Many naturally occurring environmental exposures increase risk for cancer. Residents in many parts of North America are exposed

Katena32 [7]

Answer:

RADON GAS

Explanation:

Radon is a naturally occurring gas, which is produced due to the radioactive decay of the Radium element. It is one of the dense gas that is mostly concentrated in the lower portion of the houses, and are trapped in the cracks and fractures of the walls of houses and buildings.

Radon gas is an invisible, colorless and odorless gas, which is a very harmful gas, and exposure to Radon gas can cause an individual to suffer from cancer.

In recent studies, it has been found that in many parts of North America, a large number of residents are exposed to Radon gas, which led to an increased risk of cancer.

Locate Cullowhee, NC, Albuquerque, NM, and Los Angeles, CA on a map. Based on your data, which city would you expect to have the

kompoz [17]

Annual range is the difference of the mean temperature between the hottest and the coldest month.

Cullowhee, NC,
Hottest month:
July - Ave. High: 85 °F ; Ave. Low - 62 °F . Mean = (85+62)/2 = 73.5 °F
Coldest month:
January - Ave. High: 48 °F ; Ave. Low - 24 °F. Mean = (48+24)/2 = 36 °F
Annual Temperature range = 73.5 - 36 = 37.5 °F

Albuquerque, NM, - largest annual temperature range
Hottest Month:
July: Ave High: 90 °F ; Ave. Low: 66 °F; Mean = (90 + 66) / 2 = 78 °F
Coldest Month:
December: Ave High: 46 °F ; Ave. Low 26 °F ; Mean = (46 + 26)/2 = 36 °F
Annual Temperature range = 78 - 36 = 42 °F

Los Angeles, CA - lowest annual temperature range
Hottest Month:
August: Ave High: 79 °F ; Ave. Low: 62 °F ; Mean = (79 + 62) / 2 = 70.5 °F
Coldest Month:
December-March: Ave High: 67 °F ; Ave. Low: 51 °F ; Mean = (67 + 51) / 2= 59 °F
Annual Temperature range = 70.5 - 59 = 11.5 °F

The sense of smell is different from the other senses in that its sensory pathways are ____________________________.

9966 [12]

The olfactory system is involved in the sense of smell. The receptors of smell are not routed through the thalamus. The signals id directly routed from the olfactory bulb to the olfactory cortex and thalamus is not contacted in between. This is the difference between the taste and smell receptors, although both of their receptors are stimulated from mucus/saliva in the mouth.

How could activating a transcription factor cause long-term cellular changes?

valentinak56 [21]

The role of the effector(s) that result in a short-term cellular change in a changing the activation state of an enzyme going from inact to act this happens for instance when activating an enzyme to increase sugar metabolism while Long-term cellular changes are generally the result of changes in DNA transcription, i.e. a protein can be made to begin cellular replication by activating the cell cycle.
