Answer:
variables that help to increased the rate of diffusion are
1) concentration of glucose
2) by increasing the number of membrane carriers
Explanation:
variables that help to increased the rate of diffusion are
1) concentration of glucose - the rate of diffusion increased when molecules concentration outside the cell is more than internal concentration. It is all part of the concentration gradient. Higher the concentration gradient higher will be the rate of diffusion
2) by increasing the number of membrane carriers - the rate of diffusion increased by increasing concentration of solute in the cell which is increase by carrier proteins.
Answer: The correct answer is Solomon four-group design.
Explanation: The Solomon four-group design is a research design in which the four groups of the research have different experiences,
1- The first group is Pretested,
2- The second group or control group is pretested as well,
3- The third group receives treatment and then is post-tested.
4- The fourth group receives no treatment, is post-tested.
This design is done to acknowledge the influence of pretesting in posttest results.
In conclusion, the research design is experimental and its called Solomon four-group design.
Answer and Explanation:
What Robert Putnam meant to say by the statement was that the number of active meaningful societies, and the extent to which they are socially active, would go a long way in determining the health and well-being of the citizens: the number and level of activity of Italy’s choral societies (choir groups) have had a great impact on the wellbeing of many Italians—similar to getting health bills reimbursed, or using high-level social activities to enhance well-being.
