Explanation:

what does 50 percent humidity mean? A. The air contains 50 percent of the moisture it can hold before precipitation occurs B. There is a 50 percent change of precipitation C. The air temperature is 50 degrees celsius D. There is a 50 percent chance of a thunderstorm occurring

Answers

Answer: The correct answer is-

A. The air contains 50 percent of the moisture it can hold before precipitation occurs.

Humidity can be described as the presence of gaseous state of water (that is water vapor) in the atmosphere or air.

It indicates the chances of occurance of precipitation or fog in the weather.

50% humidity represents the relative humidity, indicating that air is 50% saturated with moisture, which could be held by air before precipitation occurs .


50% humidity indicates that before precipitation the air withholds 50% moisture and it is known as relative humidity.

Further Explanation:

The amount of moisture the air contains is defined by humidity. A particular amount of water vapor is present in the air which depends on the temperature of the air. The warmer air contains holds more water within it. The relative humidity is defined as the content of water vapor found in the air in relation to the amount it can actually hold. When the relative humidity is low, it implies that the air can comparatively withhold more moisture at that particular temperature and this makes the air dry.

For example, it is estimated that a cubic meter of air is able to hold 18grams of water as a maximum value at 20 degrees C. Similarly, at 25 degrees C, 22 grams of water can be held by the air. Therefore, if 22 grams of water is contained in a cubic meter of air at 25 degrees C, then there is 100% relative humidity. But if the same amount of air holds 11 grams of water, the relative humidity is said to be 50%.

The relative humidity plays a major role in maintaining our level of comfort. A 100% relative humidity means that there will be no evaporation of water and the moisture has fully saturated the air. For cooling, the body requires to evaporate the moisture from the skin. A low relative humidity enables the body to release moisture and make the body cooler. At 100% relative humidity, the body feels much hotter as compared to the actual temperature. This is because the body does not sweat to evaporate due to high humidity.

A textile company has started a program to recycle textiles so they are not added to a nearby landfill as part of the waste stream. The company collects old T-shirts, sorts them by color, breaksdown the fibers, and respins the fibers into yarn which is used to make new shirts. The recycling process is different from traditional manufacturing because it does not use dyes and it reduces
the amount of water used in the manufacturing process to make new shirts
(a) One drawback of traditional textile manufacturing is that it can release dyes into nearby rivers
( Identify an ecosystem service provided by rivers.
(1) Assuming the dyes are dark in color, describe how photosynthetic algae living in the water would be affected by the release of dyes into rivers.
(18) Textile dyes often contain heavy metals such as lead, chromium, and cadmium Describe how heavy metals in nearby rivers could affect predators at the top of the food chain

Answers

Answer:

i. An ecosystem service provided by river include water for irrigation and drinking.

ii. Photosynthetic algae living in the water would be affected by the release of dyes into the rivers because dyes can block sunlight and prevent photosynthesis. Algae is the base of most river ecosystem so without direct sunlight due to the dye in the water, the entire ecosystem would be in jeopardy.

iii. Heavy metals in nearby rivers could affect predators at the top of the food chain because the metals consumed by primary and secondary consumers would be digested by the predators on top. The toxins from the heavy metal build up the higher in the food chain.

Why is it important for scientists to develop a way to grow tissues that have a built-in system to supply blood

Answers

  • It is important for the scientists to grow the tissues that have a built in system to supply blood to decreases the chances of organ rejection.
  • There is a very serious issue regarding this the transplanted organ does not gets the vascular blood supply which is the main reason for organ rejection.
  • If there will be tissues with its own blood supply then it will not be ejected by the body.
A lack of blood flow determines the number of cell layers that can
survive when they are transplanted
