High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.

ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.

Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.

Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a
Anna71 [15]

The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.

  • Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
  • The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
  • Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
  • Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.

Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte
