Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
Answer:
True
Explanation:
This given statement is true.
A dominant allele is the one which overrides the expression of the other allele of the same gene.
For instance,
R is a dominant allele and give red color to flowers while r is the recessive allele and give white color to the flowers
Rr together will give red color to flower because R will dominate r
Answer:
Hughes is a corresponding increase
Girls usually have to help around the house and clean in developing countries, so they probably don't have a lot of time to go to school. Girls are also viewed as "not as capable" as men are.
