This is due to the fact that ________.A) the voltage gated potassium ion channels remain open long enough to hyperpolarize the axon membraneB) the membrane is now impermeable to all ionsC) the sodium potassium pump will stop working during relative refractoryD) the inactivation gates on voltage gated sodium ion channels are closed

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

BIOLOGY > HUMAN BIOLOGY > DIGESTIVE SYSTEM

EXPLANATION:

In the mouth, physical digestion of the food happens by chewing of the food. In the stomach, the food is broken down by chemical digestion into smaller particles that can be easily absorbed by the body. It will pass through the small intestine first where the microvilli and villi are. Then, most of the undigested and unabsorbed food particles are passed through the large intestine. It will be getting secreted out of the body after.

ANSWER: D. Duodenum is the first section of the small intestine right after the pyloric sphincter.

Answer:

Explanation:

From the information given:

The cell potential on mars E = + 100 mV

By using Goldman's equation:

\(E_m = \dfrac{RT}{zF}In \Big (\dfrac{P_K[K^+]_{out}+P_{Na}[Na^+]_{out}+P_{Cl}[Cl^-]_{out} }{P_K[K^+]_{in}+P_{Na}[Na^+]_{in}+ P_{Cl}[Cl^-]_{in}} \Big )\)

Let's take a look at the impermeable cell with respect to two species;

and the two species be Na⁺ and Cl⁻

\(E_m = \dfrac{RT}{zF} In \dfrac{[K^+]_{out}}{[K^+]_{in}}\)

where;

z = ionic charge on the species = + 1

F = faraday constant

∴

\(100 \times 10^{-3} = \Big (\dfrac{8.314 \times 298}{1\times 96485} \Big) \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)\)

\(100 \times 10^{-3} = 0.0257 \Big ( \dfrac{4}{[K^+]_{in}} \Big)\)

\(3.981= \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)\)

\(exp ( 3.981) = \dfrac{4}{[K^+]_{in}} \\ \\ 53.57 = \dfrac{4}{[K^+]_{in}}\)

\([K^+]_{in} = \dfrac{4}{53.57}\)

\([K^+]_{in} = 0.0476\)

For [Cl⁻]:

\(100 \times 10^{-3} = -0.0257 \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)\)

\(-3.981 = \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)\)

\(0.01867 = \dfrac{120}{[Cl^-]_{in}}\)

\([Cl^-]_{in} = \dfrac{120}{0.01867}\)

\([Cl^-]_{in} =6427.4\)

For [Na⁺]:

\(100 \times 10^{-3} = 0.0257 \Big ( \dfrac{145}{[Na^+]_{in}} \Big)\)

\(53.57= \Big ( \dfrac{145}{[Na^+]_{in}} \Big)\)

\([Na^+]_{in}= 2.70\)

Stem cells are a type of unspecialized cell with the potential to develop into many different types of specialized cells. They are found in all multi-cellular organisms, including humans, and are characterized by their ability to divide and differentiate into a wide variety of cell types. Stem cells are important for the development and maintenance of organisms, as they can replace damaged or lost cells, and can be used to study the development of humans and other organisms.

This is the life cycle of an apple tree. An apple tree starts as a seed planted in the ground. The seed sprouts and grows roots, a stem and leaves.

1. Develop a hypothesis: Sienna hypothesized that plants move toward light. 2. Set up the experiment: Sienna placed one plant near a window and another in a dark room with a small opening that allowed light to come through. 3. Observe and record: Sienna checked the plants every few days and recorded the direction of their growth. 4. Analyze the data: Sienna examined the recorded data to determine the direction of growth for each plant over the six-week period. 5. Draw conclusions: Based on the data analysis, Sienna drew conclusions about whether the plants moved toward the available light source or not.

1. Sienna developed a hypothesis that plants move toward light. This is the initial step where she formulates her prediction based on prior knowledge or observations.

2. Sienna set up the experiment by placing one plant near a window and another in a dark room with a small opening that allowed light to come through. This step ensures that there are two distinct conditions to compare the plant growth.

3. Every few days, Sienna checked the plants and recorded the direction of their growth. This step involves making regular observations and documenting the changes in plant growth over time.

4. After six weeks, Sienna gathered all the recorded data, which included the direction of growth for each plant. This data would serve as the basis for further analysis.

5. Sienna analyzed the data by examining the recorded observations. She compared the direction of growth for each plant and looked for patterns or differences between the plant near the window and the one in the dark room.

6. Based on the data analysis, Sienna drew conclusions about whether the plants moved toward the available light source or not. This step involved interpreting the data and determining if the hypothesis was supported or refuted by the evidence gathered from the experiment.

By following this sequence of steps, Sienna was able to study movement in plants and draw conclusions about their response to light.

b)eutrophication

Explanation:

have you ever seen a lake or body of water with a layer of green on top? That's eutrophication due to heavy amounts of growth nutrients (primarily from runoffs from agriculture) in water. Simple plants utilize those and grow very fast. As they grow, they take up the oxygen and make water oxygen poor. These produce deadzones cuz the water life basically suffocates to death due to less oxygen. Eventually plants will also die

Fnet=5N. When a force is applied to the body, not only is the applied force ,there are many other forces like  Fg, Ff and the normal force that balances the other force.

Therefore, the net force formula is ,

F net = Fa + Fg + Ff + FN.

Where,

Fa is applied force,

Fg is the gravitational force,

Ff is the frictional force,

FN is a normal force.

Force FN= 3N

Force Fg = 3 N

Force Ff = 5N

The net force formula is given by

FNet = FN-Fg + Ff

FNet  = 3-3+5

FNet  = 5N

Therefore, the net force is 5N.

Ff=kFN F f = k F N, where k is the coefficient of kinetic friction and FN is the object's normal force, is the formula for kinetic friction.

The net force is what remains when two forces acting on an item in opposite directions don't exactly cancel out (the difference in the forces). The net force is the sum of the forces acting on an object when two or more forces are acting on it in the same direction.
