Mg2+ helps the enzyme DNA polymerase  to bind to it’s substrate. This inorganic mineral could be described as a “___________” .    [other examples include iron & zinc]

White light consisting of wavelengths ranging from 400nm to 700 nm is incident upon a diffraction grating having 600 lines/mm. The first order spectrum extends over a range of angles on a screen. Next, the grating is removed and replaced with one having 900 lines/mm. Which of the following statements is correct about the range of angles comprising the first order spectrum?

Two glass panes each 1.0 cm thick are separated by a thin layer of oil with a thickness of 1.0 cm. The index of refraction of the oil is 1.5. Light with a wavelength of 530 nm in a vacuum travels from point A to point B in 0.14 ns. What is the index of refraction for the glass?

A neon bulb emits 1.5 Joules of energy in the form of visible light every second. Taking 600 nm as the average wavelength for the emitted photons, how many visible light photons are emitted per second?

49. Name the structure [49]. 50. Name the muscle [50]. 51. Name the muscle [51].

Use the table above to answer the following question: What is the value of A?

Abortion is a controversial topic. Most people in the US believe abortion should be legal at least under some conditions, but 20% of Americans believe it should be illegal under all circumstances. Suppose we survey a simple random sample of 100 American adults and compute the proportion in the sample who believe abortion should be illegal under all circumstances. Could we use the Z table to find probabilities about the sample proportion of successes? [useZ] Find the probability that p-hat is greater than 0.25. [compute-prob]

The pandemic has affected many aspects of our lives, including manufacturing and delivery of many products. New cars use semiconductor chips, which are now in very short supply, causing the production of new cars to slow down and the prices to go up. Data collected on sale prices of new cars in the US during September 2021 was used to construct a 95% CI for

We would like to estimate the average number of languages spoken by UF students. We believe the standard deviation is around 0.7. How large a sample would we need to take in order to estimate this average to within 0.1 of the truth with 95% confidence?

Most people these days own a smart phone, with iPhones being the most popular. How popular exactly? A study finds that, out of 146 UF students who do have a smart phone, 137 have an iPhone. If we want to construct a 95% confidence interval for the true proportion of UF students who own an iPhone, what should we use for our estimator?
