Answer:
The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.
Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.

Answer:
Response of the postsynaptic cell is dependent on the neurotransmitter release
Explanation:
Calcium (Ca2+) is essential for the propagation of the action potential since it is required for neurotransmitter release. When an action potential reaches the end of an axon, voltage-dependent Ca2+ channels open and Ca2+ ions bind to regulatory proteins, thereby initiating the release by exocytosis of neurotransmitters contained in the presynaptic vesicles at the synapse and modulating the transmission of a signal to another neuron (i.e. the postsynaptic site).
Answer:
B
Explanation:
the earth rotates on a tilt so the answer is b
The correct answer is silt. Silt had the lowest threshold velocity. Silt is actually a granular material that is made up of somewhere in between of sand and clay. Its mineral's origins are quartz and feldsbar.
