In 2006, scientists found a fossil that seemed to have fish-like scales and four legs. It also had a bone structure in its neck
lianna [129]

Answer:

Option-C

Explanation:

Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.  

The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.

The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.

Thus, Option-C is correct.

What is Grave's disease?
I am Lyosha [343]

Answer:

Graves´ disease is an autoinmmune disease that is caused when the immune system attacks the cells of the thyroid gland, which leads to an overproduction of the hormones secreted by the thyroid gland. This constant attack and destruction on the part of the immune cells causes the thyroid to increase in size, a condition that is commonly known as hyperthyroidism.

Hyperthyroidism can become a really serious issue because the excessive production of the hormones of the thyroid gland will increase the metabolic activity of all parts of the body and can, if left untreated, cause such serious conditions as blood clotting problems, type 1 diabetes, among others.
