Hey there,
Scientists ensure the validity by sharing results with others to make sure they get the same results. They also conduct the expiremnt more than once.
Hope I helped :)
The earths four hemispheres are east , west , north and south. the relationship is they all go in different directions.
The term microevolution represents a predictive theory of how species might change with time.
The term macroevolution assumes that nature can create whole new structures and organisms simply be the environmental constraint.
Evolutionary biology, genetics, aetiology, genetics they overlap with the closely related sciences of ecology.
Ecology seeks to explain the movement of materials and energy through living communities, successional development of ecosystem and processes, adaptation and interactions.
Organisms benefit from adaptations because in order for them to survive, they need to adapt to their surroundings. For example, if a shark didnt have fins or a tail, it wouldnt be able to swim and catch its prey.
Mass? bigger mass has more gravitational pull, like why Jupiter has almost 80 moons
