What is meant by active transport? Concentration Gradients: A concentration gradient is the difference in the amount of a substance on either side of a semi-permeable membrane. It is energetically favorable for substances to move down their concentration gradient, from high to low concentration. ...
Whenevera living organism such as an animal responds to a stimulus in a way that ends up affecting its locomotion, the response is called Taxis. Animals are going to respond to a stimulus in two different ways and this means that there is going to be positive taxis on negative taxes. Wha...
What is meant by highest cell density ? Answer and Explanation: Highest cell density refers to when there is the highest possible concentration of cells in a culture. In a bacterial culture, the highest cell density will be when the bacteria have reached their maximum number. This will occur ...
As mentioned,passive processes do not use ATP but do need some sort of driving force. It is usually from kinetic energy in the form of a concentration gradient. Molecules will tend to move from high to low concentrations by the random movement of molecules. ...
is practically impossible, literally, and definitely unaffordable. Even if theoretically possible it would be so costly in resources it is a self-evident lunacy compared to the simple cheap abundant and sovereign solutions of nuclear energy. By contrast, the telatively weak energy of renewable ...
Tonicity is a measure of the concentration of solute in the environment compared to the cell. A hypotonic environment has less solute than the cell (and more water), a hypertonic solution has more solute than the cell (and less water), and an isotonic solution has the same amount of water...
We don’t have measurements, sure. But there is still evidence. Rising surface temperatureswilldrive the oceans to warm. But the ocean heat content lags the atmosphere temperatures by a good amount — it takes a while to heat them up. So, if the surface heats up a ...
A “virtual particle”, generally, is a disturbance in a field that will never be found on its own, but instead is something that is caused by the presence of other particles, often of other fields. Analogy time (and a very close one mathematically); think about a child’s swing. ...
is the event that the reported vote total for Maduro, González, and Other are all equal to the nearest integer of the total number of voters, multiplied by a round percentage with one decimal point (i.e., an integer multiple of ). is the null hypothesis that the vote totals were rep...
n i note that v v is the part of μ μ , if mutually recalculated to either mass or molar amount. water staying at higher gravitational potential has higher gibbs energy and chemical potential. similarly, in solution with solute concentration gradient, water in more diluted solution h...
