Displacement is usually the method that is used to measure the volume of a solid with an irregular shape
The type of ion channels responsible for the depolarization phase of an action potential are Na+ (sodium)
channels. Sodium ions flow inward through the sodium channels and cause an
increase in the concentration of positively charged ions in the cell; this in
turn, leads to depolarization.
Answer:
I think A. is the right answer.
Explanation:
I searched up on how to determine population size and here here are some things I found. ¨The number of individuals in a specific area¨, ¨The most obvious way to determine the size of a population is to count, one by one.¨, but one thing I´m kinda sure is right is this one. It´s determining population size. ¨Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies¨ But just see for yourself.
Answer is preserve
1<em>. Removing oxygen:</em> The removal of oxygen from food preserves the food by avoiding the oxidation of food that leads to spoilage.Cover the food or vegetable tightly in air tight container to avoid oxygen reaching the cut cells which will cause spoilage of food.The fruits and vegetables should immediately be boiled or cooked to prevent oxidation.
2. <em>Removing moisture: </em>The removal of excess water from vegetables and fruits helps in preservation of food. The bacterial growth that spoils the food grows in moist environment hence reducing the moisture content will preserve food.
<em>3. Killing spoilage organism: </em>The ultraviolet light and infrared light are used to kill the organisms causing spoilage of food. Flash technique is also used for preserving food from microorganism.
