Which of the outcomes could potentially result if a mutation in the gene encoding the Gα subunit eliminates its GTPase activity? Choose three outcomes. The signaling pathway could be activated for an extended period, possibly resulting in undesirable cell proliferation. Gα would be ineffective as a signal molecule (that is, it could not activate other proteins). The concentration of cAMP in the cell would be continuously elevated. The cell would be unresponsive to molecules that act via cAMP . Gα would be activated for an extended period. The rate of GTP hydrolysis would increase.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.  

hope its .

the real answer is b. scintillation counter

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
