1 Identify the hormones (and their functions) of the hypothalamus and the anterior and posterior pituitary glands in homeostasis
Valentin [98]

1.The hormones of the hypothalamus and the anterior and posterior pituitary gland are antidiuretic hormone and oxytocin and ADH.

<h3>What hormones are produced by the hypothalamus and their functions?</h3>

The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.

2. The endocrine glands on models  are :

  • hypothalamus.
  • Hypophysis.
  • Thyroid gland.
  • Parathyroid glands.
  • Islet cells of the pancreas.
  • Adrenal glands.
  • Testicles in men and ovaries in women.

<h3>What are the general characteristics of the endocrine glands?</h3>

The main feature of endocrine glands is the absence of excretory ducts. The service product produced by endocrine cells is transported to the extra diffusion space, reaching the interior of blood vessels.

3. When an imbalance of the endocrine system occurs, it results in Hormonal disorders can be caused by various factors such as diabetes, psychological changes, stress, eating disorders, regular use of medication and cancer.

Which statement about RNA is not true? Uracil is found in RNA as one of the two pyrimidine nitrogenous bases. RNA possesses cata
mash [69]

Answer: RNA is a more stable molecule than DNA

Explanation: DNA (deoxyribonucleic acid) is much stable than RNA (ribonucleic acid) for many reasons; Frist of all its because of the double strand of the DNA versus the single-stranded RNA. This is thanks to the Hydrogen bonding between bases since those bondings release free energy that allows the molecule to be provided by more thermodynamic stability.

Also the lack of 2′ OH groups makes DNA more stable since the OH groups are very reactive by themselves. In the DNA sugar molecule there is not a spare OH group that could start reacting on its own. So this is why DNA is immune to chemical reactions, while RNA (having an extra OH group) is more chemically "promiscuous".
