The disease cholera results from infection of the epithelial cells of the gut by the phage Vibrio cholerae. The phage-infected cells produce new proteins, cholera toxin A and cholera toxin B, that are secreted into the gut. Cholera toxin B assembles into multisubunit complexes in the membranes of gut eptitheial cells and permits the toxic cholera toxin A to enter these cells, causing an ion imbalance and massive, watery diarrhea which permits the phage to spread to a new host. The structural assembly of cholera toxin B into multisubunit complexes is an example of: a. primary structure
b. secondary structure
c. tertiary stucture
d. quaternary structure
e. All of the Above

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.

Aphids are tiny insects that feed on plants. ladybugs are to plants because they eat aphids. which type of organism are aphids in this scenario? co decomposers predators prey producers

Food contains a sugar called ( ), which is broken down in a process called cellular ( ). this process uses ( ) to break down food molecules and provide energy for cells. fill in the parentheses
