Answer:

Earth's atmosphere filters out harmful radiation from the sun.

Explanation:

The sun is earth's star and sunlight helps light up and warm the earth and also helps in the process of photosynthesis. Sunlight on the other hand, produces harmful rays called Ultraviolet radiation or UV rays.

These ultraviolet radiation is dangerous to our skin and ultimately our body as a whole. Fortunately for us, the earth's atmosphere has a protective layer called the Ozone layer. The Ozone layer serves to filter out and block the harmful ultraviolet radiation and prevent it from reaching the earth, thereby protecting us.

Sadly though, the Ozone layer is getting depleted by human activities which emit harmful gases like carbon dioxide into the atmosphere. Activities such as oil drilling, automobile emissions, destruction of forests etc. These activities affect the Ozone layer leading to it's gradual disappearance and letting in the harmful UV rays. A phenomenon referred to as global warming.

A researcher recorded that a chemical reaction required 2.90 gal water and raised the temperature of the reaction vessel by 57 F
Bess [88]

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>

<u>Explanation:</u>

Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.

We have to convert the researcher's volume into the SL units of liter.

<em>So, we know that 1 gallon = 3.875 liters</em>.

Then we have to convert 2.90 gallons of water in to liters.

Then  , volume in L =(volume\ in \ gal) \times  (3.875 L/1 gal)                                   = (2.90) \times (3.875L/1 gal)                                  

= 11.0L

<em>Then the required volume in L= 11.0L</em>

Are the counts of blue crabs in Maryland accurate for 1991 and 1999?
kirill [66]
The population of blue crabs will be difficult for the scientists to count because of unreliable ways and natural phenomenon or occurrence that causes the water's temperature to rise. According to climate reports, year 1999 have warmer temperature and this probably caused the blue crabs to be active, but on year 1990 female blue crabs sustained a normal quantity of production of their species. Thus, the estimated count of population of blue crabs is probably more accurate in year 1990 than year 1999 because of the stable production of the female crabs.
