In a grassland ecosystem, plants require about 10,500 J of energy to maintain their bodies and power the biochemical reactions needed for survival. In this ecosystem after one very rainy winter, you calculate that the plants added about 20,500 J of new biomass. What was the gross primary production (in J) in this ecosystem? Group of answer choices

What are simmilarities and differences between anaerobic respiration in animal and yeast cells? would prefer to get simmilarities as i already got some differences. you!

Acell goes through cellular respiration and produces atp which it then uses to move a molecule across the cell membrane. how does the energy in the original glucose molecule change during this process? (2 points)

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
