Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of a

n animal? Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? Sodium ions can move down their electrochemical gradient through the cotransporter whether or not glucose is present outside the cell. Glucose entering the cell down its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose. The cotransporter can also transport potassium ions. Sodium and glucose compete for the same binding site in the cotransporter.

The correct answer is: A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose.

The Sodium Glucose Linked Transporters (SGLT) require the energy to transport glucose (uphill glucose gradient). They use that energy from this downhill sodium ion gradient created by the ATPase pump.

The answer is A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose.

Sodium ions are necessary for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions. Physiologically, it exists as an ion in the body. Sodium is needed by animals, which maintain high concentrations in their blood and extracellular fluids, but the ion is not needed by plants.

lord [1]

The scientific method is a research method that involves the question and problem definition, hypothesis formulation, goals, defining variables, collecting data and analysis, discussion, and conclusion.

<h3>What are the steps of the scientific method?</h3>

There are different steps to follow in a scientific method

  • Previous knowledge about the study object.
  • Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.
  • Goal especification. The goal is what the investigator wants to know.
  • Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.
  • Experiment. Different variables influencing the proyect are considered. Data collection and analysis stages. This step involves testing the observations.
  • Results
  • Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.
  • Conclusions.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It must be objective. Usually, it is written in the present time.

It is a claim of how it works a relationship between two or more variables. There must be a logical relationship between the involved variables.

<h3>What are dependent and independent variables?</h3>

When conducting an experiment, we must always consider the involved variables.

  • Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results. This variable is not affected by any other one but influences or causes a reaction in other variables.

  • The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one. Its response might be either directly proportional or inversely proportional to the change in the independent variable.

In the exposed example,

1. <em>Circle and label the question that is going to be investigated</em>.

How can sea turtles orientate into the ocean after hatching, paddle thousands of miles across the North Atlantic, and find their way back years later to the same beach they were born?

2. <em>What is the hypothesis</em>?

Turtles use Earth's magnetic fields and waves to orientate themselves in the water and on the ground.

3. <em>What is the independent variable</em>?

The magnetic field orientation.

4. <em>What is the dependent variable</em>?

Direction in which the turtles swim.

5. <em>What are the constants</em>?

Large glass tank filled with water and total darkness.

6. <em>Describe the data and analysis</em>.

Data,

  • Under normal magnetic field, the turtles swam towards the notheast.
  • Under reversed magnetic field, the turtles swam toward the southwest.

Analysis,

Turtles follow magnetic north and east, even when the magnetic field orientation is reversed.

7. <em>What is the conclusion</em>?​

The hypothesis is accepted. Turtles use Earth's magnetic fields to orientate themselved moving between the magnetic north and east.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
klasskru [66]

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells etc. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

Revise this sentence by replacing all gerunds with infinitives.
vekshin1

Answer:

Please see below

Explanation:

I always tell people that I love to dance, to write and to paint.

The verb keep cannot take an infinitive afterwards so it is better to replace that expression  altogether with another one that means the same thing, but that can use an infinitive. The verb love can take either gerunds or infinitives afterwards with only a subtle variation in the meaning.
