Water has a higher specific heat capacity than land. Therefore it takes longer for the sun to warm up a body of water such as a lake or ocean than it does.
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.
Answer:
D) The myosin binding sites on actin are covered by tropomyosin
Explanation:
The muscle contraction and relaxation involves the myofilaments which physically contract and relax.
However, the physical contraction and relaxation are controlled by the other protein molecules called tropomyosin and troponin molecules.
The muscle contracts when a cross-bridge is formed between the myosin and actin but myosin binds actin only when myosin-binding site on actin is free of tropomyosin which usually covers in a relaxed state.
In the given question, when the drug is not ab;e to bind to the myosin-binding site therefore to shows that the myosin binding site is covered by the tropomyosin.
Thus, Option-D is the correct answer.
Answer:
9444.44 origins
Explanation:
From the given information:
The genome of D. melanogaster = 1.7 × 10⁸
1 sec = 30 base pair
1 min = 1800bp i.e. (30 × 60 = 1800)
5 Min = 9000 bp i.e. (1800 × 5 = 9000)
Suppose there was a single bidirectional origin, then the process would proceed as:
= 1.7 × 10⁸ / 2*(1 / sec / 30 bp)
= 2833333.333
SInce it only takes 300 seconds in ( 5 minutes), then:
There should be 2833333.333/300 = 9444.44 origins to accomplish suh feat.
