A forest has two groups of plants that appear to be very similar both phenotypically and genotypically. The major difference is
Gennadij [26K]
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.

Why do metals conduct electricity? Brainliest! <br> Already looked it up, so don't try it :)
Romashka-Z-Leto [24]

Answer:

Luckily I did the same thing and it was in my docs

Explanation:

Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.

Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.

Your grandma thinks that the theory of evolution can't be possible because she has never seen a monkey turn into a human. How co
Elena-2011 [213]
That evolution could not possibly happen in such a short period of time, but instead occurs over long amounts of time such as billions of years. Also, we did not come from monkeys we have common ancestors with them.
