Answer:
Cystic fibrosis
Explanation:
X- linked trait may be defined as the trait that is located on X chromosome or the inheritance of the trait is based on the X chromosome. The disorders associated with X-linked trait is known as sex linked disorder.
Cystic fibrosis is an autosomal recessive disorder that affects the digestive system, lungs and liver. The homozygous recessive condition is responsible for the disease cystic fibrosis. Hence, cystic fibrosis is not an X-linked trait.
Thus, the correct answer is option (2).
The tumor suppressors allele is analogous to the brake pedal in a vehicle while cyclins are like the gas pedal. The tumor supressors regulate, negatively, the replication of cells. If the tumor supressor is mutated, this is analogous to the brake pedals of the vehicle being broken, This means that if two are broken, then the vehicle will be unable to stop and will continue moving. This same way, if tumor suppressors are mutated, the replication of cells will continue unregulated and casue a tumor.
Answer:
b) release of chemical messengers into the space between the axon of the sensory neuron and the plasma membrane of the interneuron
Explanation:
The space between the axon of the sensory neuron and the plasma membrane of the interneuron is called synapse. It is the junction through which neurons communicate. There are two types of synapses:
- electrical-ions flow directly between cells
- chemical-neurons communicate using chemical messengers
