Answer:
B. Amplitude: 30cm; wavelength: 110cm
After many years of pressure and possibly heat it will be compressed back into a form of rock such as sediment.
Answer:
At 0 years, an event took place which is known as metamorphosis of igneous rock i.e., formation of igneous rocks from melted magma.
Strontium-90 is a radioactive element which undergoes beta decay to form yttrium-90. It has a half life of approximately 28 years and decay energy of 0.546 MeV. This radioactivity is used by geologist to estimate the age of the rock, fossils, meteorites etc. Other radioactive elements used by the geologists are carbon-40, potassium-40 etc.
Radiometric clock is set when the rock was formed in the past i.e., the moment when an ingenious rock was solidified from molten magma.
Answer:
The <em>answer </em>is option A i.e "32%". According to Chargraff's rule, Number of purine (adenine+guanine) = Number of pyrimidine (cytosine+thymine). Hence, the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Answer: Vasodilation of the arteries lowers blood pressure and decreases the force that the heart muscle needs to exert to pump blood., the cell signaling mechanism begins when $NO$ diffuses into the smooth muscle cells of the blood vessel and activates guanylyl cyclase.
