You are working with a team of scientists who are investigating the biochemical control system involved in how animals digest fats in their meals. You have evidence that there must be a signal molecule involved that is released soon after the fats are consumed. When this signal molecule is present it triggers activation of appropriate digestive enzymes and cellular uptake transporters until the meal has been fully digested. Based on this information, what type of signal molecule would you predict is involved in this process

When an ecosystem ecologist looks at landscape full of interacting plants and animals, all kinds of questions about how ecosystems function come to mind, and they are not that easy to answer. For example, in an African savanna, the following observations can be made: Gazelles, zebras, and wildebeest eat grass, but wildebeest eat a lot of grass; giraffes eat the leaves of acacia trees; lions and cheetahs eat zebras, gazelles, and wildebeest; more lightning-caused fires burn when there is more grass; more acacia trees grow when there are fewer fires. Predict how this savanna ecosystem might change if the cheetah and lion populations decline due to a feline (cat) virus.
