Microvilli are filamentous structures on the surface of intestinal cells. Their formation depends on microfilaments. What would happen to intestinal cells when microfilaments’ formation is blocked by cytochalasin, a chemical that inhibits actin polymerization? Surface area decreases; cell volume decreases; efficiency of nutrient uptake increases. Surface area does not change; cell volume decreases; efficiency of nutrient uptake increases. Surface area decreases; cell volume decreases; efficiency of nutrient uptake does not change. Surface area decreases; cell volume does not change; efficiency of nutrient uptake decreases.

Photosynthesis converts solar energy into what type of energy?

Dr. kaylan is an ecologist who studies bird behavior. she sets up an experiment to test which type of food crows are most likely to eat when given a choice between walnuts, corn, and sunflower seeds. to perform her experiment, dr. kaylan places three food bins in an area frequented by cows. each bin contains one of the three food types. then, she measures how much of each food type is eaten every day for a month and summarizes the results of her experiment in the pie chart below. based on her results, dr. kaylan concludes that crows choose to eat corn more frequently than other food sources because it has a higher nutritional value. what is a reasonable alternate conclusion that can be drawn from dr. kaylan's data
