Which of the following best describes all the possible places carbon can go once it is in an acacia tree in the savanna?

**read carefully, there are correct answers and then there is the best answer**

question 5 options:

the carbon will either go back into the atmosphere by cellular respiration or into an herbivore when they eat the leaves of the acacia tree.

the carbon could go into a lion or be used to become part of the acacia tree (biosynthesis)

the carbon would move to the soil where the decomposers would put it back into the atmosphere.

the carbon could go into the atmosphere through cellular respiration, it could become part of the acacia tree (biosynthesis), it could die and move to the soil, or an herbivore could eat the leaves of the acacia tree

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
