Brainiest!   during an algal bloom in a local lake, the population of algae increases at a rapid rate and covers the surface of the water. algae have a short lifespan and die very quickly. microbes (bacteria) begin the decomposition process of these dead aquatic plants. this causes a significant drop in the amount of dissolved oxygen in the water and leads to a “dead zone” where aquatic plants and animals cannot survive. which of the following best describes what happens as a result? a. without oxygen produced from cellular respiration, the plants and animals cannot perform photosynthesis and therefore aren’t able to make enough atp energy to power their vital metabolic processes needed for survival. b. without oxygen produced from photosynthesis, the plants and animals cannot perform cellular respiration and therefore aren’t able to make enough atp energy to power the vital metabolic processes needed for survival. c. plants do not require any oxygen, so they are not harmed in an algae bloom. only the animal population will be affected by the drop in dissolved oxygen levels. 

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.
