Mutation in the hemoglobin gene can cause sickle-cell anemia. The defective protein found in sickle-cell anemia causes red blood cells to “sickle”—become a misshapen C shape. These misshapen cells abnormally stick to each other and can become trapped by leukocytes (white blood cells) that are rolling or paused on the endothelial cells lining the vessel. This causes blockages of small blood vessels, causing severe pain and strokes called vaso-occlusive crisis. A new drug that binds and blocks selectin proteins is in phase III clinical trials to test for improvement in patients' symptoms. Why might this be an effective treatment for vaso-occlusive crisis?

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.

what are the two phases of the respiratory movement of man? Are they the same in a grasshopper or a fish?
The two phases of the respiratory movement of man is inspiration ( or inhalation) and expiration (or exhalation). The phases of the respiratory movement of men is the same in fish because they also inhale and exhale.
What is inspiration (inhalation ) ?
Inspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction.
What is expiration (exhalation)?
Expiration (exhalation) is the process of letting air out of the lungs during the breathing cycle.

What the consequences would be if the entire water surface was covered with water lilies
Answer: There can be a ton of damage done if water lilies overgrow.
Explanation:
Water lilies protect the organisms under the body of water and provide shade to the plants and organisms underneath. These are very important for organisms, as they also provide a place to rest. But if the entire water surface were to be covered with water lilies, this would be a major problem, because sunlight would have no way of reaching below the surface, and this would decrease oxygen levels for plants and organisms. Without air and sunlight, plants will start to die and organisms of the body of water will also start to die because of no air to breathe. Also, overgrowth of water lilies causes water stagnation and leads to excessive algae blooms. The stagnant water attracts insects like mosquitoes, cockroaches, termites, and more pests which can harm plants and organisms.

Arctic sea ice keeps the polar regions cool and helps moderate global climate. Sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface.
Explanation:
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.
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.

An unknown bacterium has been inoculated onto a Mannitol Salt Agar plate and incubated at 37 degrees C. After 48 hours, you observe the plate. What interpretations and conclusions can be made from this result
Explanation:
Halotolerant is the ability of the organism to grow at the higher concentration of salt than the required concentration for its growth.
As we know Mannitol salt is used as selective medium for isolation of pathogenic bacteria. The medium has mannitol salt, phenol red indicator, 7.5% sodium chloride. This high salt concentration inhibits the growth of most bacteria.
The interpretations and the conclusion regarding to the given situation should be explained below.
What is Halotolerant?It is the capability of the organism for growing at a higher concentration of salt as compared to the concentration with respect to the growth. Since Mannitol salt should be applied as the selective medium for isolation of pathogenic bacteria. The medium contained the mannitol salt, phenol red indicator, 7.5% sodium chloride.
