<span>Variations in asexual organisms are rather rare since they occur as a result of mistake of mitosis during DNA copying. On the other hand, variations in sexual organisms are a result of fusion of two different gametes that carry different traits. Thus, the offspring carries characteristics of both parents, resulting in greater genetic variation within the next generation. Consequently, sexual organism obtain greater genetic variation than asexuallt reproducing species.</span>
Answer:
evaporate, bend, melt, dissolve
Explanation:
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.
Without a charge, it would be 35 electrons. Protons have a positive charge and electrons negative. They must balance each other out, otherwise the atom will be charged.
