. It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest
MatroZZZ [7]

Answer:

       The right answer to this question is option A) island forms and mainland forms descended from common ancestors.

       It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.

       A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.

Vilka [71]
<h2>Ecological Footprint - Option C</h2>

An ecological footprint is determined by measuring the rate of water used. The Ecological Footprint is determined by following how much biologically prolific field it needs to consume a population's carbon dioxide radiations and to produce all the means it absorbs.

A country's consumption is measured by summing imports to and deducting exports from its nationwide generation.

A Xw+m+Xwm female was mated to a XwmY male. Out of 1000 total F1 progeny there were 230 flies that were otherwise wild type with
deff fn [24]
In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.
\frac{230+240}{1000}=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>
