Answer:
Axon.
Synapse
Dentrite and cell body.
Explanation:
AXON is the transmission conduit for action potential through saltatory conduction at the nodes of ranvier.
Synapse refers to the gap between adjacent nuerones and the entire components of that particular gap.
Denrites which originated from the cell.body received the transmitted signals from.the axon,and transmits this for response at effectors:muscle and glands.
 
        
             
        
        
        
Answer: diversity of niches
, large area and warm climate
Explanation:
An ecosystem is a biotic community in which the living beings interact with their non-living physical environment. The following factors which are responsible for higher biodiversity in an ecosystem:
Diversity of niches: A niche can be define as the functional role an organism performs in an ecosystem so as to sustain it's life. For example the type of habitat, food and breeding season chosen by the organism. With the increase in the differences in the diversity of niches the organism exhibit variations and differences from the members of the same species or from the members of the other species.
Large area: The large area can support the reproduction and abundance of members which belongs to different species hence will help in promoting higher biodiversity in a region. 
Warm climate: The warm climatic range will offer the chances of adaptations to the living organisms to sustain their lives in harsh environmental conditions. This will lead to evolution of  new species from the parent species.

DNA or deoxyribonucleic acid is the molecule in living organisms wherein the genetic code or <em>genes</em> is stored. The structural conformation of DNA in the nucleus of the cells is called <em>chromatin </em><em />and in cell division, chromatin is grouped into a certain number (46, in humans, for instance) called <em>chromosomes.
</em>DNA provides instructions for hereditary such that a part of DNA is transcribed into messenger RNA or mRNA for the genetic code to be transported outside the nucleus. The mRNA is then translated into polypeptides to form proteins that form specific functions in the human body.<em>

Hi! human,dog are multicellular organisms. Nucleus,cell membrane, cytoplasm and mitochondria are 4 things that plant and animal cells have.
