Answer:
d. cross-sectional study
Explanation:
In research, a cross-sectional study consists of a gathering of data from a population or a subset of the population we want to investigate at an specific point of time. In other words, the data will give us an idea of what's happening within a group in a particular moment in time.
In this example, the researcher gives 20-year-olds, 40-year-olds, and 60-year-olds a questionnaire. He wants to know if older people are calmer than younger ones. We can see that <u>he wants to know what's happening within this groups (the 20 year-olds, the 40's and the 60's) during this particular time of their life </u>and therefore determine if the 60 year-olds are calmer. Therefore this is an example of cross-sectional study.
This conversion of one form of energy into another is called: <u>transduction</u>.
<u>Explanation</u>:
In the above scenario, the light energy received by Samantha on opening her eyes to see the flowers was then converted into neural messages to process by the brain. This kind of conversion of energy is known as transduction.
Transduction is done as the physical energy cannot be directly transmitted to the brain. It is then converted into electrical signals like neural impulses and transmitted to the brain. The transmission of signals from an exterior of cell to its interior is known as cell signaling or signal transduction. To achieve appropriate response, the signals received by cells should be effectively transmitted to another cell.
