The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l
serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and  homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

              BS                     BS                  BS                BS

BS          BBSS                BBSS            BBSS             BBSS        

Bs          BBSs                 BBSs            BBSs              BBSs

bS          BbSS                BbSS           BbSS              BbSS

bs          BbSs                 BbSs            BbSs              BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and  homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

irina1246 [14]

Answer:

enfermedad  

Explanation:

De acuerdo a la Organización Mundial de la Salud (OMS) el término enfermedad refiere a la alteración y/o deterioro del estado fisiológico normal de un individuo o partes de su cuerpo, cuyas causas a menudo son conocidas. A su vez, una enfermedad es conocida cuando possee un cuadro clínico con síntomas preestablecidos y característicos. Las enfermedades se pueden clasificar de acuerdo a muchos tipos diferentes de parámetros (por ejemplo, de acuerdo a su modo de transmisión en infecciosas/no infecciosas, hededitarias/ambientales, etc). Por otra parte, el concepto de salud se refiere a un estado de bienestar físico, mental y social del individuo, el cual no solamente está asociado a la ausencia de enfermedades.
