Answer:
This mutation will produce a conformational change capable of maintaining the receptor continuously in its activated mode
Explanation:
G proteins are inactive when guanosine diphosphate (GDP) is bound, while they are active when guanosine triphosphate (GTP) is bound
Some afferent neurons are sec specialized to detect stimuli, whereas efferent neurons send signals to the effectors of the nervous system.
The best and most correct answer among the choices provided by your question is the second choice.

Answer:
A. Calcium would be transported to the sarcoplasmic reticulum therefore contractions would cease.
Explanation:
A muscle fibre will stop contraction immediately ATP is used up. Also, muscle contraction will end as soon as the information from the motor neuron stops. This repolarizes the sarcolemma and T-tubules, thereby closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are then pumped back into the sarcoplasmic reticulum, in order for tropomyosin to cover the binding sites on the actin strands again.
Answer:
The correct options are B "The unusual F1 female is heterozygous for a reciprocal balanced translocation involving the chromosome with the apricot, bristle and clipped loci" and D "Independent assortment of non-compatible chromosome structures (i.e., translocated and normal chromosomes segregating together) in the F1 female led to the 90 eggs that aborted development"
Explanation:
The unexpected results obtained earlier can be attributed to the two factors listed above. At the time when meisois takes place, there is the process of independent assortment which leads to formation of zygotes. Due to the event of translocation, the eggs produced lacked some critical development genes.
