Answer:
Cynognathus fossils were important to Wegner's theory because they were found on lands now separated by a wide ocean.
Explanation:
Wegner used the fossil of cynognathus as evidence to prove his continental drift hypothesis. Cynognathus are reptiles which lacked the swimming ability. These reptiles survived in the land before separation in live form along with other organisms surviving side by side.
Later due to certain natural phenomenon these reptiles died and the land got separated by a wide ocean. The fossils of cynognathus reptiles are now found in the lands that are separated by wide ocean.

Explanation:
Schamberg's disease is the pathological condition that allows lymph to leak from the blood capillaries, it causes no other symptoms beside skin discoloration and itching. The condition is caused by inflammation of capillaries near the surface of skin and subsequent leaking of blood cells into surrounding tissues.
So, the Lymph found in this patholgical condition is a fluid that circulates the entire body in the lymphatic system. The lymphoid organs include (the spleen, lymph nodes, bone marrow, thymus and lymph tissue) . These lymph nodes are small, bean-shaped structures which produce and store cells, specialized in fighting infections.
In the spleen (an organ in the upper left abdomen, filtration of these blood and disposal of worn-out blood cells occurs ), Hence, provides a reserve supply of blood.
However, Fluid in the spaces between the tissues are called interstitial fluid (tissue fluid). They provides the cells of the body with nutrients (via the blood supply) and a means of waste removal.
As such, Lymph is formed when the interstitial fluid is collected through tiny lymph capillaries, which are located throughout the body. It is then transported through lymph vessels to lymph nodes, which clean and filter it. Lymph then flows on to the lymphatic ducts, before emptying into the right or the left subclavian vein, where it mixes back with blood.
Answer:Light-sensitive cells in the retina at the back of our eye allow us to see. The human eye has two types: cones and rods. Rods are extremely efficient; a tiny amount of light can trigger them. They are responsible for our night vision

Hawaii's Big Island:
Mountain barriers play a significant role in modifying the air masses and topography affects the distribution of precipitation.
The orographic effect takes place on Hawaii's Big Island (i.e) the rising air makes the windward side of the mountains rainy and leeward side of the mountains dry.
Island of Maui:
In the Island of Maui, the high mean of rainfall is found on the windward side of the mountain slopes and the low mean of rainfall is found on the leeward lowlands and on upper slopes of the highest mountains.
