Answer:
Question 1
vacuole
Question 2
ribosomes
Explanation:
Prokaryotes are so important to life on Earth as they play a critical role in recycling of nutrients by decomposing dead organisms and allowing their nutrients to be re-used.
Prokaryotes are single celled microscopic entities. They neither have specialized organelles nor a prominent nucleus with membrane. examples are cyanobacteria, E.coli.

Prokaryotes is important to life on earth because they remove carbon dioxide (carbon cycle) and return it to the atmosphere. It is also a vital part of the nitrogen cycle. Basically, in simple terms if we didn't have them then we wouldn't be able to thrive and survive.
B. There will be a 1:1 ratio of mutant to wild-type.
C. All of the F1 progeny would be wild-type.
D. All of the F1 progeny would display a novel mutant phenotype that differs from that of the parents.
The answer is not C.
Answer:
All of the F1 progeny would be wild-type.
If the two mutations are in different genes, then we expect complementation to occur (each mutant strain provides a functional copy of the gene that is defective in the other strain) and wild-type progeny to be produced
In genetic complementation testing, a 1:1 ratio of mutant to wild-type phenotypes is expected in the progeny when the two mutations are in the same gene.
In genetic complementation testing, crosses are performed between pure-breeding strains for recessive mutations that confer the same mutant phenotype. If the two mutations are in the same gene, then the expected phenotypic ratio among the progeny is a 1:1 ratio of mutant to wild-type, which means equal numbers of individuals displaying the mutant phenotype and individuals displaying the wild-type phenotype.
