If all green plants in the world were distroyed which atmospheric gas will increase

Mila [183]

Trees are a crucial part of the carbon cycle, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

La polidactilia en la especie humana se debe a un alelo dominante. Entre Francisco y Martha, ambos abuelos de Santiago, uno de e

lesya [120]

Answer:

Abuelo/a con polidactilia heterocigoto, Pp
Abuelo/a normal, pp
Juan normal, pp
Esposa de Juan con polidactilia, PP o Pp
Santiago con polidactilia, Pp

Explanation:

Datos disponibles:

Polidactilia es causada por un alelo dominante, P.
El alelo recesivo p produce numero normal de dedos.
Francisco y Martha → Abuelos → uno de ellos con polidactilia
Juan → Hijo → Normal, pp
Santiago → Nieto → Polidactílico

Uno de los padres, ya sea Francisco o Martha, es polidactílico, lo que implica que ésta persona tiene, por lo menos, un allelo dominante en su genotipo, P- (El simbolo "-" esta representando un alelo dominante o uno recesivo).

Si Juan es normal, entonces su genotipo es pp, lo que significa que recibió un alelo recesivo de su padre y otro de su madre. Es decir que el parental policactílico es heterocigota, de forma que pudo heredarle un alelo recesivo a Juan. El otro parental probablemente sea normal, pp, pudiendo solo heredarle a Juan el alelo recesivo.

Entonces, uno de los padres tiene genotipo Pp (heterocigota) y el otro pp (homocigota recesivo).

Juan es norma, pp.

Santiago, hijo de Juan, es polidactílico, lo que implica que lleva en su genotipo por lo menos un alelo dominante, P. Pero Juan solo pudo heredarle un alelo recesivo, p. Por lo tanto, Santiago es heterocigota para la característica, Pp, y heredó el alelo dominante de su madre, que puede ser homcigota dominante PP o heterocigota Pp.

Supongamos que Francisco es polidactílico y Martha normal.

1º Cruza: Francisco x Martha

Parentales) Pp x pp

Gametas) P p p p

F1) 1/2 = 50% Pp

1/2 = 50% pp → Juan

2º Cruza: Juan x Esposa (opción uno: esposa homocigota dominante)

Parentales) pp x PP

Gametas) p p P P

F2) 4/4 = 100% Pp → Santiago

2º Cruza: Juan x Esposa (opción dos: esposa heterocigota)

Parentales) pp x Pp

Gametas) p p P p

F2) 1/2 = 50% Pp → Santiago

1/2 = 50% pp

Which immune component is deficient in a child who has a congenital immunodeficiency that impairs b lymphocyte function?

Artist 52 [7]

Neutrophils component is deficient in a child who has a congenital immunodeficiency that impairs B lymphocyte function.

Neutrophils- A specific kind of white blood cell that aids in the body's defense against infection and is crucial to the immune system. White blood cells are one of the initial immune cells to react when bacteria or viruses enter the body.

B Lymphocytes- By generating antibodies, B cells are essential for pathogen-specific immunity. Immunoglobulins attached to the surface of B lymphocytes allow them to identify soluble antigens, causing them to develop into plasma cells, which can secrete immunoglobulins and produce antibodies. Primary lymphoid tissues include lymphocytes.
