Answer:
They are different because ethanol is a compound that is made by a certain amount of carbon, oxygen and hydrogen, these are the elements that made up ethanol.
Explanation:
Think of it like this ethanol is a cake and carbon, oxygen and hydrogen is the eggs, flours and sugar that is used to make the cake.
The following option are correct:
1. There will be interspecific competition between foxes and tigers.
Competition for food between animals of different species is called interspecific competition while that between the same animal species is called intraspecific competition.
2. The energy received at the tropic level of carnivores will be less than the usual amount.
The energy received at the trophic level become reduced because the amount of food available for the carnivores has been reduced.
3. There will be decreased biomass at the trophic level of carnivores.
Decrease biomass will occur at the trophic level of carnivores because, those carnivores that can not survive the food reduction problem will die off.
Answer:
The mean weight of the progeny is 
grams
Explanation:
Given -
Mean fruit weight of tomato plant (M1) 
g
Narrow sense heritability (h2) 
g
Mean weight of tomato plant selected for artificial selection (M0) 
g
Substituting the given values in above equation, we get -
The mean weight of the progeny is grams
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group.
Count the number of offspring each plant produces.
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals.
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate.
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group.
I'd also put a hypothesis in there somewhere too.
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
Divide the amount in half for every 2 minutes
0 minutes = 20 grams
2 minutes = 20/2 = 10
4 minutes = 10/2 = 5
6 minutes = 5/2 = 2.5
8 minutes = 2.5/2 = 1.25 grams
