Which of the following best describes the transfer of phosphates and the impact on the environment and human health? Phosphates decrease the growth of algae in surface water bodies, and an overpopulation of fish in surface water bodies occurs.

Detergents containing phosphates are carried from land to water by rain, contaminating drinking water and causing digestive problems in humans.

Leaky septic tanks transfer phosphates into the groundwater and are converted into nitrites in the human body, which are poisonous and could be fatal for infants.

Nitrates increase the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f

Which of the following is a difference between active transport and facilitated diffusion? view available hint(s)which of the following is a difference between active transport and facilitated diffusion? facilitated diffusion can move solutes against a concentration gradient, and active transport cannot. active transport involves transport proteins, and facilitated diffusion does not. facilitated diffusion involves transport proteins, and active transport does not. active transport requires the expenditure of cellular energy, and facilitated diffusion does not.

During the winter, this species of fox has white fur, but in the summer, it has brown fur. what environmental change may have lead to this fox's fur color? snow cover increase in sun's brightness volcanic eruption global warming
