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

Deffense [45]3 years ago

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.

I had a room full of 666 cockroaches which included 24 albinos. These albinos were so scary looking that I squashed them with a
Aleks04 [339]

Answer:

Number of albino cockroaches = 486 cockroaches

Explanation:

Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of cockroaches having similar alleles for the dominant trait;

2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.

q² = 24/666

q² = 0.036

Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.

Number of albino cockroaches = 0.036 × 13485

Number of albino cockroaches = 486 cockroaches
