Answer:

A neuron that has only one axon but several dendrites is classified as:

a. multipolar neuron.

Explanation:

  • The neurons are the fundamental unit of the nervous system.
  • The nervous system consist of only two types of cell; neurons and neuroglia.
  • Neurons are specialized to respond to physical and chemical stimuli, conduct nerve impulse and release neurotransmitter , while the neuroglia supports , nourish and protect the neuron.
  • Most neurons have three parts: a cell body, dendrites and axon.
  • Neurons show a great diversity in size and shape, and are classified on the basis of structure and function.

On the Basis of structure the neurons are classified as: unipolar, bipolar and multipolar. (Multidendritic neurons are studied in <em>Drosophilla </em>and are reported to be a result of misexpressed<em> gene</em>)..

  • Multipolar neurons are the most common type of neurons in the brain and spinal cord and have several dendritic processes and one axon.
  • Bipolar neurons  are found in retina of the eye, in the inner ear and in the olfactory area of the brain and are characterized by one dendrite and one axon.
  • Uni-polar neurons have single processes extending from the cell body which divide into two branches.

On the basis of function neurons are classified as; sensory, motor and association neurons.

A ____ is the underlying combination of genetic material present (but outwardly invisible) in an organism.
Alex

Answer:

D (Genotype)

Explanation:

A genotype is the genetic make up of an organism i.e. what the genetic material

of an organism constitutes. Genotype describes the set of genes contained in an organism's genome. According to Mendel, an organism receives two forms of genes called ALLELE for a trait, one from each parent. The genotype of a specific gene coding for a trait is represented by each pair of allele for that trait.

Although the genotype of an organism is outwardly invisible i.e. cannot be seen, but it determines the phenotype of that organism i.e. the outward appearance. For example, if a plant receives T and T alleles coding for tallness, from each parent. The genotype of that plant for the specific height trait will be (TT). Hence, the TT genotype although invisible but controls the tallness of the plant.
