How does human impact on freshwater ecosystems by carbon cycle and environmental impact

sp2606 [1]

Answer:

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Un hombre que carece de la posibilidad de enrollar su lengua (ee) se cruza con una mujer heterocigoto para este rasgo que enroll

Valentin [98]

Answer:

50%

Explanation:

La información que tenemos es:

Un hombre homocigoto (ee) que carece la posibilidad de enrollar su lengua.

Una mujer heterocigota (Ee). Al tener dos copias distintas de este gen, la mujer puede enrollar su lengua ya que este es un gen dominante (E) sobre el gen recesivo (e) que impide este movimiento.

Si hacemos un Cuadro de Punnett veremos que la capacidad de enrollar la lengua en los descendientes de esta pareja tiene una probabilidad fenotípica del 50% ya que hay un 50% de probabilidades de que su descendencia tenga un genotipo Ee y otro 50% de que sea ee, lo cual se expresa en una probabilidad fenotípica, es decir lo que se puede apreciar visiblemente como resultado de la interacción del genotipo y el ambiente, de con un 50% de poder enrollar la lengua.

Cystic fibrosis is an autosomal recessive disorder. In one population, the frequency of affected individuals (A 2 A 2) is 0.0004

Simora [160]

Hardy Weinberg Equilibrium

Explanation:

Hardy Weinberg Equilibrium formula for allelic frequency is: $p+q=1$

Hardy Weinberg Equilibrium formula for genotypic frequency is: $p^2+q^2+2pq=1$

Here, $p$ =frequency of dominant allele

$q$ =frequency of recessive allele

$p^2$ =frequency of dominant genotype

$q^2$ =frequency of recessive genotype

$2pq$ =frequency of heterozygous genotype

frequency of affected individuals=0.0004(given)

here,affected individuals means the one's having Cystic Fibrosis and since it is recessive disease so we can write frequency of recessive genotype as: $q^2$ =0.0004

If $q^2$ =0.0004 $q$ will be 0.02;frequency of recessive allele will be 0.02

Using the formula $p+q=1$

$p+0.02=1\\p=1-0.02=0.98$

hence,frequency of dominant allele will be 0.98

Frequency of dominant genotype will be $p^2=(0.98)^2=0.9604$
Frequency of heterozygous genotype will be $2pq=2*0.98*0.02=0.0392$
