When placing a red blood cell in any hypertonic solution, there will be a movement of free water out of the cell and into the solution. This movement occurs through osmosis because the cell has more free water than the solutio
Answer:
The correct answer is option C. "the slow rate at which diffusion occurs over large distances".
Explanation:
Circulatory systems help to maintain homeostasis by compensating from the slow rate at which diffusion occurs over large distances. Circulatory systems accelerate the rate of oxygen diffusion and allows that it reaches every part of the body, including the most distant areas from the heart, the organ that pumps blood to the whole body.
Answer:
Oxygen loving bacteria are accumulated only in two areas in the slide, at its ends, areas rich in oxygen
Explanation:
A prism decomposed the light in different wavelengths between 400 and 700 nm. Plants only absorbed some wavelenghts, one that peaks at about 440nm and the other around the 660 nm, as their particular Chlorophyls used to work.
Electrons from a reaction center from a photosystem (PSII) containing a particular chlorophyl , are launched to higher levels of energy when this is excited by light wavelength (680 nm) and travel by a molecular chain to an acceptor of electrons, forming ATP. To refill the electrons in the reaction center, H2O is hydrolyzed, and their e- reach the reaction center. In this step O2 is also produced.
A second photosystem (PSI) is also excited from another similar reaction center, whose electrons are used to produce reducing power in the form of NADPH. This photosystem I also acts as acceptor of the electrons coming from PSII
