Answer:
D
Explanation:
Crude oils, shale, and natural gas are some of the fossil fuels formed in this way. They are specially formed when vast amounts of algae die and sink to the bottom of the oceans over time and accumulate with sediments. They become buried under vast layers of sediments that apply high pressure. Over time, the high pressure and temperature turn the organic molecules into fossil fuels.
Answer:
C. the medulla oblongata, which is in contact with cerebrospinal fluid, monitors pH and uses this measure to control breathing.
Explanation:
The central chemoreceptors are located near the medulla inside the blood-brain barrier. When CO2 in cerebrospinal fluid increases, pH of the fluid lower (because CO2 becomes hydrated to carbonic acid). Change in pH stimulates the central chemoreceptors to activate respiratory centers which will increase the respiratory rate and depth of breathing.
Answer: Im pretty sure it´s D.
Explanation: Manatees like to raise and feed their young in safe places so if we increase the amount of protected areas their population is more likely to increase.
Hope this helps!
Answer:
<em>The fungus can be transmitted through contact and the fungus is deadly to bats.</em>
Explanation:
David Blehert was a scientist who had received a PhD in the field of bacteriology.
David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.
David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
