Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.

1 answer:

3 0

Burning fossil fuels will produce carbon dioxide which is a global gas causing global warming . Global warming causes the sunlight to be trapped in the atmosphere of the earth which will cause the temperature of the earth to increase. so the polar ice will melt and the sea level will increase

Which organelle would have a protein fingerprint most similar to the cell membrane?

vaieri [72.5K]

All cells have a protective covering known as cell membrane. In plants, the cell membrane is further protected by another layer called cell wall. All the organelles present inside the cells are membrane bounded structure.
Cell membranes are made up of phospholipid bilayer with extrinsic and intrinsic proteins. From the studies on the plasma membrane structure, it was found that the protein fingerprint of MITOCHONDRIA and CHLOROPLAST are most similar to the cell membrane.

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>
