The way in which cilia and flagella bend. Concept introduction: Cilia and flagella are specialized arrangements of microtubules. It helps in the movement of sperm, algae and sweeping mucus containing trapped debris. A flagellum has undulating movement andcilia have alternative power and recovery strokes. Microtubules are hollow tubes of 25nm diameter. It is made of tubulin protein. It is important for the maintenance of cell shape and motility. In both cilia and flagella, microtubules are arranged in “9+2” pattern. There are two microtubules at the center and nine microtubules at the periphery. At the periphery, microtubules are present in doublet. The microtubules of cilia and flagella are attached with basal body. Basal body has “9+0” pattern of arrangement. There are zero microtubules at the center and nine microtubules at the periphery.

Use the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pK₁ = 4.874) to calculate the quotient [A-]/[HA] at three different pH values. pH = 4.479 [A-] [HA] [A-] pH = 4.874 [HA] = pH = 5.220 [A-] = [HA]

In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16
