70-75% ethanol is the most common disinfectant/sterilizing-sanitizing agent used in a microbiology laboratory. Explain why 70-75% ethanol is more effective than 95-99% ethanol.
1. The following population, C, has no limits on food resources or space:
Population size = 600 Births = 150 Deaths = 25
A. Calculate the r for this population if it is experiencing exponential growth
B. How many individuals will be in the population at the start of the second generation?
How many individuals will be in the population at the start of the third generation?
Now consider population D, in which food resources are limited and it is experiencing a logistic growth pattern. Population size = 500 rmax= the same for the previous problem (Population C). Carrying Capacity = 1,000 A.
How many individuals would be in the population at the start of the second generation.
Calculate the number of individuals that would be in the population at the end of the third generation.
In Chapter 3, you learned about carbohydrates and the various classifications of this macromolecule. Carbohydrates are part of a basic diet yet many diet plans to lose weight recommend lower carbohydrate consumption.
For this discussion post, analyze your current diet. Is your diet high or low in carbohydrates? Is your diet rich in protein? What do you believe is an ideal diet for a healthy lifestyle?
Then compare. The visual and information from Healthy Eating Plate suggest a universal guide for creating healthy meals that are also more sustainable in the long term. How does this compare to your own diet? Do you consider this a reasonable dietary plan? Why or why not?
What are the short term effects of Ablation?
Q1: Why a person with O blood group can donate blood to a patient with AB blood group but the opposite is impossible. Explain.
Q2:How does your body regulate the increase in the level of blood sugar after having a meal rich in carbohydrates. Focus on the relevant transporters.
