Answer:

An independent variable is one which can be changed or manipulated in an experiment. The effect of the independent variable is observed on the dependent variable. The dependent variable is the one which does not change or manipulated in an experiment by the investigator. The changes that occur in the dependent variable with respect to the independent variable is the outcome of the experimentation process.

In the given situation, the medicine and the placebo drug are the independent samples whereas the effect of the medicine and placebo drug can be observed on the time they require to cure the headache is the dependent variable.

The answer is seasonal changes.

<span>Animals that live in taiga biomes had to adapt to seasonal changes, by changing their fur or feather color. For example, snowshoe rabbit and arctic fox live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way they evade predators because it is more difficult for their predators to spot them.</span>

Make a list of the potential benefits and harms that might arise from knowing your complete genome sequence.
MaRussiya [10]

Answer:

The benefits and harms of learning about my DNA are mostly in medical, personal, civil and criminal fields.

Explanation:

a) Pros: learning about my genome sequence could provide new information on the genetic basis of poorly understood diseases with the potential to provide new therapies, immediate benefits based on the current understanding of genetic and health. Being aware of elevated risks for known diseases could allow me to make proactive decisions about my health such as visiting the doctor frequently for more check ups, screening. Choosing one type of prescription drug over another based on my metabolism, changing my diet or exercise plan, informing reproductive decisions, moreover, I would personalize my health care precisely.

b) Cons: the potential harms are the privacy invation, database exposure , which could lead to serious implications for the criminal justice system, which generally seeks to increase the availability of DNA samples from the population. It would create genetic discrimination, meaning that would be harder to find jobs, contract insurance,  even though we have a Genetic Information Nondiscrimination Act.
