¿Por qué la aparición de la comunicación celular fue un paso clave en la evolución de los organismos multicelulares?

Biology

Deffense [45]3 years ago
7 0

Answer:La transición de formas de vida unicelulares a multicelulares ha ocurrido en más de una ocasión a lo largo de la evolución. Las plantas, las algas marrones, los hongos y los animales han adquirido estilos de vida multicelulares de forma independiente y convergente.

La aparición de los animales representó un paso evolutivo clave en la historia de la vida. El desarrollo embrionario y todas las funciones que requiere la vida multicelular se hallan conservados en todos los animales, desde las esponjas a los humanos.

La secuenciación de los genomas de las especies unicelulares más cercanas a los animales ha revelado que estas ya contenían muchos de los genes necesarios para la multicelularidad. Estos habrían sido reutilizados para nuevas funciones multicelulares en el ancestro común de todos los animales.

What do photosynthesis and cellular respiration have to do with the law of conversation of mass and chemical reactions?
Tpy6a [65]
In plants, photosynthesis, occurring in chloroplasts, is an anabolic (bond-building) process whereby CO2 and H2O combine with the use of light (photon) energy. This yields O2 and sugar (i.e. glucose). This occurs in 2 phases: light-dependent and dark (Calvin cycle) reactions, which both continually recycle ADP/ATP and NADP/NADPH.
The catabolic (bond-breaking) process in plants is cellular respiration, in which glucose is broken down with O2 by glycolysis (cytoplasm only) and mitochondrial reactions (Krebs cycle and E.T.C.) to yield CO2 and H2O. These reactions recycle ADP/ATP and NAD/NADH. The CO2 and water produced by cellular respiration feed into the photosynthetic processes, and in turn, the O2 and glucose resulting from photosynthesis supply the respiratory reactions.

If Plant A with yellow flower (dominant trait) is crossed with Plant B white flower (recessive trait), what is the percentage of
marysya [2.9K]

Answer:

100%

Explanation:

Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:

       YY    x    yy

  Yy    Yy    Yy    Yy

All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.

<em>Hence, the percentage of the offspring that will have a yellow flower would be </em><em>100%.</em>
