Answer:
The correct answers are option a. The greater the undifferentiated cell count, the more aggressive the cancer and b. Malignant tumors have the potential to kill the host.
Explanation:
Anaplasia is a medical term used to describe a condition of cells with poor cellular differentiation. It is known that the great the anaplasia, the more aggresive is the cancer. The tumors that have this characteristic are known as anaplastic carcinoma. This malignant tumors have the potential to kill the host when they metastasize to other organs.
Homeostasis can be defined as the state of maintenance of the constant internal conditions by the living organisms. The homeostasis is maintained by the body so that it may function properly. The homeostasis will be disturbed by the reduced intake of the food and water. Healthy intake of water and food is essential in maintaining the homeostasis of the body. The elevated or depressed blood pH along with extreme body temperatures will also disturb the homeostasis of the body making the person sick. Moreover, certain infectious organisms also alters the homeostasis of the body.
Hence, all the options are correct.
<em>A </em><em>virus </em><em>is an agent that causes infections and diseases.

<h2>Further Explanation
</h2>
Viruses are microscopic parasites that infect cells of biological organisms. Viruses are obligate parasites, this is because viruses can only reproduce in living material by invading and utilizing the cells of living things because viruses do not have cellular equipment to reproduce themselves.
The term virus usually refers to particles that infect eukaryote cells (multicellular organisms and many types of single-cell organisms), while the term bacteriophage or phage is used for types that attack types of prokaryotic cells (bacteria and other organisms that do not cell nucleated).
The virus has been infecting since the days before Christ, this is evidenced by the existence of several discoveries, namely reports of virus infections in hieroglyphics in Memphis, the capital of ancient Egypt (1400 BC) which shows the existence of poliomyelitis. In addition, King Pharaoh Ramses V died in 1196 BC and is believed to have died of the smallpox virus.
In 1880, Louis Pasteur and Robert Koch put forward a "germ theory" namely that microorganisms are the cause of disease. At that time also the famous Koch Postulate which is very well known today, namely:
- A disease agent must be present in every case of the disease
- The agent must be isolated from the host and can be grown in vitro
- When the muri agent culture is inoculated into susceptible healthy host cells, it can cause disease
- The same agent can be taken and re-isolated from the infected host
<h3>Various kinds of viral infections
</h3>
- Acute infections are infections that last for a short time but can also be fatal.
- Chronic infection is a prolonged viral infection so there is a risk of symptoms of the disease coming back.

The electrons in these bonds carry energy. Within the power plants of the cell (mitochondria), energy is used to add one molecule of inorganic phosphate (P) to a molecule of adenosine diphosphate (ADP). The amount of energy stored is about 7,300 calories for every mole of ATP formed.
