Answer:
The king snakes will be attacked and eaten by predators.
Explanation:
Mimicry can be described as a situation whereby an organism have the ability to imitate or copy one or more traits or character of another organism.
This can be described as a form of camouflage that organism exhibit to avoid been killed by predators, or to deceive other organism, by pretending to be one its species in order to kill it.
In the case, the harmless king snakes was trying to present itself as a harmful snake by mimicking the venomous coral snakes. Therefore, when it found itself where the coral snake are not wanted, it will be killed, because , it will be seen as a coral snake due to the mimicry process.

Explanation:
The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. <em>This is known as depolarization.</em>
The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. <em>This is called repolarization. </em>
For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of <em>hyperpolarization</em> that occurs while the K+ channels are open.
I annexed an image that illustrates this action potential process.
<em>Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)</em>
<em>Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).</em>
I hope you find this information useful and interesting! Good luck!<em>

Answer:
d. Smoking
Explanation:
Nicotine is a chemical found in many plants such as tobacco. It is one of the 4000 chemicals that tobacco presents and the main component that acts in the brain.
This chemical is absorbed through the skin and lining of the mucosa of the nose and mouth, or in the lungs by prior inhalation. Nicotine can quickly reach the bloodstream and brain and reach maximum levels. The action of smoking cigarettes causes nicotine to reach the brain in just 10 seconds after inhalation. Although the acute effects dissipate in a few minutes, they cause the need to continue the intake of the substance (addiction)
