Answer - <span>C) Trees and shrubs provide shade, which keeps the water temperature cooler. Lower temperatures allow the water to hold more oxygen, which in turn creates a healthier habitat for the trout.</span>
Reasoning - The back story is if the water temperature is being changed. It will affect the trout indirectly warming the water. In turn if you have shades and shrubs to provide it for cooler areas it will preserve O2 a Certain Habitat for the Species.
Answer:
The polarity of membrane phospholipids
Explanation:
The inner core of membranes is made of nonpolar tails of phospholipids which in turn makes the membranes impermeable for polar, large and charged substances since these substances cannot cross the non-polar inner core. The saturated hydrocarbon tails pack tightly and make membrane less permeable while cholesterol affects the membrane permeability by interacting with non-polar tails.
Higher temperatures make the membrane more fluid and more permeable while at lower temperatures, membranes are more rigid due to tight packing of hydrocarbon tails and less permeable. The polar heads of phospholipids make the inner and outer surface of the membrane. Therefore, the polarity of phospholipids does not affect the membrane permeability.
All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers "nucleotides." The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA.
