You are studying ion channels and have set up model lipid vesicles containing the three following transporters:
1. a Na+ /H+ antiporter driven by the Na+ concentration gradient.
2. The common 3Na+ /2K+ pump.
3. K+ leak channels. The experiments are designed such that all three transporters are oriented in the model lipid bilayers in the same direction they would be in the plasma membrane of a cell and that concentration gradients in vitro mimic the concentration gradients experienced by cells (e.g., the extracellular Na+ concentration is similar to the concentration outside of the vesicle whereas the concentration in the lumen of the model vesicles is similar to intracellular Na+ levels).
Required:
a. Draw the arrangement and ion flow of the three types of transporters in the model membranes.
b. What do you predict will happen to the pH of the vesicle lumen if you treat the model membranes with the drug oubain that impairs function of the 3Na+/2K+ pump? Briefly explain your answer in terms of what happens with each transporter.
Answers
Answer and Explanation:
a) you will find the arrangement and ion flow of the three types of transporters in the model membranes in the attached files.
K+ leak channels are channel proteins that allow K⁺ to leave the cell in favor of its concentration gradient. It keeps a stable equilibrium by taking out K⁺ that the 3Na+ /2K+ pump brings into the cell. Any alteration in the pump leads to an alteration in the leak channel functioning. Na+ /H+ antiporter is an integral membrane protein, and a secondary transporter is responsible for the interchange of H+ and Na+ through the membrane with no use of energy. It regulates pH within the cell. It responds to the Na+ and H+ concentration gradient, determined by the 3Na+ /2K+ pump. An alteration in the pump functioning produces a change in the Na gradient and consequently affects the antiporter interchange action. 3Na+ /2K+ pump is an integral protein that transports K+ and Na+ against the electrochemical gradient. A significant amount of energy is used to make the pump function. It brings K+ into the cell and takes Na+ out of it. It keeps the membrane potential and the electrochemical gradient constant. The pump function is associated with the leak channels and the antiporters function.Under normal conditions, the cell interior has a lower pH than the exterior. The K+ concentration is higher in the interior, while the Na+ concentration is higher in the cell exterior. The interior of the cell is always more electronegative than the cell exterior.
b)
The drug ouabain inhibits the pump. It impedes the Na+ exit and the K+ entrance. It occurs a sharp increase in the Na+ intracellular concentration, which influences the Na+ /H+ antiporter that changes the ions´ direction, taking out Na+ and bringing in H+ to compensate the intracellular Na+ excess. There is also a decrease in the leak channel function, which does not allow K+ to leave the cell.
Whenever the pump is inhibited, there is an increase in the intracellular pH, because Na+ concentration increases in the interior.

While it is not possible to actually travel through all of the layers of Earth, in what order would the adventurer have traveled to reach the center? Write the layers (outer core, mantle, inner core, crust) in the correct order from outermost to innermost layer.
Answers
Answer:
The correct answer would be - crust, mantle, outermost and innermost layer.
Explanation:
It is not possible to travel through all of the layers of Earth, however, Hypothetically, if an individual takes a journey of traveling to the core of the Earth, he needs to go through total five total layers, including the "center of the Earth" as described in Jules Verne's novel.
The crust is the first and outermost layer of the earth from the top of the earth's surface. It is the layer we and all geographical areas such as caves present. The second layer is the mantle that can be distinguished in the upper mantle is the primary mantle itself. After the mantle person would enter the outer core and then the final layer is the inner core.

Explanation:
Petrus brings his 87-year old grandmother to the emergency department where you work. His grandmother has a fever, is dehydrated and confused, and complains of pain when urinating. Petrus reports that she has not been eating or drinking, but she has no signs or symptoms of gastrointestinal distress. You request blood samples and also a urine sample. You decide to keep Petrus' grandmother in the hospital so that she can be given intravenous fluids. You also want to wait for the lab test results before you decide whether she required additional treatment or if she can return home.
1. When Petrus' grandmother's test results are sent to you, you discover that while her blood work is normal, her urine has Gram-negative bacilli in it. Based on this, you know that the cells are:______.
a) stained blue and are cylindrical in shape.
b) stained purple and are cylindrical in shape.
c) stained pink and are spherical in shape.
d) stained pink and are cylindrical in shape.
e) stained green and are oval in shape.
2. Petrus asks you what the Gram-negative result means and you explain that the bacteria causing his grandmother's UTI:____.
a) have a thin cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
c) have no cell wall but they have a thick outer membrane which makes the cells less sensitive to the antibiotic penicillin.
d) have a thin cell wall and an inner cell membrane which makes the cells less sensitive to penicillin.
e) have no cell wall which makes the cells more sensitive to the antibiotic penicillin.

d) stained pink and are cylindrical in shape.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.

A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
Sample proportion = 38/50

The black panther phenotype in jaguars, which is a completely black coat, is thought to be determined by a single gene. If the presence of this phenotype were unrelated to habitat type, but was found to be much more common in populations in Costa Rica relative to populations in Brazil, what would be the most likely explanation for this geographic pattern
Answers
Answer:
Due to suitable climate and food availability.
Explanation:
The reason for this geographical distribution is the availability of suitable climate and food. Black panthers live in the hot, dense tropical rainforests environment where there is a lot of food present that is necessary for sustaining the population of black panthers. Black panthers are more common in Costa Rica as compared to populations in Brazil due to climate as well as food availability.

What are vascular plants?Vascular plants are a group of plants that have specialized tissues for conducting water, minerals, and nutrients throughout the plant. These specialized tissues, called vascular tissue, consist of xylem and phloem.
Xylem is a type of vascular tissue that is responsible for transporting water and minerals from the roots to the rest of the plant. It consists of tubes made of dead cells with thick cell walls that form a continuous network throughout the plant.
Phloem is another type of vascular tissue that is responsible for transporting sugars and other nutrients throughout the plant. It consists of tubes made of living cells that are arranged in a circular pattern around the xylem.
Vascular plants are important because they are able to grow to larger sizes than non-vascular plants due to their ability to transport water and nutrients throughout the plant. Examples of vascular plants include trees, grasses, and flowers.
