Answer:
Stratosphere
airline pilots prefer to operate in the stratosphere
Answer:
a. every muscle has a varying number of motor units so they can generate different frequencies.
e. each motor unit can innervate a different number of muscle fibers.
Explanation:
Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.
Explanation:
Because Deoxyribonucleic Acid (DNA) determines what the cell does. Ribonucleic acid (RNA) is necessary for protein synthesis: Messenger RNA Transcribes genetic information from DNA into a sequence of basis that is transferred to a ribosome.
Some marine animals live on the edge of sea ice.
Cryosphere is the sphere of all liquids that are solids. Like Ice and glaciers.
Biosphere is everything living on earth.
Answer: Decomposition is a process in which complex organic molecules are converted into simple inorganic forms, which can be easily degraded.
Explanation:
The watermelon is a food source for decomposers. The soft fleshy part get decomposed and degraded easily but the hard thicker rind takes long. The soil decomposers like bacteria, earthworms and fungi will convert the organic matter in the watermelon into inorganic components. This way the matter is converted into a form which can be utilized by the decomposers as a source of energy and some components also improves the quality of soil.
