Name two types of evidence used to support the theory of evolution. explain how scientist use each type of evidence to provide s
joja [24]

Answer:

There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera

Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.  

For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.  

It shows divergent evolution and supports that these organisms have evolved from a common ancestor.

Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.

For example:

  • The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
  • Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.

tigry1 [53]

Answer:

Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.

Explanation:

The air travels through the respiratory system during inhalation in the next order:

  1. <em><u>Nasal cavity:</u></em> You inhale air into your nose.
  2. <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
  3. <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
  4. <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
  5. <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
  6. <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
