How did Miller’s classic experiment relate to the origin of life?
Expert Solution & Answer
Summary Introduction
To explain: The way in which the classic experiment by Miller relates to the origin of life.
Introduction: In 1953, Scientist Stanley Miller and Harold Urey set up an experiment with conditions resembling those present on the early Earth. The possibility of organic compound formation was investigated under simulated conditions in this experiment.
Explanation of Solution
Organic molecules were synthesized from inorganic molecules in the classic experiment of by two scientists Harold Urey and Stanley Miller. They used a mixture of gases such as hydrogen, methane, ammonia, and water vapor in his experiment and passed sparks through this mixture of gases. This experiment is commonly known as Urey-Miller experiment. A number of compounds were identified in the mixture; many of them were found to be organic compounds. The result of the classic experiment denotes the formation of macromolecules from micromolecules.
In Urey–Miller experiment, organic molecules, such as amino acids from nitrogen, carbon, oxygen, and other inorganic elements were synthesized. This simulated the physical and chemical conditions at the time of origin of life billions of years ago.

In a population of Jackalopes (pictured below), horn length will vary between
0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick
Jackalopes that have horn lengths around 1.75 feet to breed as this appears to
be the optimal length for battling other Jackalopes for food. After a round of
breeding, you measure the offsprings' mean horn length is 1.67. What is the
heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4
pts)?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree
growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a
forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence
Repeat. Complete the following table that compares the two DNA replication events in terms of the
primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value
for the number of copies of the template DNA after one S phase in one cell and after the lab has
completed the PCR reaction.

Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar.
