The term voltage describes the:
-electrical potential difference between two points.
-likelihood that an electrochemical gradient will develop.
-process of molecules moving from an area of high concentration to low
concentration.
-way in which osmosis determines water movement.
Answer:
electrical potential difference between two points.
Explanation
Voltage refers to the electrical potential difference between two distinct points. It doesn’t describe the way in which osmosis determines water movement (osmotic pressure), nor does it describe the process of molecules moving from an area of high concentration to low concentration (diffusion), or the likelihood that an electrochemical gradient will develop.
The term voltage describes the electrical potential difference between two points. Option A is correct.
Voltage is a measure of the amount of energy that is available to move electrons from one point to another. It is measured in volts (V). The higher the voltage, the more energy is available to move electrons.
The electrical potential difference between two points is created by the difference in the number of electrons at those two points. If there are more electrons at one point than at another, there will be a voltage difference between the two points. This voltage difference will cause electrons to flow from the point with more electrons to the point with fewer electrons. Option A is correct.

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state
The sympathetic nervous system is responsible for the mouse's physiological state.
The nervous system divides into the central nervous system and peripheral nervous system.
In the central nervous system, we have the brain and the spinal cord.
The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:
The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.
-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.
In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes

1. Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
1) The purpose of mitosis is growth and repair of cells
Explanation:
Prophase:
-DNA condenses (supercoiled, chromatids are visible under light microscope);
-Nuclear membrane begins to disintegrate (by the end of prophase it is completely gone)
-Centrioles move to opposite ends of the cell
-Splinde fibers start to form from the centrioles and grow
Metaphase:
-Spindle fibers, departing from both poles, are attached to each centromere, on opposite sides
-The spindle fibers pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane
Anaphase:
-The spindle fibers shorten
-The centromeres of sister chromatids split
-Chromatids move apart, pulled by the spindle fibers
-Chromatids become chromosomes
-Half of the chromosomes move to one cell pole, half to the other
Telophase:
-The chromosomes reach the cell pole
-Nuclear membrane reforms
-Spindle fibers break down and disappear
-The chromosomes begin to uncoil, which makes them diffuse and less compact
Cytokinesis:
-The cell membrane pinches inward until the cell divides in two;
-There are two daughter cells with the same structures and number of chromosomes as the parent cell
-Chromosomes decondense

A cytoskeleton is:_______.
a. a structure that aids in the process of cell division.
b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.
Answer: e
Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

You are in charge of genetically engineering a new organism that will derive all of its ATP from sunlight by photosynthesis. Will you put the enzymes of the citric acid cycle in this organism
Answer:
Yes.
Explanation:
I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.

What does the QRS complex represents as??
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
