What is the thickness of molecules?
a DNA molecule is 2 nm in thickness.
A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
The minimum thickness of the oil film should be equal to half the wavelength of light in the oil medium (because of phase change upon reflection). The formula for minimum thickness is: t = λ / (2 * n), where t is the thickness, λ is the wavelength of light, and n is the refractive index of the medium. Plugging in the values, we get t = 536 nm / (2 * 1.28) ≈ 209.4 nm. So, the minimum thickness of the oil film should be approximately 209.4 nm.
How big is a animal cell vacuole?
It is about 7-8 nm. Nm stands for micrometers. Don't ask, I don't get it either, but I guess mm was already taken by milameters when they invented MicroMeters, do they did it as nm instead of mm. bye buye
What is the thickness of DNA molecule?
The diameter of a DNA molecule is approximately 2 nanometers, while the distance between base pairs along the DNA molecule is approximately 0.34 nanometers. Therefore, the thickness of a DNA molecule is very small, on the order of a few nanometers.
Are ribosomes small or large?
70s in a Prokaryotic cell and 80s in an Eurakaryotic cell.
How thick is a cell wall?
about 10-80 nm
What is the thickness of molecules?
a DNA molecule is 2 nm in thickness.
State the approximate width of the cell membrane?
Cell membranes are normally 7.5-10 nm in thickness with two layers of lipid molecules containing protein molecules.
Compare the relative sizes of molecules plasma memberane thickness viruses bacteria organellesand cells using the appropiate SI unit?
Molecules are the smallest, typically ranging in size from 0.1 to 10 nanometers (nm). Plasma membrane thickness is about 7-8 nm. Viruses range from 20 nm to 400 nm in size. Bacteria are typically around 1-5 micrometers (µm). Organelles are larger, with sizes ranging from 0.2 to 10 µm. Cells are the largest, with sizes typically between 10 and 100 µm.
What is the unit cell of sucrose?
The unit cell of sucrose is a monoclinic unit cell with lattice parameters of a = 1.086 nm, b = 0.758 nm, c = 0.761 nm, and beta = 104.7 degrees.

What if the wall reflects light 400 to 500 nm and absorbs light 600 to 700 nm?
If the wall reflects light in the 400 to 500 nm range and absorbs light in the 600 to 700 nm range, it would appear to our eyes as a color that falls within the reflected range (blue-green) and not in the absorbed range. The absorbed light would not contribute to the perceived color of the wall.
What happens when light waves strike a black wall?
The reason the wall appears black is that it absorbs light in the visible spectrum (~400nm to ~700 nm in wavelength); otherwise, the wall is no longer black. A green wall reflects green light (~500 nm) but absorbs all else. ===========================
Which Apaches is named after the mescal plant?
Mescalero tribe in NM
Gram positive bacteria?
In 1884 the Danish physician Chriastan Gram developed the stain known as Gram stain with which one can distinguish the two cells of bacteria which is based on the difference of their cell wall. The gram positive cell stained purple whereas gram negative stained pink or red by gram staining. This is due to because gram positive bacteria cell wall consist of single 20-80 nm thick homogenous layer of peptidoglycan(murein)lying outside the plasma membrane. In contrast the gram negative cell wall is quite complex. It has a 2-7 nm peptidoglycan layer covered by a 7-8 nm thick outer membrane.
