NASA’s Kepler mission found evidence of several potentially habitable exoplanets, raising the possibility that life may have evolved independently outside of our solar system. If NASA found a novel lifeform, we would expect it to use energy molecules based on similar principles as lifeforms on Earth. The organism would likely use molecules with bonds. It might use two separate molecules, one serving as a rapidly utilizable energy currency and another molecule serving as long-term energy storage

The organism would likely use molecules with Covalent bonds.  

Explanation:

A covalent bond is a chemical bond that is prevalent in most matter and facilitates the sharing of electron pairs between atoms. Molecular Bond is another word for a covalent bond.

Molecular bonds are a repository of potential energy. This type of energy is also referred to as Chemical Energy.

Covalent bonds may take the form of single, double, and triple bonds. In order to separate any pair of bonded atoms, energy is required. The more strong a covalent bond is, the higher the amount of energy that is required to break it.

Cheers!

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
