To send information from the brain or spinal cord to muscles and glands - is the purpose of motor neuron
Explanation:
As part of the central nervous system (CNS), the motor neurons connect the brain and spinal cord to all the muscles and glands present all over the body and innervates them.
Their main function is to transmit nerve impulses from the CNS to the muscles, both skeletal and smooth, and directly controls the movements of the muscles of the body.
A motor neuron is a typical nerve cell with multipolar body. It can be upper of lower motor neuron.
Right from snapping of fingers to movements of hamstrings, all muscular movements functions due to impulse carried by the motor neurons.
Degeneration of the motor neurons leads to neurodegenerative diseases like spinal muscular atrophy or amyotrophic lateral sclerosis.
Answer: This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids in the stomach. When the stomach digests food, the carbohydrate in the food breaks down into another type of sugar, called glucose

Answer:
Organism's parent.
Explanation:
Trait can be defined as the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Simply stated, a trait refers to the distinguishing characteristic or quality of any living organism.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
For example, John is so tall and has a curly hair, it's obvious he acquired the trait from his mum.
In Genetics, a trait comprises of all the genetic instructions that are typically being transfered from the parent to their offsprings.
Hence, an organism inherit its genetic instructions from its parent.
Answer:
Option (3).
Explanation:
The homeostasis of the body is maintained by the feed back loop system. Two main types of the feedback loop system of the body are positive feedback system and negative feedback system.
Positive feedback system may be defined as the feedback in which the final product increases the output of that product. Pepsinogen is an zymogen that helps in the activation of pepsin enzyme. This enzyme helps in the digestion of protein. The digestion of pepsinogen by pepsin result in the more production of pepsin.
Thus, the correct answer is option (3).
