kobusy [5.1K]

Answer:

No. They will need to repeat their experiment several times, since the weather and times were different both days.

Explanation:

When a scientific experiment is conducted, one independent variable shall be changed in each experiment at a time so that the results of the experiment are authentic and we can easily determine which independent variable caused a change in the dependent variable.

If more than one independent variable is changed in the same experiment, then it will be difficult to interpret that which variable caused the change.

<u><em>Similarly, Maria and her brother need to repeat their experiment several times with just changing one variable at a time. </em></u>

agasfer [191]

Answer:

Hawk

Explanation:

Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.

telo118 [61]
The population of the mice would most likely increase. This is because the number of predators of mice will decrease. Predators are those that feed on others, in this case mice. When predators decrease, the prey (which would be the mice) will be able to populate thus leading to an increase in population.
