Trey wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 1. Carbon enters the atmosphere as carbon dioxide from respiration and the burning of fossil fuels.
Step 2. Plants absorb carbon dioxide in the air and use it to make their own food using photosynthesis.
Step 3. Plant-eating animals consume the carbon stored in plants.

If step 2 is removed, which statement best describes the effects of this missing step on the carbon cycle?

(A) Less carbon is stored in the ground for long-term storage.
(B) There is a decrease in the amount of carbon stored in the air.
(C) More carbon is stored in plants instead of the air.
(D) Animals consume foods without stored carbon.

Mr. j, age 42, is a construction worker in las vegas. he recently noticed that a mole on his face seemed to be getting larger and darker. at first he did not worry because he was in the sun a lot and assumed the change may have been caused by sunburn. after a month, not only was the mole larger and darker, but it appeared to be “bumpy.” his doctor diagnosed a malignant melanoma skin cancer following biopsy of the nevus. mr. j reports pain in his right shin that does not go away when he puts his feet up or sleeps. discussion questions 1. relate mr. j’s skin changes to the warning signs for malignant melanoma.
