Answer:
changes in the environment and or cross breeding
Explanation:
Answer: B) Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.
HEYYY!! Hope this helps! :D
Answer:
A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.
Explanation:
Answer;
-Allele frequencies
The hardy-weinberg principle states that allele frequencies in a population do not change unless outside factors affect the gene pool.
Explanation;
Hardy-Weinberg principle is a mathematical model that describes how genotype frequencies are established in sexually reproducing organisms.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow.
