The correct answer is C. Controlled experiments
Explanation:
A scientific claim is a statement that describes or explains a phenomenon of the world. These statements can be proven as valid or invalid only through scientific experiments, which involve testing in controlled conditions the phenomenon. This is the only way because the scientific method should be followed. For example, if the claim is that humidity affects the growth rate of cacti. The researcher will need to use multiple cacti and use different percentages of humidity to prove if humidity increases or decreases the growth rate. Also, in this case, other factors such as nutrients in the soil, exposition to sunlight, etc. should be controlled to guarantee these factors are equal for all plants. According to this, the one that serves as evidence for the scientific claim is controlled experiments.
Answer:
Friction decreased when he went from pavement to ice and then increased two more times.
Explanation:
joints form our musculoskeletal system which lets muscles move
parental genotype of fruit fly Long wing: short wing would be 1 : 1
In monohybrid cross the number of short wing will be equal to number of long wing
- Alternate forms of the same gene are called allele
- the two alleles for a particular gene are identical the gene pair is homozygous
- If an individual is homozygous for a particular trait then each parent contributed the same allele for that trait.
- If an individual is heterozygous for a particular trait then each parent contributed a different allele for that trait.
- The probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is 3/4.
