Answer:

  • <u>Natural selection and adaptation:</u>

Living organisms are always in the process of adaptation to the surroundings or the environment in which it lives from one generation to another. As, over centuries men are also subjected to evolution.

  1. <u>Men living in the high grounds and those living in the lower altitudes:</u>We can analyze the case of people living in the different regions across the globe. As there are difference among the skin tone, there heart rate and the instinct to survive in harsh conditions. Because, if a generation of people migrates from a lower altitude region into a area of higher altitude then there will be an evolution or set of changes inside the living being body mechanism or more over cellular activities. And thus there kids will have a more capacity in terms of enduring the low rate or level of oxygen in the higher altitudes regions.So, it can be analyzed over the period of one and half decade of time duration, to see how the different individuals evolve through time as per the conditions provided to it.
  2. While there can be also the changes seen in the skin tone of the people who's ancestors have migrated long before they were born in the high altitude areas.

<u>Answer:</u>

<em>Darwin was a British naturalist UN agency planned the idea of biological evolution by survival of the fittest. </em>

In <em>living organisms, several characteristics are transmissible, or passed from parent to offspring</em>.

(Darwin knew this was the case, even supposing he didn't understand that traits were transmissible via genes.)

Organisms are capable of manufacturing a lot of offspring than their environments will support.

<em>Thus, there's competition for restricted resources in every generation. </em>

The offspring in any generation are slightly totally different from each other in their traits<em> (colour, size, shape, etc.), and lots of of those options are genetic. </em>

<em>To make survival of the fittest a lot of concrete, let's take into account a simplified, theoretic example.</em>

During this example, <em>a gaggle of mice with genetic variation in fur colour (black vs tan) has simply touched into a brand new space wherever the rocks are black. </em>

<em>This surroundings options hawks, that prefer to eat mice and may see the tan ones a lot of simply than the black ones against the black rock. </em>

Because the hawks will see and catch the tan mice a lot of simply, a comparatively giant fraction of the tan mice are consumed, whereas a way smaller fraction of

<em>If we glance at the quantitative relation of black mice to tan mice within the living ("not-eaten") cluster, it'll be more than within the beginning population </em>

NNADVOKAT [17]

There are three ways you can solve this problem:

1.- You can guide yourself through knowledge, and therefore know the answer. There isn´t much to explain here.

2.- You can eliminate obvious options such as sarcodina or apicomplexa. Euglenoid isn´t an extremely obvious removal since it has a flagela, which can be mistook by a hairy-structure. But, if you do things correctly, obtaining your answer wont be a problem.

3.- You can do an etymologic-guess, which works really well in biology. If you guide yourself this way, you´ll bump into the answer quickly --> "cilio" means hair and according to the description the specimen was covered in hairy structures.
