Which statement describes how a scientist makes scientific explanations?

A)

In science, every scientific explanation is actually based on empirical evidence, which consists of logical information that are obtained through observation, measurement, and experimentation.

A scientist bases scientific explanations on a large body of observations of the natural world.

Explanation: Hope this helps :)

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
