The first one seems the most correct
1) Mice not radio waved.
2) Radio
3) Strength of mice
4) Maybe inconclusive.
5) Improves strength
Explanation:
- Control Group - Mice not radio waved.
- Independent Variable - radio.
- Dependent Variable - Strength of mice.
- What should Bart's conclusion be? Maybe inconclusive.
- How could Bart's experiment be improved? Improves strength
Experimental setup
setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.
Control Setup
setup that is identical to the experimental setup, only it does not contain a variable.
Independent Variable
The one factor that is change by the person doing the experiment
Dependent Variable
The factor which is measured in the experiment
Constant
all the factor that stay the same in an experiment.
Answer:
C. The drum will work on Earth and in outer space. The drum will not work under the water.
This startle reflex (aka moro reflex) is/was present in us as newborns.
It's triggered when there's an unexpected reaction. Example: Loud noise, sudden movement.
The baby will tighten his/her body, fling out arms, sort of like giving him/herself a hug. It happens because the baby is trying to protect itself from harm.
It normally leaves thanks to the mother's care, normally 6 weeks after the newborn is born.
If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).
To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.
