Answer:
Over millenia, these rocks get pushed back into the Earth's mantle, and get pushed into a volcano heating it up and turning it into magma.
Explanation:
Magma is molten rock, meaning existing rocks must be getting melted, the way the melting happens is by the rocks getting pushed into the ground by landforms and penetrating the mantle, this is how the cycle starts all over again.

Answer:
No and Yes
Explanation:
Protists are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.
If they're in the kingdom Protista, then yes, they are protists. If not, then they aren't!
Answer:
complementation test
Explanation:
The easiest examination to differentiate between the two possibilities is the complementation test. The test is simple to perform: two mutants cross and F1 is analyzed. If F1 expresses the wild-type phenotype, we conclude that each mutation is in one of two possible genes necessary for the wild-type phenotype. When it is shown that it is genetically shown that two (or more) genes control a phenotype, the genes are said to form a complementation group. Otherwise, if F1 does not express the wild type phenotype, but rather a mutant phenotype, we conclude that both mutations occur in the same gene.
These two results can be explained considering the importance of genes for phenotypic function. If two separate genes are involved, each mutant will have an injury to one gene while maintaining a wild-type copy of the second gene. When F1 occurs, it will express the mutant allele of gene A and the wild-type allele of gene B (each contributed by one of the mutant parents). F1 will also express the wild type allele for gene A and the mutant allele for gene B (contributed by the other mutant parent). Because F1 is expressing the two necessary wild-type alleles, the wild-type phenotype is observed.
Answer:
There are two main ideas about how chromosomes move in anaphase A. One is that motor proteins at the kinetochores use the energy of ATP hydrolysis to pull the chromosomes along the kinetochore microtubules, which depolymerize as a consequence.
