Experiment: Three flies are placed in a cage with a fresh banana and a rotten apple. Researchers record where?
Which of the following is correct? Limit response to one answers. Testing 3 flies is adequate, as larger sample sizes are expensive to obtain and test. A sample size of three is not enough to be convincing--the three individuals could be unusual. Testing three different flies is a good idea, as it will give more confidence in the results.
Biology multiple choice! Help with experimental design for fruit flies. 10 points best answer?
So there is an experiment that tests whether fruit flies prefer a certain kind of fruit. Three flies are placed in a cage with a fresh banana and a rotten apple. Researchers record where they spend their time. 1. Which is correct? a. a sample size of 3 is not convincing - the flies could be unusual b. testing 3 flies is adequate. larger sample sizes are expensive c. testing 3 different flies is a good idea, it will give confident results 2. Which of the following is correct? a. its a good idea to test the flies at the same time b. the 3 flies shouldnt be tested at the same time- they could influence each others behavior
What examples do you know of evolution acting in catharsis to extinction events?
No, rather some geneticists have shown in recent years that genomes are devolving not evolving due to accumulation of mutations eventually leading to sufficient corruption and loss of genetic information to cause extinctions. This has been called increasing Genetic Entropy and is what is to be expected under the 2nd law of thermodynamics. There are some mechanisms built in to genomes by design to counteract the effect of mutations but eventually the accumulation is inevitable. Mutations by definition corrupt and lose information . Some say we have seen beneficial mutations but these are under very limited environmental conditions and still represent a loss of information and renders the organism still generally less fit to flourish. The type of complex information and structural pathways required for creation by evolution of new novel characteristics by mutations and natural selection has never been observed in nature and is purely blind speculation and a world view and interpretation of what limited observable evidence we have. This world view is naturalistic and designed as an alternative explanation of origins to exclude a creator of supreme intelligence.
What is wrong with the Indian education system?
9th standard:PTA meetingPhysics Teacher: Your son is very smart. He is hardworking too. Dad: Thanks sir! He studies well. He is passionate about physics.Physics Teacher: Yes. He has what it takes to be an IAS Officer. Prepare him for Civil Services. He would be a great officer.Dad: That's good to hear sir. I am just a 9th standard guy. All I knew was that I loved applying physics to daily life activities. I knew I loved Maths too. But I did not know about my future. I did not know what I would be or what I wanted to be. I approached my teacher the next day.Class - the next day:Me: Sir. I like physics. What is its future.Physics Teacher: The future of physics is full of possibilities. There is infinite scope for exploring the field.Me: Then why did you want me to be an IAS Officer.Physics Teacher: Its a very stable job. You get security. You can get others to do your work for you. You will have many servants. You can earn very much. Even though the salary from government is less, you get lots of gifts (not so subtle). If you pursue physics, you can't earn much. Home:Mom: How did the meeting go. Dad: Great! His teacher told me that he has what it takes to even crack Civil Services.Mom: He's too young. Let us give him a few years before we push him towards his goals. (My mother is a professor. I am lucky. Not all are lucky to be afforded this freedom.)Conclusion:I tell my teacher I like his subject. He tells me it has good future. But money is the ultimate objective and it has less scope to earn money. He tells me to pursue another field. I feel there is something fundamentally wrong if we educate our younger generation that one field has more priority over another. All are equal. It just depends on one's passion towards a field and a drive to pursue it.As someone said: "Where would they be if Lata Mangeshkar picked up a cricket bat and Sachin Tendulkar became a singer."
