Are you referring to land building (where when coral dies it contributes to reef) calcification (coral and other animals are calcifying due to pollution) or polyps (how coral grow)
Answer:
The amoeba excretes waste through<u> Contractile Vacuole</u> while a sparrow excretes waste through <u>Cloaca</u>.
Explanation:
In some unicellular eukaryotic organisms (e.g., amoeba), cellular wastes, such as ammonia and excess water, are excreted by <u>exocytosis</u> as the <u>contractile vacuoles</u> merge with the cell membrane, expelling wastes into the environment.
Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the<u> cloaca</u>. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.
Answer:
The correct answer is: C.
Explanation:
- The given situation is the example of a Reflex Action.
- Reflex action can be defined as an action shown in response to a sudden stimulus.
- The CNS or the Central Nervous System is comprised of the Brain and the Spinal Cord which receives the Sensory impulses from the Receptor organ, integrates or decides on the response which needs to be provided and then sends the Response impulses to the Effector organ.
- The PNS or the Peripheral Nervous System is comprised of the sensory and motor neurons those are responsible for connecting the Sensory organ and the Motor organ to the CNS, respectively.
- In the situation, Sarah's eyes perceives the ball and sends sensory impulses through the optic nerve containing the sensory neurons (PNS) to the spinal cord.
- The spinal cord possess inter-neurons (CNS) that decides over the action to be done in response to the stimulus.
- The Response stimulus is send from the inter-neurons via the motor neurons (PNS) to the eye muscles of Sarah and Sarah performs the action, that is, she blinks.

The nerve that receives information is called a sensory nerve if that is what you're asking.
