Answer:
Null hypothesis: the behavior of mosquito larvae doesn't change in the presence/absence of predators added to the tanks in Treatments 2 and 3.
Explanation:
In statistics, the null hypothesis states that there are no differences between the two variables tested in the experiment, while the alternative hypothesis uses the experimental data in order to reject the null hypothesis. In this case, the alternative hypothesis will use the data from treatments 2 and 3 to confirm that predators can modify the behavior of mosquito larvae.
Answer:
I think the answer is C
''Reusing plastic bags''
Explanation:
Removing carnivores from a forest has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.
If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.
Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.
This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.
so I think choice C is the answer

Explanation:
Answer:
shape
Explanation:
gases and liquids have very spread out particles and contain no particular shape. instead, they take the shape of whatever contains them. on the other side, a solid has a particular shape as the molecules are close together.
