Answer:
Batesian mimicry
Explanation:
Batesian mimicry refers to a form of biological resemblance by which a harmless prey species evolved in order to imitate another harmful species for a common predator, thereby increasing its chances of survival. This defensive behavior was described by Henry W. Bates, who made ecological observations of butterflies in the Brazilian rainforest. Thus, an innocuous species that show harmful signals against a predator will gain protection against this predator. Batesian mimicry is a type of mimicry that benefits from the predator's learned avoidance behavior.
1. Americans are more racially and ethnically diverse than in the past, and the u.s. is projected to be even more diverse in the coming decades.

Answer:
A) Biochemical test
Explanation:
The complete question is as follows:
You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles appear, indicating the presence of a particular enzyme that the bacterium produces. What type of identification test does this exemplify?
A) Biochemical test
B) Immunochromatography
C) Microarray
D) Precipitation test
- Biochemical testing is a useful method using which one can identify the bacteria upto the genus and species level.
- Each organism identified through biochemical testing has its specific biochemical reaction that acts as a fingerprint for its identification.
- The reason why different biochemical reactions are produced by different bacterial species is because the different species possess their own set of DNA that encodes for unique set of proteins in each of them.
- Therefore, the production of bubbles on addition of hydrogen peroxide in an inoculum of bacterium due to presence of a particular enzyme unique to the bacterium is a type of biochemical identification test.
Answer:
if a method is repeatable it could help solve other questions
The question is not complete but it can be answered in general as the plants cannot survive in acidic conditions.
Answer: High acidity is harmful to this type of plant.
Explanation:
The plants that were kept in the higher acidic conditions are less likely to grow in higher acidic conditions.
The plants that were kept in more basic conditions will also not grow properly as the pH of the soil should be neutral, slightly acidic or slightly basic.
The plants that was kept as a control on the pH of 7 will grow the best as the pH is optimum for the growth of the plants.
The conclusion is high acidity is harmful for the life of the plants.
