Cells
movement of substances using energy against the concentration gradient (low → high)
What is active transport?
heterotroph who regulate the health of the ecosystem
what is a keystone species?
ATP
What is the end goal of cellular respiration?
pH of 9
What is a weak base (alkaline)?
Independent variable
What is the investigative/testing variable?
Not all particles can pass the cell membrane
environmental conditions that select for certain characteristics of individuals and select against other characteristics
What is a selective pressure?
Pyruvate and NADH
What are the products of glycolysis?
OH- ions determine this
What is a base/alkaline pH solution?
dependent variable
What is the variable that is being measured in an experiment?
Cells take in O2 and glucose, and release CO2 waste and water
How do cells maintain homeostasis?
An increase in predators leads to a decrease in prey.
What is a negative feedback loop?
the most ATP is made here
What is the electron transport chain?
pH 8.1
What is a normal ocean pH?
You set up an experiment to measure the amount of rainfall during each month of the year.
What is the independent variable?
Inside the cell: 15% solute concentration; outside the cell: 60%. The cell shrinks due to water moving out of the cell.
What is a hypertonic solution?
kelp--> urchin-->otters -->orcas
Urchins increased, overgrazing the kelp to near extinction, resulting in a destruction of the ecosystem.
What is the result of a decrease of otters (keystone species)?
CO2 and 2 ATP are produced here
What is the Citric Acid Cycle (Krebs)?
an increase of H+ ions found in the ocean, bringing its pH at 7.6
What is a ocean acidification?
You set up an experiment to measure the amount of rainfall during each month of the year.
What is the dependent variable?
This particle will travel, starting from the cells, capillaries, alveoli, lungs, nose/mouth, then the atmosphere.
What is the pathway of CO2 diffusion?
In an area of large, medium, and small otters, small and large otters have survival advantage.
What is disruptive selection?
Process done by both aerobic and anaerobic processes.
What is glycolysis?
role of photosynthesis in the carbon cycle
How is CO2 is removed from the atmosphere?
"If it rains in June, then the rainfall amount will be larger."
What is a hypothesis?
