The map below shows the State and Local Air Monitoring Stations (SLAMS). Each red dot represents one of nearly 4,000 air quality monitoring stations in the SLAMS network. Data from these stations is compiled so that levels of air pollutants can be assessed by the Environmental Protection Agency.

Suppose that recent data from the SLAMS network showed a general rise in air pollution levels. What would such data most likely suggest?
A.
That stricter air quality controls are necessary to reduce emissions.
B.
That air quality controls are no longer needed to reduce emissions.
C.
That the SLAMS network as a whole is not functioning properly.
D.
That air quality controls need to be relaxed to reduce emissions.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
