This reserve is home to terrestrial and marine mammals, including grizzly and polar bears, caribou, wolves, and wolverine as well as beluga and bowhead whales, walrus, and several species of seals. It was established for the purpose of preserving unique wildlife, wilderness, and recreational values.


The most complex level of organizational hierarchy in the Arctic National Wildlife Refuge that is preserved is every ecosystem in the area.



I hope it helps, Regards.

sdas [7]

Portal blood vessels connect two capillary beds found in the hypothalamus and anterior pituitary.

So, the correct option is C.

<h3>Hypothalamus-Pituitary Complex:</h3>
  • The "command center" of the endocrine system is assumed to be the hypothalamus-pituitary complex.
  • In addition to hormones that directly affect target tissues, this complex also secretes hormones that control the production and release of hormones from other glands.
  • Furthermore, the hypothalamus-pituitary complex controls the communications between the nervous and endocrine systems.
  • The hypothalamus-pituitary complex is frequently necessary for the translation of a stimulus into hormones that can start a reaction after it is received by the neurological system.
  • Additionally, the pituitary gland (also known as the hypophysis), a bean-shaped organ hung from the hypothalamus by a stem called the infundibulum (or pituitary stalk), is physically and functionally connected to the hypothalamus.
  • The sella turcica of the sphenoid bone of the skull serves as a cradle for the pituitary gland.
  • It has two lobes, the posterior pituitary (also known as the neurohypophysis), which is made of neural tissue, and the anterior pituitary (also known as the adenohypophysis), which is made of glandular tissue.

<h3>Anterior Pituitary:</h3>
  • The embryonic anterior pituitary develops from the gastrointestinal tract and moves toward the brain as the fetus grows.
  • The pars tuberalis is a thin "tube" that wraps around the infundibulum, the pars distalis is the most anterior, and the pars intermedia is next to the posterior pituitary.
  • Neurons secrete hormones from the hypothalamus, but blood arteries transport them to the anterior pituitary.
  • There is a capillary bridge that links the anterior pituitary and hypothalamus inside the infundibulum.
  • The hypophyseal portal system is the network that enables the delivery of hypothalamic hormones directly to the anterior pituitary without first passing via the systemic circulation.
  • The superior hypophyseal artery, a branch of the carotid arteries that carries blood to the hypothalamus, serves as the system's initial point.
  • The hypophyseal portal system is made up of the superior hypophyseal artery's branches.
  • The portal veins deliver hypothalamic releasing and inhibitory hormones into the anterior pituitary via a main capillary plexus.
  • Anterior pituitary hormones enter a secondary capillary plexus in reaction to hormones being released, and from there, drain into the blood circulation.
  • In the anterior pituitary, seven hormones are produced.
  • Separate hormones produced by the hypothalamus either promote or suppress the anterior pituitary's capacity to produce hormones.
  • The hypophyseal portal system is the route by which hormones from the hypothalamus get to the anterior pituitary.
  • Seven hormones are produced by the anterior pituitary.
  1. Beta endorphin,
  2. prolactin,
  3. thyroid-stimulating hormone (TSH),
  4. adrenocorticotropic hormone (ACTH),
  5. growth hormone (GH),
  6. follicle-stimulating hormone (FSH), and
  7. luteinizing hormone (LH).
  • Because they regulate the activity of other endocrine glands, the anterior pituitary hormones TSH, ACTH, FSH, and LH are together known as tropic hormones.

The only way to send information back and forth is to use radio waves. Just like a radio station broadcasts a signal which you can listen to using a radio, astronauts and people on Earth can broadcast information back and forth to each other.
Radio waves are transverse waves.

Which of the following cells shows the presence of a nucleus?
statuscvo [17]
<span>The correct answer is Eukaryotic cell. The name itself shows that because prokaryotic means before the nucleus while eukaryotic means having a nucleus. Karyo is here from greek and means nut or kernel and pro means before, so those are cells before the creation of the nucleus. They are mostly bacteria but there are other types of beings too.</span>
