Answer:
Voltage-gated membrane channels open, and Ca+2 enters the cytoplasm, increasing intracellular calcium
Explanation:
The neurotransmitters in the neurons are stored in the synaptic vesicles in the synaptic knob present at the axon terminal.
The neurotransmitters are released when the action potential reaches the axon terminal and opens up the voltage-gated calcium channels. The calcium channels allow the entry of the calcium from the synapses and this causes the release of the synaptic vesicles which fuses with the cell membrane. This fusion releases the neurotransmitter in the synapse.
Answer:a
Explanation:the type of plant doesn’t matter because if the soil water and sun are good it will grow
Islands are separated from other landmasses, so the organisms on an island will evolve separately from organisms on the mainland.
Layers of the skin affected by the burn in this question are the epidermis and dermis. When a burn occurs to soft-tissue, the fragile, yet strong nerve endings enter in a "protective and chaotic" mode, trying to restore a homeostatic environment. There is also a massive attempt from the body to thermoregulate itself. The heat from the burn is causing the body to release excessive heat to prevent itself from over-heating. Until the brain is signaled to slow this process, heat will rapidly exit the body, thus the difficulty keeping warm
Genetical experiments suggest that traits acquired during a person's lifetime are not inherited as proposed by Lamarck's theory that traits acquired or changed over an individual's lifetime could be passed on to its offspring. Through experiments, scientists through many observations and real examples that changes that often occur in an animal's life are not passed down to it's offspring.
