What effect does temperature have on rate of diffusion? What factors affect diffusion? Why does temperature difference increase the rate of heat transfer? Why can't polar molecules cross by simple diffusion? Why does diffusion occur in marine organisms?
So at stage 1 cancer cells mutate and diffusion dosn't occur. Althought posible it is unlikely that pacient die because all cells are not functionating. Before this happens cancer would have spread to other organs causing death. Even in stage 4 lung cancer there are some healthy lung le...
Examples of some of the more scientific ones are Stevens’s power law, the robustness of signal-detection theory’s rejection of high thresholds, the Rescorla–Wagner theory of learning, and the drift–diffusion model of response time and accuracy. Of course, each of these theories has limits,...
This result proved that bacterial inactivation mediated by TiO2 photocatalysis and PMS oxidation could be attributed to damage to the cell envelope and enhancement of membrane permeability, possibly even causing the diffusion and entry of molecules into cells during PMS treatment, and ultimately, E. ...
There is no direct supply of blood, lymphatics and nerves; nutrition relies on diffusion from the surrounding tissues. Based on the composition and function, it is possible to distinguish three types of cartilaginous tissues: hyaline, fibro- and elastic cartilage. Here we will focus predominantly ...
Step-by-Step Solution:1. Definition of Internal Respiration: Internal respiration refers to the exchange of gases (oxygen and carbon dioxide) between the blood and the body cells. It is a crucial part of the ov
Most insects depend upon passive diffusion to get oxygen to their cells and that is more effective at higher partial pressures of oxygen. Our lower concentration of oxygen today probably isn’t enough to enable such large insects, which is why they evolved to be smaller. Anyway, I had ...
The nonlinear terms α(σ) and β(σ) in equation (6) modulate the rates of glioma cell diffusion and proliferation according to oxygen availability. Under hypoxic conditions cell diffusion increases, while proliferation decreases, i.e. glioma cells become more migratory and less proliferative. ...
Why do molecules in solids not diffuse into one another? Why does diffusion occur in marine organisms? Why do capillaries need to be thin-walled? How does gas exchange occur in the lungs? How does smoking affect the alveoli in the lungs?
Why is diffusion important to cells? For what purpose does a cell use the energy from redox reactions in cellular respiration? Why is photolysis necessary for photosynthesis to occur? What factors affect cellular respiration? Why does O2 come from H2O in photosynthesis?
