2 multiple choice 20 points
which idea explains the emergence of new species from pre - existing ones?
photosynthesis
plate tectonics
gravity
evolution

Explanation:

• Question 1: Fossils are the remains or traces of ancient organisms. By studying the fossil record, scientists can see how different species have evolved and changed over long periods of time. For example, they can observe changes in body structures, behaviors, etc. of species. It has nothing to do with predicting the future of Earth's climate (which is more related to climate models and current climate data), understanding how plants produce energy (which is related to photosynthesis and plant biology at a cellular level), or determining the age of the universe (which is a topic in astronomy and cosmology).
• Question 2: Evolution is the process by which new species arise from pre - existing species over time through mechanisms such as natural selection, genetic drift, and mutation. Photosynthesis is the process by which plants convert light energy into chemical energy. Plate tectonics is the theory that explains the movement of the Earth's lithospheric plates. Gravity is a fundamental force that attracts objects with mass.

Answer:

1. How species have changed over time.
2. Evolution.
