in a compost pile that is maintained
Answer:
b. by increasing the heart rate
c. by increasing the respiratory rate
Explanation:
Increased activity of skeletal muscles would require an increased supply of oxygen to these cells to sustain the muscle contraction. Muscle cells perform aerobic cellular respiration in the presence of oxygen and produce ATP molecules to be used during muscle contraction. Therefore, there is an increase in heart rate to pump sufficient blood to the skeletal muscles which in turn ensures enough supply of oxygen. Also, there will be an increase in the respiration rate to inhale the required oxygen.
As a rule of thumb, a person will eliminate one average drink or . 5 oz (15 ml) of alcohol per hour. Several factors influence this rate. The rate of elimination tends to be higher when the blood alcohol concentration in the body is very high.
Answer:
c
Explanation:
because in populated areas people are independent
Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence:
- fit of the continents
- paleoclimate indicators
- truncated geologic features
- and fossils.
<h3>What is Alfred Wegener's theory of continental drift?</h3>
The existence of Pangea was first suggested at the beginning of the 20th century by the German meteorologist Alfred Wegener, which created a huge controversy among the scientific class of the time.
<h3>Paleoclimate indicators</h3>
Pangea is the name given to the supercontinent that made up the Earth's surface from the Permian to the Triassic periods. This single mass was also bathed by a single ocean, called Panthalassa. The separation of Pangea, which gave rise to the configuration of the continents as we know them today, began 230 million years ago.
With this information, we can conclude that Wegener also noticed that there were major mountain building event sin the northern Appalachians and in northwestern Europe of the same age.
