In animals the sensory capabilities evolved over hundreds of millions of years. It is therefore not surprising that different se

nsory aspects use similar transduction mechanisms. In terms of transduction (i.e., the way energy or chemicals are sensed and transduced into an electrical signal), which distinct human sensory systems use the same molecular mechanisms? Please list two pairs of systems and explain the similarity.

Answer:

Visual framework:  

In visual framework, sensory cells replace physical vitality of light signals into electrical motivations that movement to the mind. Tangible cells in visual framework are bar cells and cone cells. The light creates a conformational changes in rhodopsin. This change brings about a decrease of the electro-chemical inclination of the photo-receptor which brings about decrease of electrical signs setting off to the cerebrum.  

Aulfactory framework:  

In the olfactory framework the atoms that giving smell stuck the bodily fluid tough situation to G protein receptors on olfactory cells. The G protein does initiates a downstream flagging course that causes progressively level of cyclic AMP which causes synapse discharge

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)

Dose having yeast infection make one feel pain during sex?​
S_A_V [24]

Answer:

Explanation:

Having sex with a yeast infection can be very painful or, at best, extremely uncomfortable. If your labia or vulva are swollen, you may find skin-to-skin contact to be too rough. Friction may even rub the skin raw. Penetration can aggravate inflamed tissue, as well as increase itching and irritation
