The two correct answers are:

- It was very tiny.
- It was extremely hot.

Which describes nuclear fusion?(1 point) Responses starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms starts when two atoms slam together, causing the larger atom to split into two smaller atoms starts when two atoms slam together, causing the larger atom to split into two smaller atoms starts when two atoms slam together to form one, heavier atom starts when two atoms slam together to form one, heavier atom starts when a neutron slams into an atom, causing two atoms to form one, heavier atom

The correct response is: "starts when two atoms slam together to form one, heavier atom".

The correct response is: "starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms".

The two correct answers are:

1. It was very tiny.
2. It was extremely hot.

The evidence supporting the Big Bang theory assumes two correct answers about the universe when it began:

1. It was very tiny.
2. It was extremely hot.

To arrive at these assumptions, scientists have analyzed various lines of evidence, including the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements. These pieces of evidence collectively support the idea that the universe originated from a highly compressed and hot state, often referred to as a singularity.
