Answer:
This process is called transcription
Explanation:
This is where DNA is copied to make a RNA molecule.
My 2 cents below, I tried to think through the other ones:
A. Yes, because an amino acid change has occurred.
(A gene mutation occurred, not an amino acid change)
B. Yes, because all mutations change the resulting protein.
(Sounds correct. Gene -> mRNA -> protein)
C. No, because the amino acid sequence has not been changed.
(The gene mutation means the amino acid sequence <em>has</em> changed)
D. No, because mutations in the DNA do not affect the mRNA sequence.
(They do so)
B, cooling and solidification of magma.
Answer:
Stable angina
Explanation:
Stable angina is the most common type of angina and therefore, is called typical angina pectoris characterized by a burning heavy and squeezing feeling in the chest (substernal , shoulder ). It is caused by the reduction of coronary perfusion due to a fixed obstruction produced bt coronary atherosclerosis.
The heart becomes vulnerable to ischemia whenever there is increased demand, such as that produced by physical activity ,emotional excitement , or any other cause of increased cardiac workload.
Typical angina pectoris is promptly relieved by rest or nitroglycerin.
As in the above mentioned scenario, Steve hill feels substernal pain after walking from the car thus increasing work load on heart and this pain relieves with rest, this is a characteristic finding of stable angina.
