1. Testing only one variable
A controlled variable means its the one that stays the same. In a controlled experiment, it means there is only one manipulated, (changed) variable.
Respiration is an action of breathing. Breathing is you do to live. Breathing is a process of taking air into the lungs and exhaling it out of the lungs.
Answer: one offspring out of the four will have a recessive-recessive genotype.
Explanation: A cross between two parents who are heterozygous for a gene that has a simple dominant-recessive pattern of inheritance will produce four offsprings: one will be homozygous dominant, two will be heterozygous dominant while one will be homozygous recessive.
Homozygous dominant offspring has two dominant alleles, heterozygous dominant offspring has one dominant allele and one recessive allele while a homozygous recessive offspring has two recessive alleles.
For example, a cross between two parents that are heterozygous (Tt) for tall will produce one TT, two Tt and one tt. TT is homozygous dominant, Tt is heterozygous dominant and tt is homozygous recessive. An offspring with genotype tt has a two recessive alleles thus have a recessive-recessive genotype. Therefore the number of offsprings with recessive-recessive genotype is one.

Answer:
It protects your eyes from particles, such as dust, and sweat.
Explanation:
Answer:
1. The chi-square statistic is 0. The p-value is 1. Not significant at p < .05.
The chi-square statistic with Yates correction is 0.0642. The p-value is .800028. Not significant at p < .05.
Explanation:
2. By generating large sets of data the ratio will remain same (F1 = 3:1, F2 = 9:3:3:1) according to the Chi-Square analysis. In actual reality, it fails to justify by giving a probability value of 1 that is impossible due to the exceptions of Co-Dominance and Incomplete Dominance...
