Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.

I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
The correct answer is (A)
Burning of wood is a chemical change as new substance is formed during the burning of wood which is not reversible.
Now, what happened during the burning of wood?
In the case of burning wood, stored potential energy( in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion that requires oxygen. We can also say that combustion is change of potential chemical energy into kinetic energy in the form of heat.
Seeing a whole form, and then beginning to notice new details about individual parts, is an example of top-down processing.
Answer: Option D
<u>Explanation:</u>
When we start observing things the eyes take in the picture of all that is in the surrounding and when concentration is to be given to a particular object the brain at once perceive the information starting from the background narrows its concentration to that particular object.
In simpler terms, we don’t alone see a thing around us but we also get to feel the smell, hear the noise too. When we wanted to concentrate on a particular thing, say a person we think in the brain ,the memory stored correlate it to the particular thing and perceive it to be the person whom you are actually searching for. This information is narrowed down by top-down processing.
Sea otters are a symbol of the beauty and diversity of marine life that can be found along the California coast.
They're also important to the health and stability of coastal marine ecosystems, hence they're considered critical species.
Sea urchins and other invertebrates that graze on giant kelp provide food for them.
Without sea otters, kelp forests and, with them, a variety of animal species that rely on kelp environments for existence would be destroyed.
Kelp forests also safeguard the coast from storm surges and absorb a significant amount of dangerous carbon dioxide from the atmosphere.
Sea otters are especially important since their health reflects the health of the coastal waterways of California.
