Cancer is the uncontrolled growth of abnormal cells in the body. In the body, there are trillions of cells with various functions. These cells grow and divide to help the body function properly. Cells die when they become old or damaged, and new cells replace them.
Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and cells grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.
Observing a specific or general object, or subject.
The answer is hypernatremia. Common early symptoms attributed to this condition include a strong feeling of thirst, weakness, nausea, and loss of appetite. Normal serum sodium levels should range between 135 – 145 mmol/L. Hyperaldosteronism (increased production of aldosterone) may be the underlying cause of the condition.
Answer:
The correct answer is (b) 1%
Explanation:
Represented in an ecological energy pyramid, the seals would be in the third position from the bottom as <em>secondary consumers</em>.
In this example, the <em>base of the pyramid </em>will be represented by the coconut palms, the primary producers, also known as autotrophs, which create their food by <em>taking their energy from non-living sources</em> of energy, like the sun.
The second level consists of primary consumers. Herbivores feed solely on <em>primary producers</em>, in this case, the coconut crabs.
The third level would be the secondary consumers, usually carnivores and omnivores, in this case, the seals.
In this example, as seals would be the secondary consumers located at the third level of the pyramid from the bottom, they will receive about 1% of energy.

Answer:
See below
Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection
