In his theory, lamarck suggested that organisms will develop and pass on to offspring variations that they need in order to survive in a particular environment. in a later theory, darwin proposed that changing environmental conditions favor certain variations that promote the survival of organisms. which statement is best illustrated by this information? (a) scientific theories that have been changed are the only ones supported by scientists. (b) all scientific theories are subject to change and improvement. (c) most scientific theories are the outcome of a single hypothesis. (d) scientific theories are not subject to change.

The correct answer would be (b) All scientific theories are subject to change and improvement.

Explanation:

No theory is considered the absolute truth, although some have been proved and deeply studied, through years many theories that were considered completely true, have become incomplete or false. Therefore, as true and correct a theory sounds, it can still be proved wrong in the future.

yes it is weird but true

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
