2. Adaptation is an organism changing to better themselves in a certain environment.

3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.

4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.

6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

Using no more than 14 propositions, list the functions, structure, and distribution of the lymphatic vessels and describe the me
sveticcg [70]

The lymphatic vessels are thin-walled valvular structures, composed of lymphangions, which carry the lymph from the tissues, via the lymph nodes, to the bloodstream. For this reason, they are analogous to veins and venules.

The lymphatic network is present throughout the body with the exception of the central nervous system and non-vascularized tissues.

It is separated in two circuits: one for the upper right quarter of the body, and one for the rest.

The lymphatic channels join together to form lymphatic vessels more and more voluminous.

Finally, The lymph is drained by two large collectors:

* The right lymphatic canal

* The thoracic duct.

All lymphatics thus end up in the upper vena cava system by two separate circuits.
