With Simpson's Biodiversity Index, answers for Exam Q's I have done often exceed 1. What does this mean in terms of biodiversity?

that shouldn;t really happen Tom. So the two possibilities I'd look at are some kind of error in the calculation, or in some cases, rounding up might cause enough of a difference, to take a final answer that should have been 1 or just below 1, to something that is slightly greater than one.

good video, Thank you can i ask what domain do prokaryotes belong to?
@LSCBiology
9 жыл бұрын
It was found that there are two types of prokaryotes: the archaebacteria and the bacteria. This therefore resulted in the formation of two domains. The other four kingdoms were grouped together into the Eukaryotic domain. Altogether three domains.

Shazia Nawaz in the old classification system all the organisms without a nucleus were thought of as one kingdom, the prokaryotes. But based on new biochemical evidence, looking at the enzymes (such as RNA polymerase) and lipids of these prokaryotes, it became clear that there were in fact two very different groups. So the prokaryotes were divided into two domains, the archaea and the bacteria. The other four kingdoms (fungi, animals, plants, protoctists) all the one thing in common, that they were all eukaryotic, so Eukaryota became the third domain.

@DrBhasvar I will do what ever you want me to do ( very serious ) if you help me in this question : When investigating the effect of light intensity on the abundance of a specific species We are supposed to try and control all the factors (other than light) that could affect the percentage abundance So ,temperature, pH of soil, mineral content of soil, water content of soil and topography. My question is how do we control these factors ? In my unit 6 alternative to practical paper, there is 2 marks available for how to control these variables but they don’t say how to control them they just say “description of how this variable can be controlled” Please help I asked everybody I know (well, only those who take A level bio ) nobody knows

Easy. You don’t. In the field, you can only measure them, as well as your other factors, and see whether they affect/correlate with your species abundance. So for example if you were investigating soil temp, you’d measure temp in each

In an ecological study you can’t really control, only measure other factors. The other thing you can do is compare areas that already have these other factors the same, but the factor you’re investigating is different.

Dr Bhavsar But look imgur.com/a/dPmikja These are screenshots of the question, the mark scheme that requires how ( in bold ) the factors are controlled And I put a picture of examiner reports where a student answered the variables to be controlled correctly But wasn’t awarded Mp 8 and 9 because he didn’t say how ( in bold ) the variables are controlled What variables should I control then
