Describe: Imagine a rock on a beach and a rock on the side of a mountain. How
would the factors that control weathering be different for these two rocks?
Answer:
mountainside: temperature extremes have more influencebeach: wind and waves have more influenceExplanation:
It depends on what you mean by "factors that control weathering" and where the beach and mountain are located.
If we assume that the rock on the mountain is at a place that has seasonal snow, and the beach is in a temperate climate, then we can make these observations.
The rock on the mountainside will be "weathered" by freezing and thawing, and by plant growth (roots). These will tend to enlarge any cracks in the rock, breaking it apart. While the mountainside may be windy, that wind may not carry particles that would tend to erode the rock surface.
__
The rock on a beach will be most affected by wave and water action, tending to smooth any exposed surface. Freezing and thawing action is less common, due to the moderating influence of the water on the local weather. In some cases, plant growth may also be a factor. Wind may pick up beach sand, further tending to smooth any exposed surfaces.

Where is the blood filtered
Blood is primarily filtered in the kidneys. Kidneys contain nephrons, which filter waste and excess substances from the bloodstream, producing urine as a result. The liver also helps detoxify blood.
Blood is primarily filtered in the human body by the kidneys. The kidneys play a crucial role in maintaining the body's internal environment by filtering blood to remove waste products and excess substances. This filtration process is essential for regulating fluid balance, electrolytes, and blood pressure.
Inside the kidneys, there are numerous tiny filtering units called nephrons, each consisting of a glomerulus and a renal tubule. The glomerulus acts as a sieve, allowing small molecules like water, glucose, and waste products to pass through, while retaining larger molecules like blood cells and proteins. The filtrate, which is the filtered blood minus these waste products, then travels through the renal tubules, where essential substances like water, sodium, and other ions are reabsorbed into the bloodstream, and the remaining waste is concentrated and excreted as urine.
In addition to the kidneys, the liver also plays a role in filtering blood by removing toxins and metabolizing various substances. However, the primary site of blood filtration in the context of waste and excess substance removal is the kidneys.

Why is the osmolarity of the medullary fluid in the kidney greater than the osmolarity of the blood plasma?
Answer:
This is because the loop of Henle that is found in the kidney functions as a countercurrent multiplier and contributes solutes to the interstitial fluid. Urea is recycled from the collecting duct and is transported to the interstitial fluid.
Explanation:
Osmolarity can be defined as the determination of the quantity of the solute that present in a given quantity of water( 1 liter ). It is used to measure the concentration of solute.
Osmolarity of the medullary fluid in the kidney greater than the osmolarity of the blood plasma and this is because the loop of Henle that is found in the kidney uses energy to generate an osmotic gradient that enables it to reabsorb water from the tubular fluid and produce concentrated urine a process that is referred to as countercurrent multiplication and contributes solutes to the interstitial fluid. Urea is recycled from the collecting duct and is transported to the interstitial fluid.
Hence, osmolarity of the medullary fluid in the kidney is set at a high limit of as 1500 mOsm/L while that of plasma osmolarity is 280 to 295 mOsm/L and it must not exceed the upper limit of 310 mOsm/L.
Answer:This is because the loop of Henle that is found in the kidney functions as a countercurrent multiplier and contributes solutes to the hyper-tonic medullary interstitial fluid.
Explanation:
Osmolarity is the concentration of a solution expressed as the total number of solute particles per litre. In other words Osmolarity” refers to the concentration of dissolved particles of chemicals and minerals, particles such as sodium and other electrolytes in your serum. Higher osmolarity means more particles in your serum. Lower osmolality means that the particles are more diluted.
The loop of Henle that is found in the kidney which function as a countercurrent multiplier, contributes solutes to the hyper-tonic medullary interstitial fluid making the osmolarity of the medullary fluid in the kidney greater than the osmolarity of the blood plasma.

Which of the following classes of antibodies is most likely to be made by the oldest plasma cell in a population of B cells?
a. IgM
b. IgG
c. IgA
d. None of the listed responses is correct.
Answer:
c. IgA
Explanation:
Specialized white blood cells called B lymphocytes (or B cells) contain antibodies. The mature B cells, or plasma cells, secrete millions of antibodies into the lymphatic system and the bloodstream. The plasma cell antibodies have the exact same antigen-binding site and specificity as the precursors to their B cells. Five different types of antibodies are present in humans: IgA, IgM, IgG, IgD,IgE.
In the oldest plasma cell igA classes of antobodies are present because initially plasma cells secret IgM but it switch and forms IgG, as the plasm aget older ans switch of antibodies takes place for scond time they can make IgA or IgE.

The stimulation of b cells to divide and mature is provided by
Answer & explanation:
B cells or B lymphocytes are produced and divided initially in the yolk sac (structure that stores the calf, a substance responsible for the nutrition of an embryo), then in the liver and later in the bone marrow, where they remain in the form of lymphoid progenitor cells until their maturation .
B cells are responsible for ensuring humoral immunity, characterized by the immune response through the production of antibodies, in order to fight invading cells such as infections by viruses or bacteria.
The stimulation of b cells to divide and mature is provided by T helper cells.
B cells participate in humoral immunity, this is characterized by the production and release of antibodies in order to destroy the antigens for which they were created.
The antigens that induce the activation of B cells can be protein, polysaccharides, lipids, etc, according to what type of antigen they require the participation of T helper cells.
T helper cells have receptors for MHCII in their membrane and binding for costimulators, which when they interact with these, activate T helper cells.Once activated, these secrete cytokines to stimulate the proliferation and differentiation of B cells.Cytokines are not specific for each antigen, although they have been secreted by the activation of a specific T helper cell.Cytokines stimulate the proliferation and differentiation of B cells and they determine what type of immunoglobulin genes will be produced by the activation of B cells.Therefore, we can conclude that the stimulation of b cells to divide and mature is provided by T helper cells.

Emulsion of fatty acids is necessary to _____.
a. break the intramolecular bonds
b. expose hidden bacteria in the fatty bolus
c. increase the surface area available for hydrolysis by lipase
d. trigger secretion of pancreatic enzymes
e. pass these molecules through the stomach
Answer:
c. increase the surface area available for hydrolysis by lipase
Explanation:
Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.
In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.
Answer:
Option C
Explanation:
The emulsification of fats is necessary so as to allow to easy break down of large molecules of fats into smaller droplets increasing their surface are such that enzymes like lipases can act on them, digest them breaking them down into fatty acids and glycerol to be easily absorbed by the small intestine.

Which statement about bandages is true? a. An occlusive primary layer allows air to penetrate the wound. b. If a wound is exudative, a semiocclusive primary layer is indicated. c. The tertiary bandage layer contacts the wound surface (if a wound is present) and may be adherent or nonadherent and occlusive or semiocclusive. d. A dry-dry bandage has as its primary layer an adherent material soaked in saline.
b. If a wound is exudative, a semiocclusive primary layer is indicated.
Explanation:
The bandage is a material which is used to cover the wound or injury to provide support to the medical device used for dressing over the wound. A bandage often restricts the movement of the body part over which it is applied.
The primary layer of the bandage remains in contact with the body tissues. The semiocclusive primary layer is applied over the wound if the serous fluid oozes out of the wound and to restrict the flow of exudate. This is applied to keep the wound in the moist state.
Based on above description, b. is the correct option related to the bandage.
