Body size affects energy expended for physical activity is TRUE.
<h3><u>Explanation:</u></h3>
Expenditure of energy is found by the body size and body composition of the being while doing any physical activity. Higher weight has a higher energy requirement. It needs higher maintenance and higher resting requirement also.
Smaller and leaner objects move with more active energy as the physical activity required in doing so is less. Since they have less body weight and require less maintenance their energy requirement is less. Hence energy expended is also less in such cases.
In any physical activity, there cannot be a comparison between smaller and heavier beings' amount of expending energy since it depends on the speed, effort, work out efficiency and time taken by them. But, body size certainly affects energy expended during any physical activity.
Answer:
Rob never thought to use his rolling pin because of e. functional fixedness.
Explanation:
Functional fixedness is a type of cognitive bias. Functional fixedness means a person is unable to see another use for an object other than its traditional use. This inability prevents a person from finding creative solutions and alternatives when dealing with issues. Rob could very well have used his rolling pin and saved himself some time and money by not leaving home to buy a cooking mallet. However, due to functional fixedness, he could not see another use for the rolling pin besides the one that is traditional.
He is more interested in the Internal Validity. Internal validity is of significate importance in scientific studies, and indicate if the variable analyzed is the cause of the effect obtained in the research, or whether the effect obtained is the product of another variable. For example, in an investigation analyzing the effect of anxiety on test results, care should be taken not to study other effects that may affect test results, such as fatigue or lack of study.
Answer:
The first blank is good, the second one is standard deviations.
Explanation:
Random samples provide good estimates of population averages if the samples have small standard deviations.
Doesn't it make sense now? I hope this helps you! :)
