You are studying a population of pea plants which flower colors ranging from white to dark pink. You selected only those plants with the darkest pink flowers to use in cross-pollination. Once you plant the seeds and grow your new generation of pea plants, what would you expect to see

The question is incomplete as it does not have the options which are:

You would see disruptive selection.

The relative numbers of flower colors would remain unchanged.

The relative numbers of white flowers would increase.

Your results would show directional selection.

Your results would show directional selection

Explanation:

In the given question, the pea plants produce a range of flower color from white to pink and then dark pink. If we will grow the plants with dark pink flowers than the plants in that area will have dark pink flowers.

In evolutionary terms, this can be suggested that the growing the plants with by humans is a natural force that is favoring the extreme color of the flower which is dark pink and natural selection will be observed.

In this scenario, since the dark pink color is the extreme color which is favored by the humans to grow therefore the directional way of natural selection is acting which is characterized by the favor of only one extreme phenotype.

Thus, the selected option is correct.

from almost the creation of the first true maps of the earth, people started seeing how continents would be able to fit together.   in particular, people noticed that south america fits almost exactly into africa.

you should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets.   and so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.

get the whole story here…

it is now known that most of the major continental masses can be fit together in a jigsaw process.   in fact we now know that the continents were indeed once all joined together as one land mass – the supercontinent of pangaea.

if you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well.   what you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom.   this means that the map distorts the true shape of the earth’s land and oceans as you love closer to the poles.     some other map projections distort less, but have the map shape looking like segments of an orange.   see here for a range of map projections.   check out the way greenland changes size in each!

what is more remarkable, is the next piece of evidence when added to the shape of continents.

location of mountains and fossils

what is remarkable, when you reassemble all the continents together, the ancient mountain ranges (many now eroded to their cores) and the location of rock types and fossils all match up.
