The answer is <span>A. A leather tannery. A tannery produces a sludge as a byproduct that is high in various toxic elements including chromium, a heavy metal that is highly toxic. Other pollutants produced include sodium, calcium, sulfur, magnesium, phosphate, copper, tin, lead, arsenic cadmium and zinc. Tannery effluent is an extremely toxic pollutant that could cause great harm if released into the environment, and for that reason, the tannery industry needs to be highly regulated and managed. </span>
Answer:
Reduced reabsorption of salts and nutrients from the proximal tubule.
Explanation:
The proximal convoluted tubules are the site for reabsorption of the largest amount of solute and water from the filtered fluid. It reabsorbs 65% of water, electrolytes such as Na+ and K+, almost 100% of the filtered glucose and amino acids and other electrolytes such as Ca2+, Mg2+, etc.
The simple cuboidal epithelial cells of the proximal convoluted tubule have a prominent brush border of microvilli on their apical surface. These microvilli serve to increase the surface area for reabsorption and secretion. Destruction of these microvilli would reduce the reabsorption of the above-mentioned salts and nutrients from proximal convoluted tubules.
Answer:
The Muscular and Skeletal systems work together to help the body move and keep a shape.
Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.
Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
