Answer:
The Fertile Crescent is bounded on the west by the Mediterranean Sea and on the East by the Persian Gulf. The Tigris and Euphrates rivers flow through the heart of the Fertile Crescent.
The answer is: Space
Space will include all abiotic components that exist within a certain geographical location (this include things such as water, air, foods, land, caves, etc) .
Even though space indeed provide all organisms need to survive, All of these components in the space wouldn't necessarily guarantee the organisms' survival itself. Those organisms still need to compete with one another in order to acquire those resources.
Answer:
Ceiling effect
Explanation:
Full question
Hannah wants to see if her new technique of ping-pong playing can increase one's ping-pong performance. She asks the U.S. Olympic ping-pong team to work with her. Half of the U.S Olympic team is randomly assigned to be taught by the new style, the experimental group, and the other randomly assigned half are not, the control group. Her technique does not significantly increase the performance of the experimental group compared to the control group, perhaps because they are already so good at the sport. This could be an example of
a. the need for matching groups.
b. a ceiling effect.
c. the need for determining initial comparability.
d. an internally invalid study.* .
Ceiling effect
In Hannah case the experimental group and the control group was pretty much not significantly different because both groups were already good at the sport. Her experiment couldnt function properly because there is no accuracy to the test since both groups perform well, this is known as a ceiling effect
The term ceiling effect is a measurement limitation that occurs when the highest possible score or close to the highest score on a test or measurement instrument is reached, thereby decreasing the likelihood that the testing instrument has accurately measured the intended group.
