Answer:
A beaker
Step-by-step explanation:
Specifically, I would use a 250 mL graduated beaker.
A beaker is appropriate to measure 100 mL of stock solution, because it's easy to pour into itscwide mouth from a large stock bottle.
You don't need precisely 100 mL solution.
If the beaker is graduated, you can easily measure 100 mL of the stock solution.
Even if it isn't graduated, 100 mL is just under half the volume of the beaker, and that should be good enough for your purposes (you will be using more precise measuring tools during the experiment).
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies
Answer: Darwin spent five years on his journey as the ship's naturalist on the H.M.S. Beagle. Some of the evidence he used to support his theory was based on fossils he saw in South America. In the 1800's, most people were of the belief that the world was only a few thousand years old and that organisms that existed were unchanged since the beginning. However, the fossil evidence that he found showed giant versions of modern animals that no longer existed. It pointed to the idea of an ancestor that may have changed over time to the modern life forms that exist today. He also noted that the most likely place that the life forms on the Galapagos Islands could have come from originally, was Equador which was about 600 miles away. Differences in environment, food supply, temperature, etc. would put different pressures on animals on each of the various islands. Over time, natural selection would favor those best adapted for their various environments and after two million years, you have many different species that have evolved from common ancestors in Equador. The most famous of course, are Darwin's finches. Also famous are the different giant tortoises that vary by shells, size and habits, from island to island. Other famous animals include iguanas. One is extremely unique, the marine iguana, which is the only marine iguana in the entire world.
