It depends on the membrane, but generally water is the only one that will move across unaided. The rest are too large.
Most meteors aren't bright enough to be visible in daylight, or even in bright moonlight. But there are a few seriously large meteors each year which are visible in daylight.
The visible portion of electromagnetic spectrum is called the visible light and is the electromagnetic wave with the wavelength between 380 - 740 nm.
The planet Saturn has visible rings formed mostly of chunks of ice, ranging from microscopic size to the size of large boulders.
No. They are large and visible to the unaided eye.

In large amounts, yeast is visible to the unaided eye, but a single yeast plant is not.
Objects large enough and close enough to see with the unaided eye are referred to as macroscopic, which is the opposite of microscopic.

No they dont
Hydrogen bonds hold cellulose molecules together in bundles large enough to form fibers..
No you would see an entirely different vista. Most of the stars you can see from earth would not be visible to the naked eye from the galactic core, and they would also be lost in a blaze of glory of the core suns. From within a planetary atmosphere you probably would not be able to see stars even at night, due to the ambient light. The core suns are packed about a quarter of a light year apart.
neurons
neurons
A neuron has a large cell body that contains the nucleus, threadlike extensions called ­dendrites, and an axon. The dendrites carry impulses toward the neuron's cell body. The axon carries impulses away from the cell body. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A neuron can have many dendrites, but it has only one axon. An axon, however, can have more than one tip, so the impulse can go to more than one other cell.Axons and dendrites are sometimes called nerve fibers. Nerve fibers are often arranged in parallel bundles covered with connective tissue, something like a package of uncooked spaghetti wrapped in cellophane. A bundle of nerve fibers is called a nerve.
Macroscopic is when something is large enough to be perceived or examined by the unaided eye, where as microscopic is where you need an eye aid to help examine it. Example: For a rock you could examine it with your eyes without the use of a microscope, it would be macroscopic. The microscopic cell beside it, which you cannot see without a microscope, would be microscopic.
