An infection is the invasion and multiplication of pathogenic microbes in an individual or population. Pathogenicity is defined by the capacity of a microbe to cause damage in a (susceptible) host. Virulence is defined as the relative capacity of a microbe to cause damage in a host. brainliest???

How can we make kaleidoscope?How does it work?
No links!!
No spams!!
Answer/Explanation:
colorful semi-transparent stuff, foil, a tube, and clear tape.
put the foil inside but not on a roll, make it into a shape like triangle or hexagon. Put a layer of clear tape on one end of the tube and then cover it with the semi-transparent stuff and sandwich it in with more tape. put tape on the other end and limit the amount you see to a small hole.
You will see down the tube to the colorful stuff but the foil will (hopefully) reflect the colors to make the weird look of a Kaleidoscope.
The light coming through the colorful stuff is bouncing off the foil at a right angle from side to side until it hits the pinhole and goes into the eye where the cone cells in our eye and we see the colorful tube of fun.

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
Answer:
Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body.

If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
Answer:
Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.
Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.
