whats your name well?????
Answer:
The three parts of the cell theory are as follows
(1) All living things are made up of cells
(2) Cells are the smallest units (or most basic building blocks) of life
(3) All cells come from preexisting cells through the process of cell division.
Explanation:
(1) The first characteristic of a living thing is that they are made up of cells. A cell is the basic building block of all organisms. It is the smallest unit of organization in a living thing. They contain the organism's hereditary information (DNA) and can make copies of themselves in a process called mitosis.
(2) Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.
(3) All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells. Energy flow (metabolism and biochemistry) occurs within cells.

Explanation:Matching the following brain structures with its description gives
1.Arachnoid mater – Middle meninx
2. Subarachnoid space - located between the arachnoid mater and the pia mater.
3. Cerebral aqueduct - connects third ventricle and fourth ventricle.
4.Arachnoid villus -structure that projects through the dura mater into arachnoid mater
5. Pia mater - Meninx that follows every convolution of the brain.
6. First and second ventricles – Lateral Ventricles
7. Fourth ventricle - ventricle located between brainstem and cerebellum.
8. Apertures - passageway for cerebrospinal fluid between fourth ventricles and subarachnoid space
9.Third ventricle - ventricle associated with diencephalon.
10. Dura mater – Outermost meninx
11. Interventricular foramina - Connects the lateral ventricle and third ventricle
12. Superior sagittal sinus - Collects venous blood and cerebrospinal fluid.
Answer:
I believe it is E. All of the above
Explanation:
The answer would be a. cancer cells become invasive and grow into a body tissue. Apoptosis is a programmed cell death that certain cells undergo in order to protect the organism. However, sometimes these cells can avoid apoptosis and do not respond to signals to stop dividing (known as uncontrolled cell division); this results in a mass of extra cells (tumor) and that's how cancer happens. Hope this made sense :)
