Depending on what you decide to create an experiment on that will vary but I can provide you some different terms to help you!
Experimental Group vs Control Group:
The Experimental Group is the group you test things on and the Control Group is the group that stays the same to help you compare data. For instance let's say you are a dentist testing a new toothpaste to see if it whitens teeth more. You have 25 people in the control group who are all using the old toothpaste. In the experimental control group you have 25 people all using the new toothpaste.
And Independent Variables vs Dependent Variables:
An Independent Variable is the variable you change in order to see how it affects the dependent variable. The Dependent Variable is what the independent variable affects. Following the toothpaste example the different types of toothpaste would be the Independent Variable because there are two and they are different. The Dependent Variable would be the number of people from each control group that have whiter teeth.
It would be this way because the amount of people that have whiter teeth is dependent on the toothpaste and how well it works
Option D because Earth is closer to the sun than Mars
The lymphatic system destroy harmful substances 'By producing antibodies'.
The lymphocytes contained in lymphatic organs are produced with other defence cells by the bone marrow. They are then dispersed to eliminate pathogens.
Answer: genotypic ratio 2/4
Phenotypic ratio 4/4 is the same
Explanation: suppose RR is the dominant female and Rr is the heterozygous male. Then after the cross genetically 2 have RR and 2 have Rr ratio. But phenotypically all 4 are the same.
Answer:
B
Explanation:
Offspring would all have genes of TT, TT, Tt and Tt. All offspring have the dominant tall gene.
