Question

1. how do all organisms begin life?

Explanation:

In the context of biology (a subfield of Natural Science), all organisms begin life as a single cell. For example, in sexual reproduction, a zygote (a single cell formed by the fusion of sperm and egg) is the starting point, and in asexual reproduction, organisms also start from a single - celled structure like a spore or a budding cell. This is a fundamental concept in the study of the life cycle of organisms.

Answer:

All organisms begin life as a single cell (e.g., a zygote in sexual reproduction or a single - celled structure in asexual reproduction).
