<h2><u>Heart and lungs:</u></h2>

The upper chamber of the heart is called atrium and lower chamber of the heart is called ventricles.

The blood circulation in the heart is basically under the functioning of three blood vessels namely:

<h3><u>Arteries: </u></h3>
  • They start with the aorta, the huge vein leaving the heart.
  • Veins divert oxygen-rich blood from the heart to the majority of the body's tissues.
  • They branch a few times, decreasing and littler as they convey blood more remote from the heart.
<h3><u>Capillaries: </u></h3>
  • These are little; flimsy blood vessels that associate the arteries and the veins.
  • Their dainty dividers permit oxygen, supplements, carbon dioxide, and other waste items to go to and from our organ's cells.
<h3><u>Veins: </u></h3>
  • These are the blood vessels that return blood to the heart; this blood needs (oxygen-poor) and is wealthy in waste items that are to be discharged or expelled from the body.
  • Veins become bigger and bigger as they draw nearer to the heart.
  • The unrivaled vena cava is the huge vein that brings blood from the head and arms to the heart, and the second rate vena cava brings blood from the mid-region and legs into the heart.

In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for
AVprozaik [17]

Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

In this case; the round pea shape is dominant to the wrinkled shape;which means the phenotype of round shape will be expressed when we have both homozygous dominant (RR) and heterozygous (Rr), while the wrinkled shape will be expressed by homozygous recessive (rr).
