because the nucleus is surrounded by a nuclear envelope - a double membrane.
since it has 2 membranes it is twice as thick as a single plasma membrane
Nothing. Whole blood is always given away. What private companies WILL pay for is plasma, and it's something like $65 per week--you can sell plasma twice a week.
The animal cell has only 3 main types of cell 'ingredients' (cytoplast, cell surface membrane and the nucleus), whereas the plant cell has twice that many (chloroplast, cell wall, vacuole, cytoplasm, nucleus and the cell surface membrane).
Walled up means to be enclosed within walls. If I surround you with 4 walls standing at 90 degrees (straight up and down) made of very thick glass and twice your height, it is very unlikely you would escape - you are walled up.
You twice it.
You take that medication twice a day
Of course not. It just means that it has two membranes.
The plasma membrane is the most thoroughly studied of all cell membranes, and it is largely through investigations of the plasma membrane that our current concepts of membrane structure have evolved. Theplasma membranes of mammalian red blood cells (erythrocytes) have been particularly useful as a model for studies of membrane structure. Mammalian red blood cells do not contain nuclei or internal membranes, so they represent a source from which pure plasma membranes can be easily isolated for biochemical analysis. Indeed, studies of the red blood cell plasma membrane provided the first evidence that biological membranes consist of lipid bilayers. In 1925, two Dutch scientists (E. Gorter and R. Grendel) extracted the membrane lipidsfrom a known number of red blood cells, corresponding to a known surface area of plasma membrane. They then determined the surface area occupied by a monolayer of the extracted lipid spread out at an air-water interface. The surface area of the lipid monolayer turned out to be twice that occupied by the erythrocyteplasma membranes, leading to the conclusion that the membranes consisted of lipid bilayers rather than monolayers
Even if the material is the same, the thick lens is stronger because strength increases when thickness increases. If you pull on the lens in its plane and it is twice as thick then it is twice as strong. If you push on the lens perpendicular to it and it is twice as thick then it is eight times stronger. This is strength of materials theory taken in college for engineering.
Yes, twice.
This depends on your definition of Commonly Nuclear weapons have been used twice in the history of the world. The other view is that they have been used twice to often.
To be more accurate the nucleus doesn't split in mitosis because after DNA replicates in interphase and prophase starts nuclear membrane is removed and there is no longer a nucleus just free chromosomes. These separate in anaphase and then in telophase where two daughter cells are going to be produced the nuclear membrane reforms as well as the nucleolus forming two cells with identical nuclei.
cant repeat the same process twice!,
30um is twice as thick as 15um. um stands for *10^-6
Nuclear weapons have been used in war twice- both times in 1945, when the US bombed the Japanese cities of Hiroshima and Nagasaki.
Canadian mesh is twice as thick as hard mesh.
AnswerI don't believe a reputable plasma donation center would even allow you to donate twice a week. No, it's not good for you to do so. You need your blood before anyone else.^I don't know where you got your information from. Plasma centers such as Advanced Bio-Systems offer incentives for donors who donate eight times in the same month. It's plasma, not blood. Your body easily replaces it if you are keeping hydrated properly.
Fried potatoes or chips. in Ireland they are still called chips, and they are about twice as thick.
