Option D would be that answer
Answer:
The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).
Explanation:
The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.
In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.
The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.
Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.

Answer:
The animal cell includes: a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes
Explanation:
These are all the structures of a basic animal cell, depending on which grade you are they get more complex. If so, then you can just ask me!
Hope this helps! :)
Answer:
nucleic acids and phospholipids
Explanation:
- Phosphorous is required to make two essential molecules in the body- the nuclei acid and the phospholipids.
- The nucleic acid contains carbon, hydrogen, oxygen, nitrogen, and phosphorus and is organic compounds that codes for the genetic information in an organism. There are two types of nucleic acid- ribonucleic acids and deoxyribonucleic acids, i.e RNA and DNA respectively. Both of them sugar-phosphate backbone and therefore, phosphorous is essential for the synthesis of nucleic acids in the body.
- Phospholipids make up the cell membrane and thus, phosphorous is also essential for their synthesis.
