A student studies the data for the population size of birds in an area over time. The student claims that the birds never exceeded their carrying capacity and displays this graph in support of the claim. Which statements below are true
about the student's claim? You may select more than one statement.
A)
The claim is neither supported nor refuted by the data.
B)
The claim is true because the birds experienced periods of exponential
growth.
The claim is false because the population decreases every time overshoot
occurs.
D
The claim is true because the birds are at a stable equilibrium with the
environment
E)
The claim is false because the population fluctuates above and below the
carrying capacity

Elephants in the savanna regions of africa dig holes in dried up river beds to reach water lying just below the surface. these holes provide drinking water for other animals as well. so, without the elephants, many animals might otherwise die from lack of water during the dry season. the location in which the elephants live is an example of a/n and the role they play in creating water holes is an example of a a) ecosystem; habitat b) community; niche c) habitat; niche d) niche; habitat

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
