Expert Solution & Answer

Answer to Problem 1Q

Is blood agar selective or differential? Differential

Explanation of Solution

Blood agar is composed of defibrinated sheep blood, sodium chloride and nutrient agar. Based on the ability of the innoculated bacterium, to hemolyse the blood agar i.e. destruction of red blood cells and the kind of hemolysis occurred helps in identifying the bacterium. The three types of hemolysis are as follows,

Alpha-hemolysis- Only partial damage of the red blood cells happens. −Normal Streptococci
Beta-hemolysis-Complete hemolysis- Pathogenic Streptococci
Gamma hemolysis- No hemolysis.-Normal Streptococci

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.

Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
