We explain this puzzle-piece-like build as proof of tectonic plate shifting. As magma inside the earth moves, so do the continental plates on top of the magma. The continents used to be fused together in one larger continent called Pangea. Over the course of 1000s of years, the plates have shifted.
tldr: tectonic plate movements cause this phenomena
Extrusion <span>is not a process involved in the formation of sedimentary rock</span>
Answer:
C
Explanation:
Behavioural reproductive Isolation. This is the type of behaviour isolation that do not allow some members of a population to mate with the others. It might be due to how they find and choose mates. Some species have very unique rituals and behavior that has to take place before reproduction can occur so most of the time it is a form of pretty-zygotic barrier that happens before reproduction can happen.
Explanation:
The equation that shows the equilibrium reaction of carbon dioxide in the blood is the following one:
<h3>
CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3><h3 />
This equation describes the bicarbonate buffer system which regulates the pH of the blood.
- During hypoventilation, the CO₂ produced by the cells through metabolism is not released fast enough, so CO₂ levels in the blood increase. In this situation, the equation shifts towards the right, and an excess of protons is produced, therefore decreasing the pH and causing acidosis.
- During hyperventilation the breathing is very rapid and CO₂ is exhaled from the body at a very fast rate. In this situation, the CO₂ levels in the blood decrease, the equation shifts towads the left and the concentration of H+ thus decreases, causing alkalosis.
The right answer is 28 years.
The half-life, or period of a radioactive isotope, is the time required for half of the nuclei of this isotope initially present to decay naturally.
One gram of pure 90 strontium has a radioactivity of 5.11 TBq. Its beta radiation is not penetrating, which makes it difficult to measure when it is in the soil or a matrix. It is very harmful when the particle is inhaled or ingested.
