It is because science requires a lot of replication to confirm results. Like in the scientific method, you need to use standard units to analyze your results and to see if your experiment proves that your hypothesis is correct.
hope this helped :) Have a great day
Answer:
An autoimmune problem involving the thyroid gland: C. Graves' disease
Hyposecretion of growth hormone: Pituitary dwarfism
Hyposecretion of the pancreas: E. Diabetes mellitus
Hyposecretion of the adrenal cortex: B. Addison's disease
Hypersecretion of growth hormone: A. Acromegaly
Explanation:
Growth hormone is the hormone from the anterior pituitary gland that targets the tissues such as muscles, bones, cartilage, liver, etc. and stimulates the somatic growth of the body. Its hypersecretion leads to acromegaly in adults while its hyposecretion causes dwarfism in children characterized by stunted growth. There is abnormal thickening of specific bones in acromegaly.
Pancreatic hormone insulin serves to lower down the blood glucose levels. Insulin deficiency causes diabetes mellitus characterized by higher blood glucose levels in the affected person.
Hyposecretion of glucocorticoids and mineralocorticoid from adrenal cortex causes Addison's disease characterized by rapid weight loss, lower levels of glucose and sodium in plasma while a rise in potassium levels.
Grave's disease is an autoimmune disease wherein the thyroid gland is stimulated for increased secretion of thyroxine resulting in protruded eyeballs.
Angiosperms have seeds protected by an ovary which develops into the fruit.
The neonatal period is the first 4 weeks of a child's life. It is a time when changes are very rapid. Many critical events can occur in this period: Feeding patterns are established. Bonding between parents and infant begin
Before the baby is born, blood goes through the placenta to get rid of waste and to pick up oxygen and nutrients that come from the mother. The developing baby manages on relatively low oxygen levels while in the uterus. After birth the child is exposed to suddenly higher (potentially dangerous) oxygen levels

1) the S-phase before mitosis nd meiosis
2) the number of chromosomes only doubles when two haploid gametes form to produce a diploid zygote. for example: in humans, the sperm cells and eggs have 23 chromosomes , which is the haploid number.
