Describe one way a strawberry plant can benefit from the ability to use either mitosis or meiosis for reproduction.

Meiosis in strawberries is the sexual reproduction- meaning it occurs along with fertilization/ pollination of flowers of opposite genders and resulting in the actual fruit.  In strawberry plants, the advantages of sexual reproduction largely involve the fruit it makes, as it allows for the population to spread further and faster if the fruit were to be consumed by an animal.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

i'd say that the moon rock is about 2.2 billion years old.
