Answer:

In the case of genes, one change in one sequence in a nucleotide can lead to major changes in the entire being of a living being. For example, a difference in two nucleotides could cause a a genetic disease like cystic fibrosis. The number of ways nucleotides can be arranged and the number of nucleotides differ from one organize to the next. This alone could explain how large differences between organisms are produced.

Question 7: What might be some implications of Robert Hazen’s experiments
Angelina_Jolie [31]

Answer:

Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020) .

Explanation:

Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.

You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

Why "charge" reduces rate of diffusion in cell membrane
Over [174]

A difference in charge between two regions of fluid can affect the rate and direction of diffusion between them. For example, positively charged substances will tend to diffuse toward a region with an overall negative charge.
