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:
I expect that there will be a small number of male turtles and a large amounts of female turtles. If there are small amounts of male sea turtles, then reproduction of these turtles will be difficult and maybe a threat to their species.

Answer:
Explanation:
The primates have a hand feature which increases their fitness in the tree environment are the opposable thumbs. The thumbs are the broadest digit of the hand. The thumb can move in different directions in comparison to the other digits of the hand. This is an advantage in primates to hold and grasp the objects with their hands.
The monkeys climbing on the trees grasp the branches of trees to move from one tree to another.
Answer:
The answer is C Protista.
