Television commercials often tell us about the benefits of active yogurt cultures, or specific living bacteria, to our digestive system and overall health. two bacteria cultures, lactobacillus bulgaricus and streptococcus thermophilus, convert pasteurized milk to yogurt by fermentation. all yogurts are required to be made with these two cultures. in addition, some yogurts contain lactobacillus acidophilus, bifidu. some health food advocates claim that some yogurts may have no active cultures. if the label says "made with active cultures," are we always getting the benefits of active bacterial cultures?

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.

All but one describes an effect of aging on the digestive system. a) decreased acid secretion b) decreased elasticity of stomach c) capacity to resist damage decreases d) food remains in stomach for less time
