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>
Answer:
Culturing of microbial organisms allows experts to determine what type of organism is present and at what conditions it abundantly exist. This is an essential tool to determine the cause of contagious/infectious disease so that experts will have a clear understanding how to combat it.
Explanation:
Answer:
The correct answer is D.
Explanation:
Sperm is produced in the seminiferous tubules of the testes, then it travels through the straight tubules and the rete testis and arrives at the <u>epididymis to mature and to be stored.</u>
When ejaculation occurs, sperm leaves the epididymis through the vas deferens and arrives to the ejaculatory duct. Then ejaculatory duct passes through the prostate to merge witch the urethra and finally sperm leaves the body.
