Answer:
The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem's ability to remain stable when confronted with a disturbance.

balloon to various depths and observed the result. Which one of the following best
describes what happed to the balloon as it went deeper?
(a) The balloon got larger because the pressure of the water around it increased
compared with the pressure inside the balloon.
(b) The balloon got larger because the pressure of the water around it decreased
compared with the pressure inside the balloon.
(c) The balloon got smaller because the pressure of the water around it increased
compared with the pressure inside the balloon.
(d) The balloon got smaller because the pressure of the water around it decreased
compared with the pressure inside the balloon.
The balloon got smaller because the pressure of the water around it increased compared with the pressure inside the balloon. Therefore, the correct answer is (C).
As the student submerged the balloon to various depths, the pressure of the water around the balloon increased, which caused the balloon to get smaller. This is because the pressure inside the balloon remained constant, while the pressure outside increased.
The helium inside the balloon would have been compressed by the increased pressure of the water, causing the balloon to decrease in size. This phenomenon can be explained by Boyle's law, which states that the volume of a gas is inversely proportional to the pressure of its surroundings.

Answer:
Convection
Explanation:
Difference in temperature induces convection currents. The mantle material close to Earth's core is quite hot in comparison to the one close to the lithosphere, which is cooler. Earth's convection currents are very slow in movement. They flow at rates of a few centimeters per year. It is believed by scientists that the movement of mantle material carries the plates of the lithosphere with it which causes the plates to move.
Answer:
The answer is Convection
Explanation:
Plate movement happens because of a process of heat transfer called convection. Convection is the movement produced when a gas, liquid, or plastic is unevenly heated.
False
B. a perfect pesticide.
C. subject to biological magnification.
D. deadly to herbivores.
Answer:
C. subject to biological magnification.
Explanation:
DDT is an insecticide that exhibits slow metabolism and excretion. The slow breakdown of DDT causes it to accumulate in fat tissues of organisms. Biological magnification refers to the process of increased concentration of toxic chemicals in the tissues of living beings of higher tropic levels. The accumulated higher concentration of DDT poses harmful effects on the health of top consumers.
