List and describe the steps of the evolution of eukaryotic cells on Earth, known as the endosymbiotic theory.

Which of the biomolecules is incorrectly matched with its building block?

A cylindrical container with a 40-cm height and a 2.0-cm diameter contains helium gas, which has density 0.1785 kg/m3. A piston on one side of the container moves inwards until the helium’s density is 0.22 kg/m3. What is the new height of the cylinder?

Marie and Maria each send a spinning uniform disc towards the center of an axle. Marie’s disk has a mass of 0.5 kg with a radius of 15 cm and is spinning about the axle at a rate of 120 rpm. Maria’s disk also has a mass of 0.5 kg, but a radius of 20 cm, and it spins in the same direction as Marie’s at a rate of 150 rpm. The two discs then collide and stick together. What is their final rotational speed in rad/s?

A group of local troublemakers send a 600 kg cart crashing into an innocent cabbage stand at a speed of 16 m/s. If the average force on the wagon during the collision is 9500 N, how long does it take for the cart to stop?

As you have read so far, eukaryotic cells are much more complex and include many more internal structures than prokaryotic cells. Please list and describe the functions of at least 5 internal structures found in a eukaryotic cell.

Consider an ADC system that represents voltages from -9 V to 7 V with signed 6-bit results. Assume that the graph of the ideal transfer function for the ADC passes through the point , not

An anion is formed when

The restoring force a bow provides to an arrow as it is pulled back can be modeled as a spring force. The archer Gila “nocks” an 18-g arrow by pulling it back a distance of 45 cm. Gila fires the arrow horizontally from a small cliff with a height of 12 m, and when the arrow reaches the bottom, it has a speed of 63 m/s. What is the effective spring constant of the bow as Gila nocks the arrow?

Deadeye Martin fires a 18-g arrow at a speed of 40 m/s at a 150-g apple tossed straight into the air by his friend Jaquette. If the arrow arrow travels straight through the apple at the peak of the apple’s trajectory, and the apple’s speed is 1.8 m/s after the collision, what is the speed of the arrow immediately after hitting the apple?
