The answer is C
The more plants there are, the more consumers there are. If there aren't enough plants, the consumers have no way of getting energy, and therefore cannot survive. The species also matters, because certain species of plants can only be eaten by certain species of consumers.
Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.
Answer:
50%
Explanation:
Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.
One homozygous dominant parent = XX
One heterozygous parent = Xx
X X
X XX XX
x Xx Xx
So two out of our four outcomes are heterozygous for the trait. That means the answer is <u>B. 50%.</u>
