During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher

first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.

Answer:

e

Explanation:

<em>The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.</em>

It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. <u>If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.</u>

The correct option is e.

Blizzard [7]
<span>In their book "Interaction between temperament and environment" behavior geneticists Robert Plomin and Denise Daniels state, "Two children in the same family are [apart from their shared genes] as different from one another as are pairs of children selected randomly from the population." There may be many reasons children in the same family are so different from one another but their finding boils down to the environment. To a large extent the environment influences personality, psychopathology, and cognitive abilities. Environmental differences between children in the same family represent the major source of character and environmental variance.</span>

Which three steps describe how an animal obtains and uses energy for growth?
harina [27]

Answer:

Option C. First, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.

Explanation:

When one animal eats another animal, the body of organisms is made of higher molecules such as carbohydrate, protein and lipids. These large molecules are broken down into simpler substances in the stomach such as glucose, amino acid and faty acid. These substances are absorbed by the body and release energy from them.
