Answer:There are Multiple different types of energy transfer, including gravitational potential energy, elastic energy, and kinetic energy.
Explanation:When you use your potential energy to jump, the trampoline uses its potential energy in its springs to push back against you.
Answer:
Hormones that act on the target cells to increase metabolism are Triiodothyronine (T₃) and Thyroxine (T₄).
Explanation:
The hormones triiodothyronine (T₃) and thyroxine (T₄) are the active forms of thyroid hormone, responsible for increasing cell metabolism.
Both T₃ and T₄are produced by the thyroid gland, in response to the pituitary hormone TSH. T₄ is more abundant but less powerful than T₃
Thyroid hormones are responsible for controlling cell metabolism, since their increase determines an increase in metabolism, and their deficiency slows it down.
The other options are not correct because:
- <em><u>Thyrotropin Releasing Hormone (TRH)</u></em><em> is produced by the hypothalamus to activate the production of TSH in the pituitary gland.</em>
- <em><u>Thyroid Stimulating Hormone (TSH)</u></em><em> is a pituitary hormone in charge of activating the production of T₃ and T₄ in the thyroid.</em>
- <em><u>Adrenocorticotropic Hormone (ACTH)</u></em><em> is produced by the pituitary gland to stimulate the production of hormones in the adrenal cortex.</em>
