An electron loses PE when it moves from a less electronegative atom to a more electronegative atom because it takes more energy to separate them.
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
Carrier proteins are involved in passive transport, moving solute molecules form one side of the membrane to the other. Option (A) is not true. <em>They increase the </em><em>speed of transport</em><em> across the membrane. </em>
<h3>Facilitated diffusion </h3><h3 />
- It is the transport of hydrophilic molecules that can not freely cross the membrane.
- Channel protein and many carrier proteins are in charge of this transport.
- When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one.
- When ions need to cross the membrane, the process depends on an electrochemical gradient
<h3>Carrier molecules</h3><h3> </h3>
- Carrier proteins move molecules from one side of the membrane to the other side.
- They do not need energy. They move solutes according to the electrochemical gradient.
- The carrier proteins have specific binding sites recognized by the transported molecules.
- When the proteins and the solutes get together, the carrier proteins suffer a temporal change in their structure.
- These changes allow the solute passage to the other side of the membrane.

</h3>
Options,
(A) They increase the speed of transport across the membrane. FALSE
(B) They concentrate solute molecules on one side of the membrane TRUE
(C) They have specific binding sites for the molecules they transport. TRUE
(D) They undergo conformational changes upon binding the solutes. TRUE
The incorrect option about carrier proteins is A. <em>Carrier proteins </em><em>Do Not increase</em><em> the </em><em>speed</em><em> of </em><em>transport</em><em>. They just make it possible. </em>

I don't what ur point,i might be incorrect(10%)
-food shortage
-living area
-different Animal behavior
It's D I took a test before on that and I passed
