Answer 2
Answer:

Final answer:

The occurrences of unusual odors in the water is considered as qualitative data in Professor Tan's studies. This is because such observations describe a quality of the water, not a quantity or measurable characteristic.

Explanation:

Qualitative data refers to non-numerical information. While studying the quality of water near chemical plants, Professor Tan might record several types of data. However, among the options presented, any occurrences of unusual odors in the water would be classified as qualitative data.

Indeed, experiences of our five senses like smell, color, and taste can be considered qualitative because they describe the quality of something rather than a quantity. So, in the case of Professor Tan's studies, if he noticed a strange smell in the water and recorded this observation, that would be classified as qualitative data.

Cuckoo bird relationship with a warbler

Answers


Cuckoos are commonly known for brood parasitism, meaning that they lay their eggs in other birds' nests and leaving the unfortunate mother of that nest to care for the invader baby. Sometimes, the cuckoo would even remove the mother's eggs to ensure that the invader baby bird would get the most care and food.

So a cuckoo bird's relationship with a warbler would be that of parasitism. At the very least, it's harmful for the warbler.
