Answer:
(b) Voltage gated
Explanation:
The cell membrane acts as a barrier that separates two aqueous media of different composition, the extracellular and the intracellular, regulating its composition. Most of the liposoluble drugs and solutes, when not ionized, directly cross the cell membrane through a passive diffusion process, which facilitates the passage of the medium where it is more concentrated to the one that is more diluted. The difference in concentration between the two media is called the concentration gradient, and diffusion will continue until this gradient is eliminated. According to Fick's law, the speed of this process will be much faster the higher the concentration gradient and the liposolubility of the molecule and the smaller its size.
More hydrophilic molecules, such as ions, are immiscible in membrane lipids and pass through specific specific transport mechanisms. In some cases, ions pass through hydrophilic pores called ion channels, and in others a favor of their concentration gradient is transported by binding to the transporter or transporter proteins. Both transport systems are passive and therefore do not consume energy. The great advantage is that the ion channels allow the flow of ions through a much higher speed than that of any other biological system. The flow of ions through each channel can be measured as an electric current, which is capable of producing rapid changes in membrane potential.

The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
Answer:
well theory is ranked second highest in certainty in scientific nomenclature. theory dictates it is more certain of a principle than a hypothesis yet not concrete enough to be a law. examples are the theory of evolution versus the law of gravity
Given what we know about the correlation between the liver temperature of a corpse and the estimated TOD, we can conclude that the estimated time of death is approximately 10:30 pm of the night before.
<h3>How do we estimate the TOD?</h3>
- This can be achieved using a mathematical formula.
- The formula in question involves taking the normal body temperature of a living human and subtracting the liver temperature of the body.
- The remaining is the difference in temperature.
- Given that a body will lose roughly 1.5 degrees worth of heat per hour, we divide the remaining number by this to get the amount of hours since the death.
- This leads us to the conclusion that this individual perished roughly 15.5 hours earlier.
Therefore, given the way in which we use the correlation between liver temperature and time to analyze and approximate a time of death, we can confirm that this individual will have perished at roughly 10:30 pm of the night before.
