pav-90 [236]

Answer:

Hypothalamus and anterior pituitary gland.

Explanation:

Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.

The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.

Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.

Monica [59]

Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.

Answer:

              1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.

2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged.  Electrostatic interaction also depends upon the nature and mass of body.  

b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
