have an amazing day :)
Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.
There are 2 types of photoreceptors rods and cones they react to light in different ways.
Rods-
Respond to low levels of light and are primary responsible for night vision.
They are poor at detecting fine details in an image and are not involved in colour vision.
Cones-
Respond to high levels of light and are primary responsible for our vision in well-lit conditions.
They detect fine details and are responsible for colour vision.
