Answer:

Independent variable is that which we change or manipulate.

Explanation:

By changing the independent variable, there is a corresponding change in the dependant variable which we intend to measure.

Answer:

The dependant variable is the one you measure. The dependant variable depends on how you change the independent variable.

Explanation: For example we want to observe speed of a car change with respect to time.

Here, time is the independent variable as it has its own pace regardless of the car. However, at different instances of time , the car has different speeds. Thus, the speed of the car is the dependant variable as it depends on time.

The evolutionary theory that suggests that a species can suddenly and rapidly evolve into a new species is ?

Mekhanik [1.2K]

Punctuated Equilibrium/ Equilibria proposes that once species appear in the fossil record, the population will be in the state of little or absent morphologic change. This is called a state of stasis. The theory further proposes that the population is confined to infrequent and geographical rapid events when significant evolutionary change happens. The parent species will the split into two distinct species. This process if called cladogenesis.
