Which best describes the relationship between population size, carrying capacity, and limiting factors?
myrzilka [38]

Answer: The correct answer is- C.

Carrying capacity can be described as the maximum number of organisms belonging to a particular species that can be sustained by resources present in the area.

Due to the presence of limiting factors ( such as food, water, weather conditions), the size of a population usually stays near its carrying capacity.

This is because initially population experience rapid growth but later on due the limiting factor ( environmental factor that causes decline in the population) it will decline and then stabilize near the carrying capacity.

Thus, population size stays near the carrying capacity because of limiting factors.

How do viruses start
Tems11 [23]

Answer:

They essentially first start with a small organism. This organism is then transferred to a host, usually transferred from eating/touching something. Then, the host gets infected with said virus.

The host will then pass on the organism by sneezing, coughing, and/or touching them. This continues on, usually until a cure is found. It can still have the ability to transfer, generally from people who don't get the cure.

Viruses can sometimes have a larger impact during different times.

Some people may also be more subject to the virus if they have vitamin deficiency or other health problems/issues.

At 95% humidity, what percentage of the air around us is water vapour? Can you drown? ...?
NISA [10]
Humidity<span> is the amount of </span>water<span> vapor in the air. </span>Humidity<span> varies from place to place and season to season.

</span><span>There are two types of Humidity:
Absolute Humidity and Relative Humidity.
 
Absolute Humidity is the weight of water vapor in a cubic meter of air. The higher the temperature, the higher the ability of air to hold water. For example, at 20 C, the maximum Absolute Humidity is 17.3 g/m^3. At 50 C, the maximum Absolute Humidity is 83.0 g/m^3.  Relative Humidity is the % of water vapor in the air relative to the maximum possible Absolute Humidity.</span><span>

</span><span>When we use the word Humidity in ordinary speech, we're talking about Relative Humidity. So,  if the humidity is 95% or even 100%, that doesn't mean 95% or 100% of the air around us is water vapor; just the amount of water in the air is 95% or 100% of the maximum it can hold. 
</span>
Therefore, we wouldn't drown at 95% humidity, we will be uncomfortable due to the heat content of air and water but we are still be able to breathe. I hope this answer helps.
