Answer:
C) zooxanthellae does not need coral to survive
Answer:
lateral inhibition in the retina
Explanation:
Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.
Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.
Life has the following major characteristics that define it;
- It responds to stimuli
- It reproduces
- It exhibits growth and development
- It has some order – has levels of organization
- They regulate their internal environment through homeostasis
These characteristics distinguish the living thing from non-living things.
