Answer 1

The two characteristics of life described in the statement are:

1) Growth and development: The statement highlights the growth and development of a human being from a single cell to an adult made up of trillions of cells. This characteristic of life involves an increase in size, complexity, and organization.

2) Multicellularity: The statement also mentions that an adult human is made up of trillions of cells. This reflects the characteristic of multicellularity, where an organism is composed of multiple specialized cells working together to form tissues, organs, and systems.
