Question 1

Adaptations

Answer 1

Answer 2

refers to any alteration in the physical, chemical, or biological components of an organisms surroundings

Question 3

Variation

Answer 3

refers to the differences observed between individual organisms within a species, which can be cause by genetic factors or environmental influences on gene expressions and can manifest in physical appearance, behavior, or other characteristics.
