The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 100 billion neurons.
The answer is Blood clots
Answer:
Photorespiration
Explanation:
RuBisCo is the enzyme that catalyzes the first reaction of the Calvin cycle which in turn is a rate-limiting step. Photorespiration is the process during which the enzyme RuBP carboxylase/oxygenase (RuBisCo) catalyzes the reaction between oxygen and ribulose 1,5-bisphosphate to form 3-phosphoglycerate and 2-phosphoglycolate.
These two products are useless for the metabolism of cells. Photorespiration occurs since the RuBisCo enzyme has an affinity for both CO2 and oxygen. When CO2 is not available, as it occurs when plants close stomata during hot dry days to prevent water loss, photorespiration takes place. Therefore, stomatal closing in C3 plants to prevent water loss promotes photorespiration.
Answer:
Most sedimentary rocks are formed in level layers. Therefore, the occurrence of tilted rock layers is evidence of mountain building. ... Tilting can also result when rocks are pushed upward, or uplifted. In some areas of the world, rock layers are so severely tilted that they may be bottom side up. Layered rocks form when particles settle from water or air. Steno's Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. ... Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata.
Answer:
The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation
