A decaying leaf on the forest floor has a C:N mass ratio of 50:1. A decomposer fungus with a biomass C:N ratio of 12:1 is breaking down the leaf and using it for growth with an efficiency of 40% (the fungus respires 6 g of C for every 10 g it decomposes and takes up). How much additional nitrogen does the fungus need to translocate from soil for each gram of biomass C growth

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.

Suppose you use three different scale to weigh a bag of oranges. one scale says the nag weighs 2.1 lb, and third says it weighs 2.1 lb. the actual weight of the bag of oranges is 2.153 lb. which of the following best decribes these results?

Bio molecules are essential to all living things. which biomolecule is “d” from the table
