Answer:
<h3>A. </h3>
Explanation:
<h3>Tutorial</h3><h3>Diffusion</h3><h3>Diffusion means that the net movement </h3><h3>of particles (molecules) is from an area of high concentration to low concentration.</h3>
<h3>Graph of the simple and facilitated diffusion taking into account the rate of uptake and the concentration</h3>
<h3>If the particles can move through the lipid bilayer by simple diffusion, then there is</h3><h3> no limit to the number that can fit </h3><h3>through the membrane. The rate of diffusion increases linearly as we add </h3><h3>more particles to one side of the membrane.</h3>
<h3>If the particles can only pass through protein channels, then the rate of </h3><h3>diffusion is determined by the number of channels as well as the number of particles.</h3>
<h3>Once the channels operate at their maximal rate, a further increase in </h3><h3>particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.</h3>
<h3>The cartoon illustrates several points about facilitated diffusion. The particles are more concentrated on one side of the membrane, and yet they can move in both directions. However, the net movement is from high particle concentration to low. If the number of particles gets so high on one side of the membrane that they</h3><h3> interfere with diffusion through the </h3><h3>protein channel, then we observe a limit to the rate of diffusion at the point of saturation.</h3>

<h3>Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a </h3><h3>concentration gradient; facilitated </h3><h3>diffusion moves materials with and against a concertion gradient. </h3>
Hello! The answer would be C; in order for a planet to support weather systems, it must have an atmosphere. Weather conditions such as thunderstorms, tornados, and hurricanes form there. Hope this helps! ^-^
Answer:
False, and brainly wants me to type 20 words but it's really straightforward
Answer:
This question is incomplete as it lacks the model, however, it can be answered based on general understanding of photosynthetic process. The answer is;
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Light dependent reaction, which is the first stage of photosynthesis, occurs specifically in the THYLAKOID of the CHLOROPLAST where the photons of light is absorbed by chlorophyll molecules (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis and the most useful way for communicating the role is by saying it provides the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
P and S waves travel at known velocities through the Earth. S waves are slower than P waves by a known amount. ... Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
