After one week of life, the weights of five chick the same sex hatched simultaneously from eggs of the same hen and fed on same diet were 45g, 40g, 35g. 33g and 30g. This is an example of
- A) growth rate
- B) selection
- C) variation
- D) mutation
Correct Answer: A) growth rate
Explanation
The question is asking about the weights of five chicks of the same sex that hatched at the same time from eggs of the same hen and were fed the same diet. After one week of life, their weights were recorded as 45g, 40g, 35g, 33g, and 30g. The question wants us to identify what this is an example of. The correct answer to this question is option C: variation. This is because the weights of the five chicks varied despite being of the same sex, hatched from the same hen, and fed the same diet. Variation is the differences that exist between individuals of the same species. This variation can be caused by genetic factors, environmental factors or a combination of both. In this case, the variation in weight could be due to genetic differences between the chicks or due to differences in the way they responded to the environment, or a combination of both. It is important to note that variation is a natural occurrence in living organisms and is essential for evolution to occur.
