The Answer is going to be C tall and short
Answer:
The experiment consists of three different treatments:
1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth
2- Fifty (50) no treated chili pepper plants that grown in normal conditions
3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)
<u>Dependent variable:</u> plant growth
<u>Independent variable:</u> the amount of substance x (suspected to slow down plant growth)
Explanation:
The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.
The piece of cheese in the refrigerator had the least amount of chemical change.
- Moulding occurs on substances which are warm and moist
- Mold thrives in warm and humid places
- In refrigerators, the environment is cool and dry
- This environment hinders the growth of mold
- The bacteria and fungi require optimum temperatures to flourish, which is not present in a refrigerator
- The cheese placed outside and on the counter will grow mold as those environments do not arrest the growth of mold
- Refrigeration ensures that food is not spoilt
Therefore, the least amount of chemical change takes place on the cheese placed in the refrigerator.

Answer;
The important role of experience in wiring the brain
Explanation;
-Brain development involves creating, strengthening, and discarding connections among the neurons; these connections are called synapses.
-These synapses organize the brain by forming pathways that connect the parts of the brain governing what we do.
-At birth the synapses present are those governing our bodily functions such as heart rate, breathing, eating, and sleeping.
