Serial dilutions of a food sample could be combined with which of the following methods to estimate the number of viable cells in each dilution a.Inoculation of the diluted samples into tubes with redox dyes to measure redox changes b.Inoculation of the diluted samples into tubes to measure electrical changes c.Inoculation of the diluted samples […]
Phosphofructokinase-1 (PFK-1) is a large enzyme that catalyzes the phosphorylation of fructose 6-phosphate during glycolysis. In fungi, the PFK-1 enzyme is composed of four alpha subunits and four beta subunits. How would you describe the quaternary structure of PFK-1? (2pts) A. aß heterodimer B. aaßs heterotetramer C. a4ßs homotetramer D. α4B4 homooctamer E. a4ßa heterooctamer […]
DIFFUSION AND OSMOSIS LAB REPORT SHEET Name Date_ 1. Brownian movement- define Brownian movement and describe what you observed under the microscope. 2. Solid in a liquid- what happened to the crystal? What happened to the water? Why? 3. Temperature-In which cylinder did diffusion occur more rapidly? Explain by relating the results observed to the […]

Manipulating the Genome and Developmental Commitment A colleague’s laboratory has discovered multiple genetic mediators of congenital heart disease via high-throughput sequencing and bioinformatics analyses. Their work suggests that genetic modifications of thePTPN11gene might be an important risk factor for a subset of patients. You would like to generate a genetically modified Ptpn11“knock-out” mouse to studyits […]
What is rigor mortis and what causes it? Rigor mortis is a chemical change resulting in a stiffening of the body’s muscles following
Describe the major functions and structure of skeletal muscle.Muscles attach to bones directly or through tendons or aponeuroses
Describe the features of a synovial joint and tell which structures support the joint helping to keep the bones in place. The synovial joints move relatively freely. Why?
Describe the functions of red and yellow bone marrow. The stem cells found in healthy bone marrow can be lifesaving for people living with certain autoimmune diseases and cancers.
