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.

Answer
no i don't know
Explanation:
i am so dum sorry if I can't help you
Answer:
E. Erwin Chargaff >> Discovered that there were equal amounts of the nitrogen bases A T and C G in a human body cell; concluded that A paired with T and C paired with G
B. Hershey and Chase>> Did experiments with viruses to determine that DNA, not protein, is the genetic material of a cell
A. Frederick Griffith>> Did experiments with S and R strain pneumonia bacteria to determine that DNA is the genetic material of a cell
C. Rosalind Franklin >> Took x-ray crystallography images of a DNA molecule.
Explanation:
Chargaff rules helped to determine the double helix structure of the Deoxyribonucleic acid (DNA), i.e., the genetic material of prokaryotic and eukaryotic organisms. Chargaff indicated that DNA from any species contains a 1:1 ratio of purine bases (Adenine and Guanine) and pyrimidine bases (Cytosine and Thymine). Hershey and Chase provided evidence that the DNA, instead of protein, is the hereditary material. Hershey and Chase used radioactive phosphorus-32 in order to label the DNA of specific bacteriophages (T2), and they discovered that the DNA was responsible to generate progeny inside infected bacteria (i.e., DNA was hereditary material). Frederick Griffith observed that DNA molecule was the transforming factor that could be transferred to innocuous <em>Streptococcus pneumoniae</em> bacteria in order to convert them into deadly bacteria. Finally, Rosalind Franklin obtained the first X-ray image that showed the diffraction pattern of a crystallized DNA molecule, which was used by Watson and Crick to propose that DNA had a double helix structure.
