Answer:

Given the nature of descriptive statistics, psychologists will use descriptive statistics to assemble data about their clients through their observations of clients' behavioral patterns. Then a sample of the data will be taken. The sample is summarized statistically, interpreted, and recorded. Psychological reports can be issued based on the observed statistical results.

Explanation:

Psychologists and other occupations use descriptive statistics to describe the basic features of the data in their studies or experiments. Descriptive statistics provide simple generalizable summaries about the observed sample and the calculated measures. Using simple graphics, they form the basis of quantitative data analysis.

What air pressure, humidity, clouds, and temperature called?

dexar [7]

Air pressure is the amount of pressure exerted by the air in a particular air mass. Humidity is a measure of the water content of the air mass. Clouds are tiny drops of water or ice that form in the atmosphere. Wind is a process of movement of air that occurs due to the uneven heating of the Earth's surface.

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1

natulia [17]

Answer:

hyperpolarization
depolarization
hyperpolarization
depolarization
hyperpolarization
depolarization
depolarization

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. This is known as depolarization.

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. This is called repolarization.

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of hyperpolarization that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

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)

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).

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