Answer:
Cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx.
Explanation:
Vertebral column or spine is made of a total of 26 vertebrae in adults. Starting from the upper part, it has 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, one sacrum, and one coccyx.
The coccyx is made of four fused coccygeal vertebrae. Likewise, the sacrum consists of five sacral vertebrae that are fused during development.
Answer:
If the boundary between the cold and warm air masses doesn't move, it is called a stationary front. The boundary where a cold air mass meets a cool air mass under a warm air mass is called an occluded front. At a front, the weather is usually unsettled and stormy, and precipitation is common."
Explanation:
Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.
Hope this helps, have a lovely day :)
Robert Hooke is the first person to observe cells as microscopic structures.
He was of British descent and, fun fact, he discovered cells by looking at a sliver of cork under a microscope lens (although the 'fun fact' is heavily simplified).
