Answer:
For any real experiment there must be at least five things: an independent variable, a dependent variable, control variables, and two groups often one experimental and one control.
Carlos hypothesis is that by fixing leaks their water consumption would be lower. As such his dependent variable is the water consumption and his independent variable (the one he is manipulating) is the amount of leaks in the house.
In order to make this an experiment Carlos needs to first make sure there is an actual decrease in the water consumed, and second he needs to make sure it's due to the fixed leaks. So to do this Carlos should measure their water consumption during a period of time before fixing the leaks and then measure the water use for the same period of time after fixing. The harder part is making sure that no other variables can interfere, these are called control variables. For example if before fixing the leaks Carlos had a huge party and had to wash a lot of dishes any decrease in water could be due to this. Therefore he would need to either make sure water is used for the same things in the same amounts during these two periods or track any increases due to specific events happening in only one of the periods.
Answer:
The correct answer is option c) Random assignment
Explanation:
The procedure that experimenters need to use to make sure that participants in both the treatment and control groups are not aware of the purpose of the experiment is known as the random assignment.
Random assignment means that each group, either a control group or experimental, has the equal opportunity to be assigned to any of the assignments being held. There is no discrimination or preference included.
Schools kind of tell you what to think it's better that they teach or to think how we want and not how are teachers want. in other words it's better to be a thinker than a follower.
Answer:
The correct answer to the question: If neither you nor your spouse has either albinism or cystic fibrosis, what are the odds that your first child will have both albinism and cystic fibrosis, would be: 1 in 16.
Explanation:
The topic of genetics, and especially ineritance of traits, whether from parents, or grandparents, or anyone directly linked to your line, is a pretty complex one and it depends entirely on two factors: chromosomal dominance and recessiveness, and the probability combinations that arise from crossing these. Essentially, in this case, both you and your partner have directly inherited the genes for both albinism and CF, but these have not been dominant in you, but recessive, for both conditions. The odds of a child of yours receiving and actually displaying the traits for both albinism and CF will depend entirely on the crossing of genetical material, dominant and recessive chromosomes from both you and your partner. Even though albinism and CF are recessive traits, they can become the feature that will be displayed on your child by combination and probability. This probability in this case gives 1/16.
