Scientists are not completely sure, but it is positives that these cells would have to produce their own energy rather than obtaining it by consuming other cells. Also these cells were simple and most likely hollow spherical blogs of plasma membrane with some type of genetic material inside (DNA, RNA, proteins, etc.)
What else can I help you with?
The cell membrane controls what goes in and out of the cell true or false?
True. The cell membrane is selectively permeable, meaning it regulates the movement of substances in and out of the cell to maintain internal balance and protect against harmful substances.
Is it true that in a cell fractionation the first step is to place the cells into a centrifuge?
Yes, in cell fractionation, the first step is typically to homogenize the cells to break them open and release their contents. The homogenate is then usually subjected to centrifugation to separate the different cellular components based on their size, density, and other properties.
True or false the nucleus is the control center for the cell?
True. The nucleus is considered the control center of the cell because it houses the cell's genetic material (DNA) and directs the cell's activities by regulating gene expression and protein synthesis.
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
True. The cell wall is selectively permeable, allowing only certain molecules to pass through, which helps maintain homeostasis by regulating what enters and exits the cell. Additionally, the cell wall provides structural support and protection for the cell.
When the inside of a cell is negatively charged while the outside of the cell is positively charged it is known as resting potential true or false?
True. This difference in charge, with the inside of the cell more negatively charged compared to the outside, is known as the resting membrane potential. This is a key characteristic of the resting state of a neuron.
Is the main function of the cell membrane is to control what comes into and out of the cell true or false?
True.
In order to center a title that exists in cell A1 which is very small you need to merge several horizontal cells together first true or false?
true
Is the main function of the cell membrane is to control what comes into comes into and out of a cell true or false?
It is true
A wet cell is an electrochemical cell in which the electrolyte is a?
true
True or False Multiple changes in DNA are required to change an abnormal cell into a cancer cell?
True.
Can the condition of a cell only be true using excel 2007?
No. The condition of a cell can be either true or false.
Is the following sentence true or false the main function of the cell membrane is to control comes into and out of a cell?
TRUE
The process of cell differentiation is not well understood but involves the turning off or on of genetic information in the cell?
True!!
To replace the contents of a cell you must first select the cell and then key in the new data. True or false?
True. It is not even necessary to delete the existing contents first, which some people do. Just select the cell and type in the new data and the old data will be replaced. If you want to retain some of the old data, click on the formula bar or press the F2 to edit the contents.
A condition of a cell can on only be true is that true or false?
The answeris true pg. # ex118
Does the zygote results from the union of the sperm and egg cell?
The zygote is the first cellular form of development in mammals. This results from the union of the sperm and egg cell.
What is the first argument required by the built-in IF function?
For my example you have a number '2' in cell D4 The first argument would be: Logical Test. Example of IF Argument: =IF(Logical Test, True, False) So the logical test is what you are testing, IF Cell D4=2, the value would be true, if it didn't equal 2 the value would be false.
