trust me i’m right lol
He's actually a biologist who specializes in organic chemistry. But since that's not in the answer choices, i'd recommend putting Scientist or Dermatologist.
A basic experiment involves a minimum of two participant groups. The two participants are the experimental group and the control group. An experimental group receives the variable being tested, and one variable is tested at a time. The experimental group is compared to a control group, which does not receive the test variable.
Complete question:
In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.
1. In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is -------
2. If you examine 100 F₁ plants from the testcross and find that they all have purple flowers with tall stems, you should conclude that the genotype of your original pea plant is -------
3. If you examine 100 F₁ plants from the testcross and find that 44 have purple flowers with tall stems and 56 have purple flowers with short stems, you should conclude that the genotype of your original pea plant is -------
4. If you examine 100 F₁ plants from the testcross and find that 53 have purple flowers with tall stems and 47 have white flowers with tall stems, you should conclude that the genotype of your original pea plant is
-------
5. If you examine 100 F₁ plants from the testcross and find that 23 have purple flowers with tall stems, 26 have white flowers and tall stems, 24 have purple flowers with short stems, and 27 have white flowers with short stems, you should conclude that the genotype of your original pea plant is

<u>Note:</u> You will find the complete answer and explanation in the attached file "peaplants1" due to technical problems.
Answer:
Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using t<u>he distance it travels or its speed
.</u>
. If the force increases, car 2 will travel <u>slower or farther</u> The independent variable, or what’s being manipulated in the experiment, is <u>the starting height of car 1 or the type of bumper attached to car 2
</u>
he dependent variable, or what’s responding, is <u>the distance car 2 travels or the speed of car 1
</u>
The height and starting position on the ramp are constants in this experiment.

hope this help
i know that you figure out the answer
