A neuron is a nervous system cell specialized in the communication and information processing between the nervous system and the various organs. It is present under different structures (multipolar, unipolar, bipolar ...).It consists of three main parts:
*A cell body also called soma, it is composed of the cytoplasm and the nucleus of the cell that contains the DNA to encode the proteins necessary for the function of the neuron.
*Tree extensions that are also called dendrites, its role is to receive information.
*A single axon with the ability to route information to other cells.
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.

Answer:
Ecosystem is the the name of the natural or artificial system in which living organisms interacts with the non-living physical environment. The living components are called as biotic factors which includes plants, animals, birds and human beings. The non-living components includes sunlight, temperature, weather conditions, water and soil. The living components of the ecosystem are dependent on non-living components for performing their biological functions like respiration, photosynthesis and others.
