Question

1. the first step in a scientific investigation is to ask a ______________.
2. in a punnett square, the probability of an offspring inheriting a specific trait is shown as a ______________.
3. the physical appearance of an organism is referred to as its ______________.
4. a ______________ is a possible answer to a scientific question that can be tested.
5. when you repeat an experiment several times, you are doing ______________.
6. the ______________ is the number found by adding all data values together and dividing by how many there are.
7. the likelihood that an event will occur is called ______________
8. in genetics, a ______________ cross involves the study of one trait at a time
9. if a coin is flipped, the probability of it landing on heads is ______________.

Explanation:

1. In scientific investigation, the first step is to ask a question to define the problem.
2. Punnett squares use ratios to show inheritance probabilities.
3. Phenotype refers to an organism's physical appearance.
4. A hypothesis is a testable answer to a scientific question.
5. Repeating an experiment is replication, which validates results.
6. The mean (average) is calculated by summing data and dividing by the count.
7. Probability measures the likelihood of an event.
8. A monohybrid cross studies one trait in genetics.
9. A coin has two sides, so the probability of heads is \( \frac{1}{2} \).

Answer:

1. question
2. ratio
3. phenotype
4. hypothesis
5. replication
6. mean (average)
7. probability
8. monohybrid
9. \( \frac{1}{2} \)
