When dna molecules are heated, the two strands at a particular temperature and that temperature is called the dna's melting point. some dna molecules seperate at lower temperature while other dna molecules take more energy to spilt or "melt" and these seperate at higher temperatures. scientists have found that dna stands that have more g-c pairs (rather than a-t pairs) are harder to melt and require more energy to melt. why do you think that is?

i think the answer would d

i won't lie i don't know so go online and ask google thats what i do

idk and i also need to know where are those bio brainy acts lol

answer;

-vessels in the chest

the diagnosis of angina pectoris literally means "vessels in the chest"

explanation;

-angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease.it is the chest pain due to an inadequate supply of oxygen to the heart muscle. the pain is typically severe and crushing, and it is characterized by a feeling of pressure and suffocation just behind the breastbone.

agina pectoris is caused by reduced blood flow to your heart muscle. the blood carries oxygen, which the heart muscle needs to survive. when the heart muscle isn't getting enough oxygen, it causes a condition called ischemia
