wifes homework thread this will be ongoin thanks for the help

Hi, i'm Dom's wife Bridgette, he says you guys are really smart. So here is my first question. thanks again

The following experiment is used for the corresponding question.

A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in mid-summer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs.

How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below.



In each of the four environments, one of the caterpillars was fed oak flowers, the other oak leaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets).


In the figure above, which of the following is not a plausible hypothesis to explain the difference in caterpillar appearance observed in this population?
1 Differences in air pressure, due to differences in elevation, trigger the development of different types of caterpillars.
2 The longer day lengths of summer trigger the development of twig-like caterpillars.
3The cooler temperatures of spring trigger the development of flowerlike caterpillars.
4Differences in diet trigger the development of different types of cat

Ouch... you're making my head hurt. Let me grab a beer and I'll check back..

 

[ntw0rk]

Number 1...


There is nothing to indicate that pressure had anything to do with the development of the larvae

 

[SilvrSRT10]

I think I'd pick #1 also.

 

[WOLFRAM]

NUMBER "1"

 

[labontecsi]

Number 1...


There is nothing to indicate that pressure had anything to do with the development of the larvae

:dito: :withstupid:
I wanna play again.

 

[ntw0rk]

:dito: :withstupid:

HEY!!:argh: I Resemble that remark!!

 

[ViperJeff]

What was the question?

 

[Dom426]

Number 1...

thank you!!!

And another one

"Conservation of energy" refers to the fact that _____.
a the entropy of the universe is always increasing
b the net amount of disorder is always increasing
c if you conserve energy you will not be as tired
d energy cannot be created or destroyed but can be converted from one form to another
e no chemical reaction is 100 percent efficient

 

[Rockin Ronnie]

I would think number 1 also!!!

 

[OCBob]

And another one

"Conservation of energy" refers to the fact that _____.
a the entropy of the universe is always increasing
b the net amount of disorder is always increasing
c if you conserve energy you will not be as tired
d energy cannot be created or destroyed but can be converted from one form to another
e no chemical reaction is 100 percent efficient

The answer to that is D

 

[ChrisAZ]

I say D as well.

b the net amount of disorder is always increasing
c if you conserve energy you will not be as tired
d energy cannot be created or destroyed but can be converted from one form to another
e no chemical reaction is 100 percent efficient

It is D

In physics, the law of 'conservation of energy' states that the total amount of energy in an isolated system remains constant and cannot be created, although it may change forms, e.g. friction turns kinetic energy into heat (radiant energy). In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems, and is the more encompassing version of the conservation of energy. In short, the law of conservation of energy states that energy can neither be created nor destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same).

Good Luck!

 

[Venom Power]

Yes it has to be number one. Air pressure and elevation have absolutely nothing to do with which time of the year the eggs are laid or hatched. You would have to know the average air pressure of any given location the oak being used was in. And elevation of the oak isn't going to change multiple times a year.

Answers 2 and 3 suggest it makes more sense for a living organism to adapt to its environment.. As for answer 4, very simply, :dontknow: you are what you eat.


As for the second question, the answer IS D..


I want more questions.. Science is my thing..

 

[Wifey]

Hey, this is kinda fun - Like a group homework thing

Now, if I can post up my english questions and Bridgette keeps posting her science questions we can ALL help each other and Bridgette and Wifey will get A's :rock: :rock: :rock:

Good idea Bridgette and good luck with your homework :marchmellow: :marchmellow:

D is correct.

Bridgette, there is a technique for responding to multiple choice questions it has several steps:

1. You must have read the relevant material prior to responding to the multiple choice questions.
2. You must understand that most multiple choice questions are vocabulary tests that require you to discriminated small differences between defined terms.
3. In most well designed multiple choice questions all but two of the responses can usually be deleted because they are not relevant responses (if you have read the assigned material).
4. Close reading of the question and narrowing of the response choices to two possible responses will heighten your percentage of success.
5. If you really do not know which of the two possible alternatives is the correct response, research has found that 80% of the time, if you have studied the material assigned, your first inclination will be the correct answer. The mind is a wonderful thing, its long term memory is pretty accurate if left to its own devices. The hazard is that many over think their responses and fail to prepare and then fail to trust their brain. I can show you examples on ever exam I administer, of situations where people have put down the correct response and then gone back and over thought their response and changed a correct initial guess to a wrong answer. Trust your impulses if you have studied the material.

I completely agree with Roy




- HOWEVER, if you get in a bind, and none of them make sense, you can always use google There are many reference resources out there that are helpful to students

So do I, I think , but I wish we had a translator for them fancy phrases
