yan [13]
The correct answer is C. It is a sudden change that causes species to become extinct.

This answer is not correct because evolution occurs over a long period of time, as evidenced by the theories that describe its timeline (including gradualism and punctuated equilibrium). Additionally, evolution does not always involve the extinction of a species, but it can.

Hope this helps!

<h2>Multi-Chambered Heart </h2>

Explanation:

  • The four-chambered in warm blooded mammals like frog's have three chambered of heart.
  • Other warm-blooded creatures, consume a great deal of vitality and need a lot of oxygen.This change bears the turtle's body blood that is somewhat more extravagant in oxygen than the frog's.  

Advantages of fish-  

  • The heart doesn't require extra chambers past the initial two.
  • Fish and different creatures with 2-chambered hearts, along these lines, have less difficult circulatory frameworks than creatures with lungs and therefore, 3-and 4-chambered hearts.  

Advantages of Amphibians-

  • The amphibians have a three chambered of the heart which to be very helpful to  amphibians of land and water.

Advantages of Reptiles-  

  • The  reptiles have a three-chambered heart comprising of one ventricle and two atria.
  • The chamber called the correct chamber gets d<em>eoxygenated, or "spent," blood coming back from the body tissues.  </em>

Advantages of Mammals-

  • The four-chambered heart of feathered mammals and well evolved creatures advanced freely from a three-chambered heart.  

Advantages of Birds -

  • Birds like mammals , similar to vertebrates, have a 4-chambered heart (2 atria and 2 ventricles), with complete division of oxygenated and de-oxygenated blood.
  • The correct ventricle siphons blood to the lungs, while the left ventricle siphons blood to the remainder of the body.
