Ateam of ecologists are studying four different ecosystems with varying levels of biodiversity. the ecologists categorize the different levels of biodiversity for the four ecosystems as shown in the table below.

genetic diversity species diversity habitat diversity
ecosystem a low low medium
ecosystem b medium high medium
ecosystem c high low low
ecosystem d medium low high
based on the information above, which ecosystem would most likely recover the fastest from a natural disruption?

ecosystem a

a

ecosystem b

b

ecosystem c

c

ecosystem d

If 1.63 times 10 negative 4 of helium dissolves in 100.0g of water, what is the concentration in parts per million

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
