The brown and white stuff in concrete are usually aggregate materials like sand, gravel, or crushed stone that are mixed with cement and water to form the concrete. The brown color comes from the natural color of the aggregates used, while the white streaks could be from minerals or impurities present in the materials.
The main difference between rough ER and smooth ER is the presence of ribosomes. Rough ER has ribosomes attached to its surface, which gives it a rough appearance, while smooth ER lacks ribosomes. Rough ER is involved in protein synthesis and processing, while smooth ER is involved in lipid synthesis and detoxification processes.
The endoplasmic reticulum (ER) contains a high concentration of Ca2+ ions due to the presence of specialized pumps (such as SERCA) that actively transport Ca2+ into the ER from the cytoplasm. This accumulation of Ca2+ within the ER is crucial for various cellular functions, including protein folding and lipid synthesis.
The formula for erbium acetate is Er(C2H3O2)3.
Smooth endoplasmic reticulum (ER) is formed through the extension and branching of membrane tubules that lack ribosomes, in contrast to rough ER which has ribosomes attached to its surface. The smooth ER plays an important role in lipid synthesis, detoxification, and calcium storage within the cell.
The answer is no. There are no metals that begin with 'e', 'j' or 'k'

depends if youre talking about male female of it. kinda stuff... he is fresh=hann er ferskur (fersk+ur) ur is the part for the male stuff she is fresh = hún er fersk. it is fresh = það er ferskt so the main word is "fersk" and you add "ur" for male stuff or "t" for non male or nonfemale stuff hún=she hann=he er=is það=it
er....rub out stuff?
er hat braunes Haar
it is easy er to ship stuff
er you can hide under something to stop stuff gettingin ur way
Er, you can't.
It transports proteins and other stuff throughout the cell.
They cheated on each oth er.
The key unlocks the steering, stop stealing stuff Ni&&er!
You should be concerned with a bite from a brown recluse at anytime...they are poisonous and the bite can be fatal....ummm ER-quickly!
Erbium (Er) is the chemical element with the symbol Er and atomic number 68. It is a silvery-white, rare earth metal that is commonly used in nuclear reactors and as a colorant in glasses and porcelain.
