Diffusion is important to organisms because it is the process by which useful molecules enter the body cellsand waste products are removed. Digested food molecules (amino acids, glucose) move down a concentration gradient from the intestine to the blood.
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.

Explanation:
Cortisol, a steroid hormone, is produced by adrenal cortex in adrenal gland located just above the kidneys. It is released in high stress situation and low blood glucose concentration. The effects include high increase in production of glucose through gluconeogenesis (breakdown of amino acids/proteins to glucose via deamination pathway), aids in metabolism of fats, proteins and carbohydrates and suppresses immune system.
Please see the attached flowchart diagram for a random concept. As you have not provided the labels, I am afraid I am unable to help you further in this regard.
Pedigree is identified as a family tree of genetics.
<h2>Phenotype probability</h2>
Explanation:
- In the given question,let say A is dominant allele and a is recessive allele
- Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
- When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%
