The following choices are provided;
- Earthquakes release phosphorus.
- Phosphorus is carried in the rain that was evaporated from lakes.
- Human use of fertilizers releases phosphorus into the groundwater.
- Phosphorus is transpired.
The answer is; Earthquakes release phosphorus
Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
Answer:
Sand
Explanation:
A well should be placed so that contamination from any source moves away from the well and not toward it.
Answer: Ecosystems are made of food chains which are interconnected food webs.
Answer:
A. Increase
B. Increase
C. Decrease
D. Remain fairly constant or change slightly
E. Increase
F. Increase
Explanation:
A. Following deep breathing of room air, the partial pressure of oxygen in plasma will increase because of higher concentrations of oxygen.
B. Following deep breathing of room air, the partial pressure of carbon dioxide in plasma will decrease because because of higher concentrations of oxygen and increase in oxygen uptake by the lungs.
C. Following deep breathing of room air, respiratory drive will decrease of saturation of blood and tissue with oxygen.
D. Following deep breathing of room air, plasma oxygen content will remain fairly constant or change just slightly because the oxygen saturation levels will have been attained.
E. Following deep breathing in and out of a small paper bag, respiratory drive will increase because of the higher levels or increase in partial pressure of carbon dioxide
F. Following deep breathing in and out of a small paper bag, plasma carbon dioxide content will increase as carbon dioxide are produced from exhalation while oxygen is not being replenished.
Answer:
The correct answer is an allele.
Explanation:
The variant form of a gene is termed as allele.Some genes exits as various different forms at a specific position on a chromosome also called genetic locus.
Humans are diploid organism.The diploid nature is due to the presence of two allele at each genetic locus among them one allele is inherited from paternal origin and the other allele is inherited from maternal origin.
