Answer:
the first and sencond options (1 and 2)
Explanation:
Answer: C
Explanation: The atomic mass is 22.990 so it would be C
The single type of bacteria is not adequate to make any conclusions.
D. DD = 0.0225; Dd = 0.1275; dd = 0.7225
The value of Dd is different in question.
<u>Explanation:</u>
Given -
Dark colored = DD, Dd
light colored = dd
Frequency of allele D = 0.15
Frequency of allele d = 0.85
Hardy-Weinberg equilibrium is applied.
DD = 0.15 X 0.15 = 0.0225
Dd = 0.15 X 0.85 = 0.1275
dd = 0.85 X 0.85 = 0.7225
Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
