Answer:
<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>
Explanation:
- As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.
- Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
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:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
