Answer:
<em>The impact of a drug on cancer. </em>
IV: drug DV: reduced/increased/neutral cancer growth.
<em>Plants grow more when exposed to trap music. </em>
IV: trap music DV: plant growth indicators (height, biomass, etc.)
<em>Exercise improves health. </em>
IV: Exercise regime DV: health indicators
<em>Does the amount of vitamin A in their diet affect the weight of rats? </em>
IV: amount of vitamin A DV: weight of rats.
Explanation:
First, it is imperative to understand what dependent and independent variables are.
<em>Dependent variables are the main variables researchers set out to determine during the course of an experiment.</em> Their values are dependent on some other variables that are inputted by the researchers.
<em>Independent variables are variables that are directly inputted by researchers. </em>Their values can be manipulated or varied to see the kind of effects they will have on dependent variables.
Hence;
- To determine the impact of a drug on cancer, the<u> input/independent variable would be the drug itself</u> while the <u>dependent variable would be the kind of effects they produce on cancer - reduced, increased or, neutral growth.</u>
- Plants grow more when exposed to trap music: the<u> input/independent variable would be trap music</u> while the <u>dependent variable would be heigh, biomass, or any other indicator of growth in plants</u>.
- Exercise improves health: <u>the input/independent variable would be exercise regimes</u> while the i<u>ndependent variable would be indicators of health. </u>
- Does the amount of vitamin A in their diet affect the weight of rats?: <u>the input/independent variable here would be the amount of vitamin A </u>while the <u>dependent variable would the weight of rats.</u>
Answer:
Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:
- Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.
- Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.
Hence, bat boxes at houses have a positive effect on the environment.
