Answer:
Recessive traits can only be expressed with recessive alleles.
Explanation:
According to the law of dominance as proposed by Gregor Mendel, an allele of a gene is capable of masking the phenotypic expression of another allele in the same gene. This allele that masks or that is expressed is called DOMINANT allele while the allele being masked is the RECESSIVE allele.
The dominant allele is responsible for the dominant trait in the organism. Hence, the dominant trait will be expressed when the dominant allele and recessive allele combines (heterozygous). However, the recessive trait is only expressible when the recessive alleles are the same in the gene.

Answer:
Independent variable: MASS OF OBJECT
Explanation:
In an experiment, the INDEPENDENT VARIABLE is the variable that is subject to change or manipulation by the experimenter. Hence, this question is asking for the independent variable when it says which variable must Hillary change during the experiment.
According to the question, Hillary is trying to investigate how an object’s mass affects the average speed at which it travels when dropped until it hits the ground. This means that the variable she must change/independent variable is the MASS OF OBJECT dropped.
