Albert, a student researcher, varies the amount of food given to rats in an experiment to measure the effect on their learning behavior. In albert's study, the amount of food given is the independent variable.
An independent variable is under the control of the experimenter. Independent variable does not depend on the other variables involved in the experiment. Since the amount of food is varied, it is not depending on other variables like size of mice, weight, etc.
Answer:
The correct answer is : a clear orderly arrangement and ability to reproduce.
Explanation:
Properties of life include different aspects and key characteristic of an organism or life such as, cells or order, adaption, reproduction, homeostasis, growth and development, regulation, sensitivity to a stimuli and other.
In green turtles and virus both shows reproducing ability and clear orderly arrangement as properties of life. They both can produce their offspring and increase their numbers.
Thus, the correct answer is : a clear orderly arrangement and ability to reproduce.
<u>Answer:</u>
Q: Which skeletal system <u>disorder</u> might she be suffering from?
A: <u>Osteoporosis</u>
Q: What <u>techniques</u> could be used to diagnose her condition?
A: <u>Bone mineral density (BMD) test</u> or <u>dual energy X-ray absorptiometry (DXA) scan</u>
Q: What treatments are available?
A: Medication, healthy food.
<u>Explanation:</u>
<u>The vertebral discs between vertebrae could shrink with age</u>. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to <u>osteoporosis</u>.
A <u>bone mineral density test</u>, also known as <u>dual energy X-ray absorptiometry</u> scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses <u>X-rays</u> to measure the content of calcium and thus strength of bones.
A person who is already suffering from osteoporosis should be treated with <u>medicine</u> right away so that it <u>stops</u> further <u>deterioration of the bones</u> and <u>avoid any future bone fractures</u>. Further, it can be handled by <u>eating a healthy diet</u> and <u>supplements</u> such as <u>vitamins D</u>. In case some of the bones/vertebrae are <u>already fractured</u>, <u>surgical approaches</u> might be necessary.

Answer:
One method of estimating the time of death is to measure body temperature. The normal equation for this is: 37.5oC - 1.5 oC This formula equates to the body temperature (37.5oC), which loses 1.5 oC per hour until the temperature of the body is that of the environment around it; known as the ambient temperature.
