Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

In response to high amounts of phosphate transport into the cell: a. PhoR is phosphorylated by the phosphate transporter protein Pst b. PhoR binds with PhoB to remove PhoB repression of phosphate regulon genes c. PhoR is exported out of the cell to scavenge phosphate molecules d. PhoU changes conformation to allow PhoR to autophosphorylate e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.
Some viruses can be crystallized and their structures analyzed. One such virus is yellow mottle virus, which infects beans. This virus has a single-stranded RNA genome containing about 6300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure?
A) replication rate
B) transcription rate
C) translation rate
D) formation of new transcription factors
The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.

Ash trees are being removed when they show signs of the ash borer, a parasite that affects only ash trees and kills them off. What best explains why the ash trees are being cut down? The ash borer is a density-independent limiting factor, and humans need to clear cut to control tree density. The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees. Ash trees are outcompeting other trees and are thus more affected by the ash borer. Changes in climate have decreased ash borer populations which indirectly increased the need for cutting down the trees.
Answer:
The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees.
Explanation:
Ash borer is a parasite that affects ash trees it is highly destructive and invasive. It affects it Native host causing serious damages. Infected plant is cut down to avoid its spread to other healthy plant this is because ash bored when not control can destroy a whole population of ash trees in it Native environment within the space of 10 years. Its population dependent and would keep increasing in population and become more destructive. Thus, to avoid its spread infected trees are treated cut down and cut down.

The pathogenesis of tuberculosis includes the entrance of mycobacteria into the lungs and the resulting of which of the following? (Select all that apply.) Calcification Ghon tubercles Formation of granulomas Activation of macrophages Antigen-antibody complexes
Answer:
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. A granuloma is a mass of immune cells that forms when the immune system tries to isolate foreign substances.Macrophages can be activated by a variety of stimuli during the immune response. The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response.Explanation:
Tuberculosis is a disease caused by Mycobacterium tuberculosis, a bacterium that almost always affects the lungs. When the active form of the disease is present, symptoms (cough, fever, night sweats, weight loss, etc.) can be mild for many months. If not treated properly, Tuberculosis can be fatal.
Macrophages are a type of white blood cell found in the blood and they are the first body's defense against foreign substances. So they are effector cells of the immune system, the main players in the innate immune response.
When M. Tuberculosis infects a person, it attacks this first-response immune cells in the lungs, the macrophages. When they recognize these pathogens, macrophages produce the cytokines IL-1 and TNF-α, which cause the inflammation itself by acting on the endothelial cells of the nearby blood vessels to allow the transendothelial migration of the leukocytes. The inflammation t is a non-specific response to environmental aggressions, and its purpose is the isolation and destruction of the damaging agent, as well as repairing the damaged tissue or organ.
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. These lesions are especially common in children and may retain viable bacteria, so they are sources of disease transmission and may also be associated with classic tuberculosis reactivation after several years of inactivity.A granuloma is a roughly spherical mass of immune cells that forms when the immune system tries to isolate foreign substances that it has been unable to eliminate. Therefore it is a special type of inflammation that can occur in a wide variety of diseases. Infections that are characterized by granulomas include tuberculosis, but also include for example leprosy, histoplasmosis, cryptococcosis, coccidioidomycosis, blastomycosis, and cat scratch disease.Macrophages are usually in a resting state, they can be activated by a variety of stimuli during the immune response. Antigen phagocytosis serves as an initial stimulus; however, macrophages and their activity can be increased by cytokines secreted by, or through contact with, helper T-lymphocytes. One of the most powerful macrophage activators is gamma interferon. They are also able to recognize molecular patterns associated with pathogens. M. tuberculosis is a pathogen that contains Pathogen-associated molecular patterns (PAMPS), which are small sequences of molecules that repeat in groups of pathogens. They are recognised by Pattern-recognition receptors (PRRs), which include the Toll-like receptor (TLRs) family or the NOD-like receptors (NLRs). Once the receptors found in the macrophages recognize these PAMPS, the macrophages are activated are ready to perform an immune response.The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response. The concept refers to the specific binding of an antibody to an antigen to inhibit or delay its toxicity. When the macrophage recognizes a pathogen, it phagocytes it and degrades it, and presents its peptides to a T cell. This can activate a cytotoxic response, causing apoptosis of infected cells. Or, the T cell may activate a B cell to produce antibodies. Antibodies are proteins whose function is to detect any foreign elements that may enter the body. They normally detect specific parts of these elements, for example, proteins from the surface of bacteria or viruses. When antibodies bind to these foreign proteins, they act as a marker, making it easier for them to be recognised and eliminated by the cells of the immune system.Which piece of evidence supports the theory of continental drift?

Together, the stages of cellular respiration break down one molecule of ___ to generate a total of ____ molecules of ATP. The remaining energy is released as __ .
Answer:
1) Glucose
2) 36
3) Heat
Explanation:
Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.
Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.
Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.
The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel.
