I say it would be B. because it is the safest for you. You should never reach across a flame because of the risk of catching on fire. And never leave a flame unattended. Heating a liquid in a closed container could be dangerous as well because it heats fast and could go wrong. I hope this helps!

A major disturbance that the ecosystem was able to recover completely from. ____________________________________________________
attashe74 [19]

Complete Question:

I made the grass diseased. This caused all of the populations above it (rabbit, snake, and hawk) to rapidly decrease over the 12 month period

(a) A major disturbance that the ecosystem was able to recover completely from __________

(b) A major disturbance that caused the ecosystem to stabilize at a new equilibrium ____________

(c) A major disturbance that caused the ecosystem to completely collapse __________

ANSWER:

(a) reducing the hawks to nearly zero

(b) removing all of the hawks

(c) removing all the diseased.

Explanation:

(a) reducing the hawks to nearly zero will cause low depletion of the producer (plants) and this will allow the plant to grow (without visible depletion) over a period of time.

(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there's no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.

(c) for ecosystem to collapse, it's important to note that the removal of the producer (plants) will be bring about the loss of the ecosystem. Since, their is no manufacturer of food, the primary consumer (rabbit) in the food chain will be starved and overtime the rabbits will be wiped out and this will caused the loss of secondary and tertiary consumer in the long run.

19. If a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified?
Illusion [34]

<u>ANSWER:</u>

The correct option is B- Qualitative.

<u>EXPLANATION:</u>

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.

Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
