Answer:
Arthropods invaded land about 100 million years before vertebrates. This fact most clearly implies that a. arthropods have had more time to co-evolve with land plants than have vertebrates
Explanation:
Arthropods are invertebrates animals. Its evolutionary ancestry dates back to the Cambrian period and they have had more time to co-evolve with land plants than have vertebrates. The vertebrates share a common ancestor. Scientists believe that the last common ancestor of all arthropods is a modular organism with each module covered by its own sclerite.
 
        
             
        
        
        
Answer:
Biomagnification also called food web magnification or food web accumulation is the progressive increase in the concentration of contaminants in organisms as the trophic level increases. These unexpectedly large concentrations are the result of DDT biomagnification up the food web.

Away from the ganglion The axon of a
ganglionic neuron is called a postganglionic fiber because it carries impulses.
an accumulation of extracellular fibrillar proteins and abnormal
dendrites and axons.  A “ganglion”
is essentially a living relay. The inputs are “pre-ganglionic” and the outputs
are “post-gangionic.” Simple.
 
        
             
        
        
        
 DNA, Chromosomes, Nucleus, Cell, Organism
Explanation:
DNA makes up the Chromosomes, which are stored in the nucleus, which is the brain of the cell, and cells make up organisms.
