In McMillen and Austin’s research (1971), participants who had lied were more likely to volunteer a large amount of time.
Explanation:
The research work conducted by Mcmillen and Austin in the year 1971, included college students as participants of the research. In this process they are asked to perform a small test of intelligence. One portion of them was asked to cheat and lie and the rest were left not to cheat.
After finishing the test, the participants were asked to help the administrator to conduct the next round of test for other slot of participants. It was seen that the students who did not lie or cheat, helped them in their work for about 2 minutes. But students, who did lie, stayed and helped for 53 minutes.
The reason is they are afraid of being picked on by a bigger crowd therefore increasing their chances to be bullied
Answer:
The correct option is: e. molecules move across the plasma membrane against their concentration gradient
Explanation:
Active transport refers to the <u>movement of the particles or molecules from higher concentration to lower concentration, across the plasma membrane of a cell.</u> This transport requires cellular energy as the movement of the molecules is <u>against the concentration gradient</u>.
Active transport can be divided into primary and secondary active transport.
Ans. (B). '
Since iron is required to make hemoglobin and myoglobin, iron deficiency decreases the amount of oxygen in the blood and in the muscles.'
Anemia represents deficiency of blood cells to deliver sufficient oxygen throughout the body organs. Myoglobin and hemoglobin are oxygen-transporting proteins, present in muscles and red blood cells, respectively.
Both these proteins are made up of polypeptide chains and heme groups. The heme group contains iron, hence, iron-deficiency causes insufficient amount of myoglobin and hemoglobin. Due to this, the amount of oxygen decreases in muscles and blood and leads to anemia.
Thus, the correct answer is option (B).
