Answer;
-Fossil evidence
-Comparative anatomy
-Molecular clocks
Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.
Explanation;
-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.
-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
Answer:
The answer is A.
Explanation:
This is the definition of the law of conservation of matter (mass).
The substance that is coded for by a length of DNA is base. The correct option is A.
<h3>What is a base?</h3>
Nucleobases, also known as nitrogenous bases or simply bases, are nitrogen-containing biological compounds that form nucleosides, which are then components of nucleotides, all of which are the basic building blocks of nucleic acids.
The complete question is attached.
The substance that is coded for by a length of DNA is base.
Thus, the correct option is A.

The theory of tectonic plates explains that large convectional currents occuring in the mantle(as a result of magma) are the reasons plates,and so continents,are moved. Note movement occurs in the boundary in between the plates.
Answer:
What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way
Explanation:
Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.
When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.
