the data cable below gives estimates for two populations in a candra ecosystem. polar bears are predators,
and arctic seals are their main prey.

recall from lesson 21 that only a small part of the energy in 2017 organism is passed to the organism that feeds on it. as a result, a prey population is almost always much larger than the predator population. one way to graph a predator/prey relationship is co label the left vertical axis with a scale for one population and the right vertical axis with a scale for the other.
use the data cable above to construct a line graph of the seal and bear populations over 10 years. make your graph on a separate piece of graph paper. label your axes, and include a key to distinguisha the
populations shown
question: what is the approximate size range for each population?

One gene can influence trait(s). one trait can be determined by gene(s).

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.

Why do we perceive objects as retaining their brightness under different lighting levels?
