Answer:
Tissue
Explanation:
The levels of organization go as follows:
Atom - the building blocks of all living and nonliving material
Molecule - two or more atoms that join together in chemical bond
Organelle - two or more molecules working together to perform a particular function in a cell
Cell - the smallest unit that exhibits all of the characteristics of life
<u>Tissue - two or more cells that work together to perform a particular function</u>
Organ - two or more tissues that work together to perform a particular function
Organ System - two or more organs that work together to perform a particular function
Multi-Celled Organism - two or more organ systems that work together
Coral bleaching is essentially when a coral turns white because the temperature is too hot for it to survive. It will continue to occur as the temperature keeps getting higher because of global warming. All corals might die
Answer: A
Explanation:
The Big Bang theory is basically how the world was created, or sometimes known as the sun exploding. This would be the same example of a balloon being popped.
Answer:
Breathing rate is most likely to increase if the blood level of carbon dioxide increase.
Explanation:
Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.
