The correct answer would be D. because the patient's eyes have oddly shaped corneas. I really hope that this help's. I just moved to the U.S. so please dun't be mad at me if it's wrong.

Answer:

The patient’s eyes are too short.

Explanation:

A person can focus clearly on objects both near and far that means a person's vision is normal.

But when a person cannot focus clearly on objects both near and far then it means that the person is suffering from two defects.

(I) Long sight :

In this defect, the person cannot focus on the nearest object but he can focus clearly on distant objects.

Because his eyeball is too-short and the light is focused at a point behind the retina.

This defect can be correct by using convex lens.

(II) Short sight :

In this defect, the person cannot focus on the distant object but he can focus clearly on near objects.

Because his eyeball is too-long and the light is focused at a point front of retina.

This defect can be correct by using concave lens.

Hence, A doctor suggest converging lenses to correct a patient's vision.

Because The patient's eyes are too short.

Complete el cuadro de Punnett que muestra un cruce entre un hombre que es heterocigoto para el tipo de sangre B y una mujer que
mylen [45]

Answer:

F1) 1/4 = 25% de la porgenie será AB, IAIB

     1/4 = 25% de la progenie será heterocigota para el tipo A, IAi

     1/4 = 25% de la progenie será heterocigota para el gruo B, IBi

     1/4 = 25% de la progenie será homocigota recesiva, ii

Explanation:

  • El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I.
  • En personas de tipo A, los alelos son IA dominante, i recesivo.
  • En personas de tipo B, los alelos son IB dominante, i recesivo
  • IA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.  
  • El alelo i es recesivo siempre.

Genotipo A:

  • IAIA, Homocigota dominante
  • IAi, Heterocigota
  • ii homocigota recesivo

Genotipo B:

  • IBIB, Homocigota dominante
  • IBi, Heterocigota
  • ii homocigota recesivo

Genotipo AB:

  • IAIB, Homocigota dominante

Cruza: un hombre que es heterocigoto para el tipo de sangre B con una    

           mujer que es heterocigota para el tipo de sangre A

Parentales) IBi    x    IAi

Gametos)  IB    i      IA    i

                      IB          i

             IA    IAIB       IAi

               i      IBi          ii

F1) 1/4 = 25% de la porgenie será AB, IAIB

     1/4 = 25% de la progenie será heterocigota para el tipo A, IAi

     1/4 = 25% de la progenie será heterocigota para el gruo B, IBi

Otrada [13]

The potato crop devastation occurred in Ireland for not using one single potato species.

Explanation:

Potato became the staple crop of 18th Century Ireland and was easy to grow in the soil of this place.  Later, it became the most dependent crop of the people of Ireland which made its supply very demanding leading to the yielding of more than one species of potatoes.

This yielding reduced the variety in the genetics of potatoes that helped in preventing the disease that affect potatoes by making the Irish people susceptible to famine. The Phytopthora bacteria affected the potatoes of North America in the year 1840 and Ireland’s moist weather in that same year made the blight to thrive.
