Answer: This is what I could find on it.
There are many external factors that can disrupt homeostasis. Disease, toxins, and pathogens are just a few examples.
Some diseases can have external causes, like a toxin or pathogen invading the body. Toxins are products of plants, animals, fungi, or bacteria that hurt cells in some way.

Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
The answer is e. Calcitonin, Aldosterone and Atrial natriuretic peptide.
The calcitonin is a hormone secreted by the thyroid gland. Calcitonin is involved in the regulation of the levels of calcium and phosphate in the blood. Aldosterone is a hormone secreted by the adrenal gland. It is essential for maintaining the store of sodium in the kidney, salivary glands, sweat glands and colon. Atrial natriuretic peptide (ANP) or Atrial natriuretic factor (ANF) is a peptide hormone synthesized, and secreted by cardiac muscle cells in the heart. ANP is involved in the regulation of sodium levels in the cells of the heart.
Axons of the spinal nerve that innervate the ventrolateral body surface, structures of the body wall, and limbs make up the Ventral ramus.
The anterior portion of a spinal nerve is known as the ventral ramus. Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, the ventral ramus, and the ramus communicans. These contain information that is both sensory and motor.
The sensory and motor fibres that innervate the muscles, joints, and skin of the lateral and ventral body walls as well as the extremities are carried by the spinal nerves' ventral ramus. They continue to be separate from one another throughout the thoracic region and each innervates a small section of muscle and skin along the sides, chest, ribs, and abdominal wall.
