Paleontology, the study of fossils, supports evolution because the discovery of old life forms shows how new life evolved.
Answer:
A. Intracellular Thirst
Explanation:
There are two types of thirst and intracellular thirst and extracellular thirst. Extracellular thirst (dehydration) can be ruled out as it only requires water and salt to regenerate blood, at it's correct osmality. On the other hand, intracellular thirst (dehydration) can be corrected by drinking water alone. Therefore, the answer to this problem is intracellular thirst due to thirst for plain water.
Oxygen is a vital element within cellular respiration. An intrinsic part of the cellular respiration cycle is the transfer or electrons through the electron transport chain, and at the end of it exists the mitochondria, in which electrons are donated to the Oxygen and combine with hydrogen ions to form water.
essential amino acids.
the "essential" refers to it being necessary to derive them from the foods we eat, but in fact the amino acids that the body produces are just as essential to the proper functioning and health of our bodies.
Lactic acid formation occurs in B) The yeast cell.
