They are not composed of cells. And one of eight characteristics of life say that all living things are composed of cells. Therefore, a virus would have to have in order to be considered a living thing.

A woman heterozygous for polydactyly (extra fingers and toes), a dominant trait, is married to a normal man. What is the probabi
Feliz [49]

Answer:

The correct answer is -50%

Explanation:

Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele

So, the heterozygous woman will be - Pp & the normal man will be - pp.  The presence of one allele of polydactyly will be able to show its effect as it is dominant.

Cross between heterozygous woman & normal man:

Gametes:

   P                              p

p Pp (Show polydactyly) pp (Normal phenotype)

p Pp (Show polydactyly) pp (Normal phenotype)

From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.

where can transcription and translation happen that is neither the cytoplasm nor the nucleus? And explain why.
xeze [42]

Answer:

We turn now to transcription in eukaryotes, a much more complex process than in prokaryotes. In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm.

Elodia [21]

un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): El que corresponde a lípidos son los triglicéridos.

Los resultados del estudio de sangre al que fue sometido Carlos son:

  • glucosa = 90 mg / ml
  • triglicéridos = 120 mg / ml
  • hemoglobina = 14 mg / ml
  • ácido úrico = 6 mg / ml

A partir del resultado dado, la opción que corresponde a los lípidos son los triglicéridos.

                  Los triglicéridos son lípidos (grasas cerosas) que proporcionan energía al cuerpo. Los triglicéridos son producidos por nuestro cuerpo y se obtienen de las comidas que ingerimos. Un triglicérido es un tipo de lípido compuesto por glicerol y tres moléculas de ácidos grasos.

                  La glucosa tiene la fórmula molecular C6H12O6 y es un azúcar simple. La glucosa es el monosacárido más ubicuo que es un tipo de carbohidrato. La glucosa es producida principalmente por plantas y algas cuando realizan actividad fotosintética a partir del agua y el dióxido de carbono con la ayuda de la luz solar, donde se utiliza para crear celulosa en las paredes celulares.

                  La hemoglobina es una proteína que se encuentra en los glóbulos rojos (RBC) que transporta oxígeno a los órganos y tejidos y transporta el dióxido de carbono (CO2) de los órganos y tejidos de regreso a los pulmones.

                  El ácido úrico es un producto de desecho que puede detectarse en la sangre. Se forma cada vez que el cuerpo descompone las purinas. La mayor parte del ácido úrico se disuelve en la sangre, viaja a través de los riñones y se excreta en la orina.

Por tanto, de la explicación anterior, podemos concluir que el resultado que corresponde al lípido son los triglicéridos.
