The embryos of two different organisms are observed to have similar features. What is the most reasonable conclusion that can be drawn from this observation?The organisms will share these same features as adults. These organisms will have the same role in the same habitat. These organisms will take the same amount of time to develop. These organisms are related by a shared common ancestor.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
