Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
<h3><u>Answer;</u></h3>
mechanoreception
In the context of sensation and perception, the detection of pressure by sensory receptors is called <u>mechanoreception</u>.
<h3><u>Explanation</u>;</h3>
- Mechanoreception involves detection and response towards certain kinds of stimuli such as touch, sound, and changes in pressure or posture.
