The statement that a nucleus is the control center for the cell is a correct statement.True, the nucleus is the control center for the cell.
A primitive nucleus is a simple type of nucleus found in some organisms, such as prokaryotes, that lacks a membrane boundary separating it from the rest of the cell. In contrast, a true nucleus is a well-defined structure enclosed by a nuclear membrane found in eukaryotic cells, containing the genetic material and serving as the control center for the cell's activities.
hoe do you not get it?? the answer is obvious its true the other person has no prove and are trying to get u to fail ur science test trust me its true and u can search it up IM TRYING TO HELP U TRUST MEEE ;)
No - quite the opposite. The nucleus is where almost all of the DNA in a cell is found. Small amounts are also found in some organelles, such as mitochondria - and this is the only form of DNA found outside the nucleus.
True. The brain is the central organ of the nervous system and is responsible for regulating and coordinating the body's functions. It is the main control center for processing information and sending signals to the rest of the body.
Yes, it is possible for a Eukaryotic cell to have no nucleus. An example of a cell without a nucleus is the mammalian red blood cell. However, Eukaryotic cells without a nucleus, like red blood cells, are unable to replicate. This is why red blood cells need to be continuously produced in the bone marrow.
False, it is in the center of the cell
False. An alpha particle is equivalent to a helium-4 nucleus.
True.
true!
True. The brain is the control center of the body in humans, responsible for coordinating and regulating all bodily functions through the central nervous system.
False. A proton is found inside the nucleus of an atom.
Electrons surround the nucleus and are not inside one.
Not exactly. The cell has a large number of mitochondria and other units operating independent of the nucleus. They do their jobs based on feedback mechanisms. The most important part of the nucleus is DNA. The DNA provides templates for building proteins, but these templates are combined outside of the nucleus and no one knows how. So the more we know, the less we understand.
true
false.
---> Unitary!
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
