Answer:

The earth system is divided into four main components-Geosphere,,atmoshpere,hydrosphere and biosphere. These components are inetgrated with one another.

Explanation:

Geosphere (lithosphere) contains all the solid and semi-solid rock underneath the earth’s crust.

Hydrosphere: It contains all the earth’s water bodies

Biosphere: All living beings are exists on its

Atmosphere:It contains all the gaseous layers that surrounds the earth and held tightly by earth’s gravity.

Cryosphere:It is composed of all melting glaciers and polar ice caps of the mountains.

For billions of years all these layers are interlinked and  deeply affected one another.For instance,melting of glaciers and polar regions ice (cryosphere) returns to the oceans (hydrosphere) results sea level water rises which turn into floods and destroys the low-lying land (lithosphere) and affect coastal regions life (biosphere).

The function of antibodies is to A. inject toxins into living pathogens. B. mark pathogenic cells for destruction. C. act as Tol
Liono4ka [1.6K]

Answer:

Mark pathogenic cells for destruction. (Ans. B)

Explanation:

Antibodies are generated by the plasma cells, and once these secreted, they attach quickly to the surface of the toxin and stop the toxin from infecting the normal body cell by blocking key extracellular sites.

Antibodies also help to mark pathogens for destruction by the help of macrophages or neutrophils and they are known as phagocytic cells because they are highly excited to macro-molecules complexed with antibodies.

En un cruce entre peces naranjas y peces grises se obtiene una generación (f1) de 50% peces grises . Realice el cruce y explique
Ilya [14]

Answer:

Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).

Explanation:

<u>Datos disponibles:</u>

  • Cruce entre peces naranjas y peces grises
  • 50% de la F1 son peces grises
  • Naranja dominante sobre gris

Podemos nombrar el alelo dominante para color naranja <em>N</em>, y al alelo recesivo  para color gris <em>n</em>.

Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.

Supongamos que uno de los parentales lleva el genotipo <em>Nn</em>, y el otro parental es <em>nn</em>.

Cruce:

Parental)      Nn    x     nn

Gametas)   N    n       n    n

Fenotipos) Naranja     Gris

Cuadro de Punnett)      N           n

                            n       Nn         nn

                            n       Nn         nn

F1)  2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn

     2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,    

     nn

     50% de la progenie será color naranja (Nn)

     50% de la progenie será color gris (nn)
