Change/transformed
Explanation:
Igneous rocks can be transformed or changed to form metamorphic rocks in the presence of elevated pressure and temperature.
Metamorphic rocks are also called changed rocks in which a rock protolith especially from igneous or sedimentary rocks is transformed.
- In igneous rocks, minerals are recrystallized to form new ones
- The metamorphic rocks contain minerals that typifies them.
- Some metamorphic rocks can be formed at elevated pressure alone with increasing burial.
- Some can from through contact metamorphism where high temperature is the determining re-crystallization factor.
- Most metamorphic rocks form under conditions of high temperature and pressure.
- Examples of metamorphic rocks are schist, gneiss, talc etc.

Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.
Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
Answer:
Bactericidal products eliminate bacteria while bacteriostatic products keep bacterial populations in check by inhibiting replication.
