The average of the following set of measurements is 20°C.
To find the average of the given set of measurements
Given:
Set of measurements = 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C
Number of Observations = 7
Average = Sum of observations/Total number of observations
Sum of observations = 27°C+12°C+31°C+19°C+23°C+11°C+17°C
= 140
Total number of observations = 7
Substitute the values in the formula
= 140/7 = 20°C
Therefore, the average of the following set of measurements is 20°C

Answer:
The correct answer is C. co-evolution
Explanation:
When two or more species evolution is influenced by each other and are interdependent than this type of evolution is known as co-evolution. There are several examples of co-evolution like predator-prey co-evolution, flowering plants and pollinators evolution, etc.
The predator-prey evolution is famous in which there is selective pressure on prey to evolve to avoid getting hunted and the same pressure is on predator to evolve with prey so that they can get their food and survive. Therefore the correct answer is co-evolution.
Answer:
The distribution of chloroplasts in each algae cell was approximately the same.
The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.
Explanation:
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
