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.

Can you explain why sc in capisco and capisci sound different, but c and ch in gioco and giochi sound similar, despite the spell
lidiya [134]

Answer:

The difference is due to the succeeding vowel sound strength (whether it is weak or strong)

Explanation:

"ch" produces "k" like sound. Whenever , alphabet "c" with in any word comes before any weak vowel sound such as i  or e , it always sound as "ch".

Therefore, c and ch in gioco and giochi are sound similar.

"sc" sounds like "sh" when it comes before any weak vowel sound (as in the case of capisci)

"sc" sounds like "sk" when it comes before any strong vowel sound (as in the case of capisco)
