The answers that apply;
Researchers found cosmic microwave background radiation, which is a heat imprint left over from the big bang.
A redshift of light emitted by stars and galaxies indicates the universe is expanding
A primordial form of helium gas was found by the Endeavor space shuttle
Big Bang theory is a theory that endeavors to explain the origin of the universe. It stipulates that the universe exploded from a singularity and continues to expand today

Hope it helps:)
Bees can get in and out, carrying pollen with them from flower to flower pollinating as they go. On the the other hand, Gymnosperms have to let their seeds somehow travel away and plant itself, or with the help of nature, they plant themselfs
But it is easier for those flowering plants to pollinate.

Answer:
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
When food is eaten it is digested by converting it into smaller particles. These smaller particles are than digest and gives the energy to our body. The energy which produced is just come from our food on this base we can say that mass neither created nor destroyed but it change one form to another, just like the form from food to energy.
Another example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Answer:
(1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
