Pls help i’m like taking a test for this rn- Explain how the flow of energy from Earth's hot interior drives the formation of metamorphic rock?

Over many thousands of years, energy from the Sun moves the wind and water at the Earth's surface with enough force to break rocks apart into sand and other types of sediment. ... The crystals and texture of the rocks change as they turn into metamorphic rocks like marble or slate.

Explanation:

"do a testcross with a homozygous recessive plant."

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
