Answer:
The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".
Explanation:
A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
The three stages of Action Potential are:
1. depolarization- Na+ channels open up inside of the membrane and becomes more positive than the RMP.
2. repolarization- The Na+ channels inactivating and K+ channels opening AP spike stops rising to which the membrane returns to RMP.
3. hyperpolarization- A few of the <span>K+ channels remain open and the Na+ channels reset inside of membrane becomes more negative than RMP.
Hope this helps!

Answer:
Polymer
Explanation:
Monomers can be linked together to form a polymer
Explanation:
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules. On the other hand, unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature, according to registered dietitian Anne VanBeber, Ph.D, professor and chair of nutritional sciences at Texas Christian University.
