An allele is best described as the alternative form of a gene.
<h3>What is an allele?</h3>
In genetics or cytology, an allele is one of a number of alternative forms of the same gene occupying a given position, or locus, on a chromosome.
Genes, according to Gregor Mendel, usually comes in pairs e.g. gene coding for height can be denoted by Tt. The allele represent a member of the gene that encodes a particular trait.
Therefore, an allele is best described as the alternative form of a gene.

Louis Agassiz established the first marine biology laboratory in the United States in order to help teachers at different levels to better capable themselves to teach natural history. He considered that learning from observations and first-hand analysis was perilous in attaining knowledge.
The laboratory was established in 1873 and was situated in Penikese Island that was situated just off the coast of Massachusetts. The school was called the Anderson Summer School of Natural History.
The statements of the old cell theory are:
1. All organisms are composed of cells
2. The cell is the basic unit of life
3. Cells are produced from existing cells
The modern cell theory's statements are:
1. The cell contains hereditary information which is passed to daughter cells
2. All cells are basically the same in composition and activity
3. All basic functions occur in cells
4. Cell activities depend on intracellular structures
As is visible from the statements, the old cell theory was not as detailed and lacked the understanding of the function, structure and behavior of cells that the current theory possesses. This difference has come about after years of research, through which scientists understood the functions of cells and elaborated on the theory's statements.
Answer:
Energy transferred to eardrum while listening to this sound for 1.0 min is 
Explanation:
Given
Sound waves of intensity 
Size of the ear drum i.e diameter 
millimeter
Radius of the ear drum
Time for which the eardrum will listen to this sound 
minutes.
As we know that the energy transferred to eardrum can be calculated by using below given relation
Where is the energy in Joules
I is the intensity in 
A is the area in 
and t is the time in seconds
Substituting the given values in above equation we get
Energy transferred to eardrum while listening to this sound for 1.0 min is
