La respuesta correcta para esta pregunta abierta es la siguiente.

Los tres avances científicos más importantes, a través de la historia para la humanidad son los siguientes.

1.- El descubrimiento de la penicilina.

El científico Inglés Alexander Fleming fue el descubridor de la penicilina en septiembre de 1928. Este descubrimiento revolucionó la historia de la humanidad.. Antes, millones de personas morían debido a las infecciones en el cuerpo humano. La penicilina resultó ser el antibiótico más efectivo descubierto hasta el día de hoy y ha salvado millones de vidas humanas desde su descubrimiento.

2.- El descubrimiento de la electricidad.

¿Te puedes imaginar un día de tu vida sin luz?

Bueno, pues así vivió la gente toda la vida hasta el siglo XVIII, cuando comenzó a entenderse y desarrollar mejores maneras de producir electricidad. Prácticamente todos los aparatos electrodomésticos, de laboratorio, hospitales, en oficinas, escuelas y demás, funcionan con electricidad. Sin ella, nuestra vida no habría producido los avances que conocemos el día de hoy.

3.- El internet.

La revolución de este siglo.

El internet nos mantiene conectados todo el tiempo a cualquier parte del mundo. Con el internet podemos hacer miles de cosas desde nuestras computadoras y teléfonos celulares, que hasta hace 15 años eran inimaginable.

Ronch [10]

Answer:

desiccation tolerance, alternation of generation

Explanation:

  • Adaptation to life on land, took place by desiccation tolerance that is the ability of the organism to stand or endure extreme dryness and the alternation of generations such as the life cycle changes in which the haploids and diploids change or show haplodiplontic.  
  • The development of the phloem and xylem tissues for distribution of water and intake up of minerals from the soil. Development of stem for gas exchange. Some plants have defense strategies for the dry environments such as seedless sprout growth.

If a female fruit fly heterozygous for red eyes (X RX r) crossed with a white-eyed male (X rY), what percent of their offspring
Gre4nikov [31]

Answer:

6.25%

Explanation:

Given that:

The trait of a female fruit fly that is heterozygous for red eyes = XRXr;   &

The trait of a white-eyed male is XrY_ ;

since Y is dominant y; the male trait can either be XrYR or XrYr

So, let assume that it is XrYr

Then; if each trait self crossed; we have:

XRXr = XX    Xr    XR    Rr

XrYr = XY    Xr     rY    rr

Thus, the punnet Square can be computed as:

               XX             Xr             XR           Rr

XY         XXXY       XXYr         XXYR        XRYr

Xr          XXXr         XXrr          XXRr        XRrr

rY          XrYX          XxYr         XrYR        RrYr

rr            XrXr          Xrrr           XrRr        Rrrr

∴

the percentage of offspring that would have white eyes XrY_ is:

1/16 = 0.0625

= 6.25%
