Which of the following is not a type of adaptation?
enyata [817]

Answer: The correct answer for the first question is- B) Mechanical.

Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.

Mechanical is not a type of adaptation as it deals with movement of objects.

The correct answer for second question is- C) Variations.

Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).

Thus, difference is in the feather color reflects variations.

When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!
