These are proteins. Transmembrane proteins span the entire membrane.
Reproduce like mad!
A cell wall is typically made of cellulose in plant cells and peptidoglycan in bacterial cells. These tough, rigid structures provide support and protection for the cell.
True. Many organisms are mad up of only one cell. Nearly all Bacteria, most Protists, and some Fungi only have one cell for each organism.
Well because the elodea leaf is a plant cell the flexibility can be factored down to the support cell skeleton which is mad up of microtubles which have enough resistance and spring in them enabling them to allow the cell to hold their shape but allowing it to bend. another factor can be of the medium in which the organelles reside in which is the cytoplasm (a starch fluid that transports things around with cytoplasmic streaming such as proteins the endoplasmic reticulum also helps in the moving of things through out the cell)
At the cellular level, mad cow disease (BSE or bovine spongiform encephalopathy) is caused by a mis-folded protein that causes other copies of the same protein to mis-fold as well. These mis-folded proteins (called prions) do not function and cannot be broken down by the cell, so they accumulate like so much cellular junk in the cytoplasm until the cell dies from inability to function. The clinical signs at the whole animal level are caused by the deaths of nerve cells. In contrast, at the cellular level cancer is caused by one or more genetic mutations that cause the cell to divide rapidly and disregard the normal intercellular signals to stop dividing. While there are sometimes significant abnormalities in protein production and function, these are a side effect of the cancer rather than the underlying cause.
my name is kery im so very my oh my its a little bit scary boys wanna Mary lookin at my dairy hey u can stare but if u touch ima very pretty as a picture sweeter then a swisher mad cause im cutier then da girl dat with ya
real' mad? probs go to hell
Reproduce like mad!
IDEK ! , & I'm mad !!
idiot mad
mommy gets mad
eat chicken ARE YOU MAD OR YOU DON'T HAVE A BRAIN
u have 2 be really mad at sum thing 2 become a super sayin for example goku was mad at freza for killing krillin and vegeta was mad at goku for being stronger than him and gohan was mad at cell for i dont know what
The vast majority of living things have a cell structure even if they are single celled. There are however a few exceptions. Viruses do not. Instead of a cell membrane they have a protein jacket. Pirons (responsible for mad cow disease and scarpies) are just exotic enzymes capable of reproducing themselves. It is debatable whether virus and Pirons are actually living things.
Your boss will get really mad.
Because you sound disorganized. Just give him your cell no.
