Answer:
Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) ...

Risk factors for infectious diseases:
- Having a weak or compromised immune system
- Taking medications such as steroids or immuno-suppressants
- Having HIV or AIDS
- Not being vaccinated against an infectious disease
- Having cancer or a disorder that weakens the immune system
- Being malnourished
Explanation:
Apart from exposure to germs, certain other factors increase the risk of contracting an infectious disease.
Compromised or Suppressed Immune system:
- A compromised or suppressed immune system means that your immune system cannot effectively fight against pathogens.
- The immune system can either be weak naturally, due to malnourishment, undernourishment or be compromised by certain disorders or medication.
- Immunosuppressants are drugs that suppress or inactivate the immune system. These are prescribed to patients with auto-immune disorders (a disorder in which the body's own immune system starts attacking the body's own cells and organs).
HIV/AIDS
- Since HIV attacks an important component, the T-helper cells of the immune system, HIV positive or AIDS individuals have a weak immune system that lowers their ability to fight diseases.
Not Vaccinated:
Vaccination increases a body's capability to fight deadly infections. Un-vaccinated individuals are at a higher risk of contacting diseases.

If the distance is doubled the force of gravity is one fourth as strong as before.
