Answer:
The cell membrane is a semi-permeable membrane that surrounds the cytoplasm . the main fuction is to protect the interior of the cell by allowing certain substances get into the cell while keeping other substances out.
Explanation:
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.

Attached below is a sample food web which provides a general solution to your question
<h3>What is a food web ?</h3>
A food web is connection of food chains containing different organisms in the ecosystem. A food web shows the flow of energy from one trophic level to another. As we move up the trophic level 10% of the energy from the previous levels is transferred to the next trophic level in the food web
Hence we can conclude that although the organisms related to your question is missing a sample food web is provided below

Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
So..the answer should be D. Eukaryotic cells have a true membrane-bound nucleus and prokaryotes do not
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
So..it can't be C. or A. or even B.
Correct me if I'm wrong.
