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:
<em>When a queen gets old or weak and slows her production of queen substance, she is generally replaced by a new queen. New queens are also produced in colonies about to swarm. Virgin queen bees take what is known as a "nuptial flight" sometime within the first week or two after emerging from the pupal chamber.</em>
Answer: Muscular system because it is a complex body system, the others are organs in cells
The process that transports
solutes, including many drugs, into the tubular fluid is called tubular
secretion. Under this process, there is transfer of materials from peritubular
capillaries to the renal tubular lumen and the secretion is caused mainly by
active transport and passive diffusion.
