How does the molecular clock work? It analyzes the brain functionality of two different species. It examines and compares the physical characteristics of two different species. It illustrates relationships between two different species. It compares the number of mutations that exist in the DNA of two different species.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

condensation. good luck!
