2 and 3 are too similar to distinguish because they both are saying it's been back up on several different accounts but 3 seems like a more solid answer go with 3
It’s the endoplasmic reticulum . Have a great day !
Answer:
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.
Sickle cells is a group of disorders that cause red blood cells to become misshapen and break down.
Despite the fact that their numerous abnormalities would ordinarily make them great targets for apoptosis, cancer cells even avoid programmed cell death. As cancer progresses, cells cross the borders of healthy tissue and metastasis (spread) to other locations throughout the body.
Cancer cells:
- First and foremost, cancer is a complex illness, meaning that several faulty genes are implicated. It is not the case that one faulty gene causes a cell to develop into a malignant cell.
- Metastasis refers to the spread of a cancer.
- Uncontrolled growth is a given if there is a constitutively active RTK growth factor. However, the cell has additional defense systems to prevent such unchecked proliferation. If nothing is done, the cell will undergo apoptosis and perish. The development of cancer would not exist.
Some of the typical characteristics of cancer cells include -
- Because they are anchorage independent, cancer cells can grow in both semi-solid and suspension mediums.
- Its proliferation is unaffected by contact with neighboring cells, or contact inhibition.
- Layers of cancerous cells are formed.
- Cancerous cells have a variety of shapes.
- Telomerase is expressed by tumor cells.
- They do not go through apoptosis, have damaged cell cycle regulatory genes, and proliferate uncontrollably.
- For them to grow, angiogenesis is necessary.
