Answer:
c. have changed the behavior of elk.
Explanation:
Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.
The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.
Answer:
Average for zero: 51.1
Average for two: 76.3
Average for four: 87.4
Average for six: 103.3
Blank 1: 51.1
Blank 2: 76.3
Blank 3: 87.4
Blank 4: 103.3
Explanation:
The above answers gave the average of each of the set of numbers.
To calculate the average of a set of numbers, It is done by simply summing the numbers and then dividing the numbers by the total number of values in that set of numbers.
From the data given, zero, two, four and six all have their set of numbers. So, with those values, the average was calculated.
An amphibian can live both on land and in water. ... Instead of drinking water, frogs soak the moisture into their body through their skin. Frogs breathe through their nostrils while also absorbing about half the air they need through their skin.
Hope this helps :) - sorry if I am wrong - if I am right can I get brainliest please??
Student 2 is right.
<h3>Constant variables</h3>
In research investigations, some variables should be kept constant across various experimental groups in order for the outcome of the investigation to be valid.
For example, in order to test how flatworms respond to different environments, one variable that should be kept constant is the flatworms. The flatworms to be used must be of the same species, sex, age, etc.
The investigator can then go ahead to divide the flatworms into two or more groups and then subject them to different environments. Other variables should also be kept constant in order to determine the effects that are only specific to the different environments only.
