Answer:
the system used to classify and group living organisms
Explanation:
True because they are selecting and breeding for traits that will be best for survival
Answer:
Option B, Biology requires that humans eat a certain amount each day, but culture teaches us what we want to eat, when we want it, and how to eat it.
Explanation:
As per biology, all living individuals require energy for doing their day to day activities and also to survive. This energy is obtained through food. Food provides essential nutrients and minerals and energy to the body that helps the body to survive, grow and develop.
Now a culture defines what to eat and how to eat for instance in some culture only vegetarian food is allowed and in some both vegetarian and non-vegetarian food is allowed for consumption.
Also the timing of eating are defined by the preachers of the culture.
Hence, option B is correct
The question is incomplete. The complete question is as follows;
Examine and characterize the two motor pathways in the stretch patellar reflex.
A) Alpha motor neurons send efferent messages to the quadriceps, while parallel efferent messages to the hamstrings are reduced.
B) Alpha motor neurons send efferent messages to excite the quadriceps and the hamstrings are reduced.
C) Alpha motor neurons activate the quadriceps. Once the quadriceps have contracted, alpha motor neurons inhibit the hamstrings.
D) Interneurons excite alpha motor neurons, which in turn excite the muscle.
Answer:
Alpha motor neurons send efferent messages to the quadriceps, while parallel efferent messages to the hamstrings are reduced.
Explanation:
Neuron is the structural and functional unit of the nervous system. The neurons can be classified as sensory neuron, motor neuron and interneuron based on their function.
The knee reflex is known as patellar reflex that involves in the movement of knees and stretching of patellar tendon. The efferent message is send by alpha motor neuron that are located in the anterior horn of the spinal cord. This send to quadriceps that results in the muscle contraction. In this process, the hamstrings messages are reduced that plays an important role in patellar reflex.
Thus, the correct answer is option (A).
