Describe how a planar (2D) linkage with respectively 1 DOF, 2 DOF, 3 DOF will move. What does it mean to have a linkage with more degrees of freedom than the dimension of space it lies in?
Since 6 total DOF possible for rigid body in space ( 3 rotational and 3 translational) so it is normal to have more DOF than dimension of space it is lying since each axis contributes 2 DOF ( 1 Rotation & 1 Translation) It simply means it can have extra freedom to rotate or translate in available directions. If it were mechanism then we would work on to control unnecessary DOF so that desired motion in particular direction can be achieved.

You find a graph with five vertices of degrees 3, 1, 4, 4, 2, respectively. How many edges does it have? Be careful, wrong answers have negative weights. Select one: a. 28 b. 14 c. 7 d. 12 e. 5
With regards to population genetics, how does linkage disequilibrium work? If different loci are very close together, alleles might be inherited together more often than expected. What does that mean with regards to frequency of those alleles within a population of perhaps 100 individuals (animals)?
1. What do genetic linkage maps tell us about phenotype? 2. How can genetic linkage maps show that selection is acting on a population?

This makes it impossible to run a paired t-test. Rather than start over: a) Compute the mean and standard deviation of the two samples (2-pts) b) Compute the two sample t-statistic (2pts) c) How many degrees of freedom do you have(3pts)? d)...

Derive the equation for their electrie potential at a location (x, y) in 2D space. Assume that reference electric potential is at oo and is equal to zero Using MATLAB: i. Plot the electric potential V(x. y) in a 2D domain that ranges from -5...
31. In 2-3 sentences, describe how bacteria move when using a single flagellum during swimming motility. Your description must include the rotation of the flagellum and the corresponding name for that aspect of the motion. 4 pts 31.

A concentration gradient affects the direction that solutes diffusion. Describe how molecules move with respect to the concentration. How does size affect the rate of diffusion? Does polarity affect the rate of diffusion? Explain your answer. If a piece of celery is placed in a glass of pure water, are the celery cells hypertonic, hypotonic or isotonic compared to the water? In which direction will water move? What is the water potential of pure water? Why don’t red blood cells...
