A. Directed by genes

Answer:

(a). directed by genes.

Explanation:

Natural selection can be defined as a process, by which organisms having favorable traits have more chance to survive and reproduce. Due to this, organisms with traits, which are adaptive for a given environment increase with each generation.

Organisms having favorable genes for a trait or behavior will have more chance to survive and pass these genes to next generations. Over time, natural selection will allow the organisms with favorable genes to adapt to their surrounding environment. Hence, for a behavior or trait to evolve under the influence of natural selection, the trait should be directed by genes.

Thus, the correct answer is option (a).

  • the je_rking of the knee
  • coughing or sneezing, when irritants enter the nostrils.

Reflex actions do not need to involve the brain, hence they occur very quickly.

The path of a reflex arc begins with a sensory receptor which receives the stimuli, travels to the spinal cord  through a sensory neuron which they initiates a response that is sent through a motor neuron to an effector such effector such as a skeletal muscle.

In conclusion, a reflex arc is the path of a reflex action through the body.
