The correct answer is C, The large passageways into which the minor calyces empty are the renal pelvis.

The renal pelvis is a crucial anatomical structure within the urinary system, specifically associated with the kidneys. It serves as a funnel-shaped reservoir located at the upper end of the ureter, the tube responsible for carrying urine from the kidneys to the bladder. The renal pelvis collects urine produced by the kidney's functional units, known as nephrons.

Situated within the kidney's innermost region, called the renal sinus, the renal pelvis receives urine from several minor calyces, which are small cup-like structures that gather urine from individual nephrons. The pelvis then funnels the urine towards the ureter, facilitating its transport to the bladder for eventual elimination.

Answer: Primary producer > primary consumer > secondary consumer > tertionary consumer.

Explanation: Primary producers(plants) get their energy from the sun then when a primary consumer (organism that eats plants; herbivores) eats the primary producer it collects that energy with it. Then when the primary producer is eaten by the secondary producer( carnivores that eat smaller animals; such as wolves,crow,hawks etc.). The tertionary consumer eats the secondary consumer.(tertionary consumers are larger carnivores) therefore energy gets passed down the line all the way to the tertionary consumer.

Answer: The energy flow is unidirectional in nature.

Explanation: When these herbivores are ingested by carnivores of the first order (secondary consumers) further degradation will occur. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Moreover, in a food chain, the energy flow follows the 10 percent law.

The force that caused the rubber blue ball to roll down the ramp is gravity. When Kendrick held the ball halfway up the ramp and then released it, the force of gravity began to act on the ball and it started to roll down the ramp.

A ramp is an inclined plane that reduces the amount of force required to move an object to a higher level. The force of gravity, which is an attractive force between any two objects in the universe, acts on objects in the direction of the center of the Earth.

This force causes objects to fall toward the ground. When the rubber blue ball was released from the midpoint of the ramp, it began to move in the direction of the force of gravity, which caused it to roll down the ramp. The force of gravity was able to overcome the ball's inertia and caused it to accelerate down the ramp. Once the ball rolled off the end of the ramp, it continued to move forward due to its inertia.
