Answer: An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

Explanation: Example: What is a good outcome variable for deciding whether cancer treatment in a country has been improving?

A first thought might be "number of deaths in the country from cancer in one year." But number of deaths might increase simply because the population is increasing. Or it might go down if cancer incidence is decreasing. "Percent of the population that dies of cancer in one year" would take care of the first problem, but not the second.

This example makes the point that a rate is often a better measure than a count.

If this is just based off the independent variable it would be the outcome of the manipulation what happens to your dependent variable you give one plant fertilizer the other one none which plant grows better is the outcome variable

Hello. It is not possible to access the website you are referring to, but I will try to help you in the best possible way.

Natural selection is the term created by Chales Darwin to compose a theory of biological evolution. According to this term, living beings that have characteristics favorable to their survival, in relation to the environment in which they live, are more likely to survive and pass these characteristics on to their descendants, while those that do not have these characteristics are more likely to die. .

An example of this can be seen in a population of lizards that live in environments with a lot of grass. According to natural selection, green colored lizards would have better advantages of surviving because they would be camouflaged in the grass and would not be seen by predators, unlike red lizards, which would be easily identified and captured by predators. therefore, the population of red lizards would decrease until it ceased to exist, while the population and green lizards would survive and generate other green lizards.

Which of the light micrographs shows epithelial tissue that forms thyroid gland and secretes hormones?

ruslelena [56]

The Simple cuboidal epithelium forms thyroid gland and secretes hormones is shown in the picture attached.

Its main functions are secretion and absorption. It has an abundance of organelles to facilitate active transport frequently found in glands, such as salivary glands, the thyroid gland, and the pancreas, where its function is secretion.

The epithelial cells tend to be cubical in form after they are inactive, however additional columnar after they are actively secreting hormones.
The epithelial cells accumulate iodine from the blood and use this component within the synthesis of thyroglobulin, an oversized compound protein that forms the mixture.
