The biggest difference in gene functions between unicellular and multicellular eukaryotes is in the proportion of genes for:

Most genes of an organism:

The chloroplast genome includes genes for products involved in gene expression, such as RNA polymerase and ribosomal proteins. 

(5 points) Gastric acid is produced by parietal cells in the stomach. Its secretion is a complex and relatively energetically expensive process that acidifies the stomach with HCl while maintaining a neutral cytosolic pH. (1) Explain the process of acidifying gastric fluid and the function of each of the five transporters in achieving the acidic pH of the stomach. (2) Define each transporter based on the information discussed in class.

The number of independent protein complexes that can be formed by an organism is known as its:

Teachers can systematically document their students’ literacy development by using clearly defined sets of traits or behaviors and by jotting down any spontaneous observations about the student behavior on index cards, sticky notes, or address labels. This is known as _______.  

T / F  The levels for interaural attenuation are different for insert earphones and supra-aural earphones. 

What is “program music”?

Match the examples below with the corresponding study design.

Using the patient responses listed below, calculate the threshold for stimuli starting at 70 dB HL (Trial 1). “Positive” indicates that the patient responded to the stimuli while “negative” indicates that they did not respond to the stimuli. You may plot the responses on the handout to help you find threshold but it is not required. (Remember your units in the answer).
