Gradient tool creates gradual blend between 2 or more colors. You can use gradients for backgrounds, design elements, layer styles but also when creating layer masks. Gradients are also useful to darken sky for example with nice gradual transition.
Gradients in Adobe Illustrator are a little tricky to figure out. Once your object is created, you need to click the gradient button at the bottom of the toolbar and then you can adjust the colors and angles using the gradient palette window and the gradient tool on the toolbar.
Passive transports such as diffusion and osmosis move down their concentration gradients.
It is a difference in pressure
Water potential gradients are influenced by factors such as solute concentration, pressure, and temperature. The movement of water from an area of higher water potential to an area of lower water potential is driven by these gradients.
Concentration gradients refer to the gradual change in concentration of a substance over space. This can occur within a single cell, between different parts of an organism, or in a surrounding environment. Cells often rely on concentration gradients to facilitate processes like nutrient uptake and waste removal.
Generation of proton gradients across membranes occurs?
Gradients
Yes, temperature can affect concentration gradients by altering the rate of diffusion of particles. Higher temperatures generally increase the kinetic energy of the particles, leading to faster diffusion and potentially reducing or smoothing out concentration gradients. Conversely, lower temperatures may slow down diffusion and lead to more distinct concentration gradients.
gradients are an example. Electric gradients are controlled by the transport of Na+ and K+ and H+, etc.
