Two examples of radioisotopes that can be used are carbon-14 to determine the age of fossils. Second, we can use iodine-131 to treat thyroid disease.
Answer:
The answer choices to this question are:
A) She releases cement particles into a random number of the coral samples.
B) She uses three different types of coral to establish her dependent variables.
C) She treats the coral samples identically with varying levels of carbonic acid.
D) She obtains her coral samples from coral reefs surrounding different continents.
Best Answer is:
A) She releases cement particles into a random number of the coral samples.
Theory:
It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.
i did this question so thats why i know the answer choices
hope this helpsss

Easy:
The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.
The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.
sorry, but this question needed kind of a long answer to be answered correctly.
