The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
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.

<em>Photosynthesis processes used plants and other autotrophs to capture light energy and use it to power chemical reactions and convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches. </em>
<em>The </em><em>similarities</em><em> and </em><em>differences</em><em> between photosynthesis and cellular respiration:</em>
<em>The Similarities; </em>
- <em>Both involve in production of energy
</em>
- <em>
Both involve the exchange of gases</em>
<em>The Differences: </em>
- <em>Photosynthesis takes put in chloroplast, where as cellular respiration takes put in mitochondria.</em>
- <em>Photosynthesis happen as it were during presence of daylight where as cellular respiration happens all the time.</em>
