[Chapter 10] In the figure below, we see the transition from austenite (point a) through the
eutectoid point to pearlite (point b). However, other microstructures (bainite, martensite) can also
be formed from austenite through the same eutectoid point. How is this possible, given that they
are not on the diagram below?

This diagram does not show transformations below 400°c.
Austenite must transform to pearlite before it can form bainite or
martensite.
O Bainite and martensite are non-equilibrium microstructures and this is an
equilibrium phase diagram.
This is an outdated diagram.

- Cell respiration and photosynthesis are distinct metabolic processes that take place in the mitochondrion and chloroplast, respectively. While these two processes are separate, they share things in common. When one looks at the overall equations for cell respiration and photosynthesis, one sees how they are near opposites in terms of the starting and ending materials. In 300-400 words, describe this “near opposite” relationship between cell respiration and photosynthesis. What are the starting and ending materials in each process, and what kind of energy transformation is taking place?arrow_forwardWhat macromolecule would NOT be created if all chloroplasts were removed from a plant cell? *arrow_forwardRefer to the graph. Mustard plants were grown under 16 hours (hour 0 to 16) of light followed by 8 hours (hour 16 to 24) of dark for several weeks.

- Stanley Miller and Harold Urey created an experiment that simulated conditions on early Earth. Building on the results from this experiment, scientists decide to test the effect of varying the initial amount of NH3 on monomer formation. They set up the same simulation with the exception of starting with three different concentrations of NH3. The amounts of H2 and CH4 are kept constant in each treatment. They run five simulations per NH3 concentration, as well as five simulations that only have H2 and CH4. Why did the scientists run five simulations with no NH3? O To test the hypothesis that early Earth's atmosphere contained no NH3. O This serves as the control group. ) To test the effect that H2 and CH4 have on monomer formation. O NH3 is a controlled variable.arrow_forwardStanley Miller and Harold Urey created an experiment that simulated conditions on early Earth.
