Answer:
First question - Green curve
Second question - Red curve
Explanation:
Answer:
a. The formula for finding the number of colonies in a given volume is,
CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution
The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,
CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.
Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.
b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.
Answer:
Option (c).
Explanation:
Correlation may be defined as the statistical relationship used to explain the relation between two things. Two types of correlation are positive correlation and negative correlation.
The college students with more money and new clothes will help to make new friends as money can be used for more party and fun. The wealthy students has direct relation with new friends as they have more money to spend and enjoy with new friends.
Thus, the correct answer is option (c).
Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
Answer:
Musculoskeletal disorders
Explanation:
In the case shown above, the existence of musculoskeletal disorders should be evaluated initially so that the most appropriate treatment to repair any of these disorders and prevent more serious problems such as changes in posture, body movement and the natural movement of people should be started quickly. joints of the patient's body, which can cause physical deficiencies and severe deformations.
