What are electromagnetic waves that you can see?

<span><span>Radio waves: If our eyes could see radio waves, we could (in theory) watch TV programs just by staring at the sky! Well not really, but it's a nice idea. Typical size: 30cm–500m. Radio waves cover a huge band of frequencies, and their wavelengths vary from tens of centimeters for high-frequency waves to hundreds of meters (the length of an athletics track) for lower-frequency ones. That's simply because any electromagnetic wave longer than a microwave is called a radio wave.</span><span>Microwaves: Obviously used for cooking in microwave ovens, but also for transmitting information in radar equipment. Microwaves are like short-wavelength radio waves. Typical size: 15cm (the length of a pencil).</span><span>Infrared: Just beyond the reddest light we can see, with a slightly shorter frequency, there's a kind of invisible "hot light" called infrared. Although we can't see it, we can feel it warming our skin when it hits our face—it's what we think of as radiated heat. If, like rattlesnakes, we could see infrared radiation, it would be a bit like having night-vision lenses built into our heads. Typical size: 0.01mm (the length of a cell).</span><span>Visible light: The light we can actually see is just a tiny slice in the middle of the spectrum.</span><span>Ultraviolet: This is a kind of blue-ish light just beyond the highest-frequency violet light our eyes can detect. The Sun transmits powerful ultraviolet radiation that we can't see: that's why you can get sunburned even when you're swimming in the sea or on cloudy days—and why sunscreen is so important. Typical size: 500 nanometers (the width of a typical bacteria).</span><span>X rays: A very useful type of high-energy wave widely used in medicine and security. Find out more in our main article on X rays. Typical size: 0.1 nanometers (the width of an atom).</span><span>Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation. Typical size: 0.000001 nanometers (the width of an atomic nucleus).</span></span>

As the electrons pass through the electron transport chain between Photosystem I and II, they use their energy to pump _________
skelet666 [1.2K]

Answer:

protons /H+

thylakoid membrane of the chloroplast

acid.

Explanation:

This is chemiosmosis. And the ultimate aim is to synthesis ATPs. Proton Motive Force generated from the electron transport chain continuously pump protons(H+) from the stroma into the thylakoid membrane of the chloroplast,

The build up of  protons/H+ generated electrochemical gradients between this  space and the stroma.

Therefore proton/H+ diffused down the gradient into the stroma. The energy generated from the downwards diffusion is used by the ATPase synthase to synthesize ATPs from ADP and inorganic phosphate (Pi), to be used in Calvin Cycle for CHO, productions.

The protons/H+ pumped by PMF and  concentrated in the thylakoid memebrane is obtained from the  split of Hydrogen atoms  to electrons(e-) and H+. since pH is negative Log of [H+], therefore the space will be acidic from large concentration of H+/protons.

An aquifer has been compared to a sponge. Think about this analogy for a moment explain why the use of the word quotations “spon
wariber [46]

The word sponge is more appropriate to use than Underground river since an underground river can loose water while an aquifer cannot loose water, unless it is open-air and above ground. then the aquifer would slowly loose water due to evaporation from the sun.

What other structures of the cytoskeleton would show the same pattern of microtubules as a flagellum
pashok25 [27]

Answer:

<u>Cilia</u>

Explanation:

Cilia and flagellum are made up of microtubules.

Cytoskeletal filaments are structures which allow movement. In cilia and flagella, the cytoskeletal filaments are present in the form of microtubules and the primary work of these structures is to facilitate in movement.

Cilia is also present in mammals to facilitate the movement of fluids in cells.

Structurally, there is no difference between cilia and flagella. The only difference between cilia and flagella is in their lengths.
