Answer 1

The functions in the given options are the number of species in each sample collected from Waimea Valley to analyze its microbiome and the number of samples associated with a specific species collected from Waimea Valley to analyze its microbiome.

Step-by-step explanation:

A function is a relationship where each input (or domain) value corresponds to exactly one output (or range) value. In the given options, the functions are:

1. The number of species in each sample collected from Waimea Valley to analyze its microbiome.
2. The number of samples associated with a specific species collected from Waimea Valley to analyze its microbiome.

These two options represent functions because there is a one-to-one correspondence between the inputs (samples or species) and the outputs (number of species or number of samples).
