Answer:

Explanation:

First off, nothing can be good or bad. Everything has pros and cons! Although earthworms definitely help the Earth meaning that it helps agriculture. Down below are a few pros and cons listed.

PROS

The worms alter the physical and chemical properties of soils. Meaning it changed the disrupting symbiotic relationship between soil fungi and roots.

Earthworms are actually a superfood! They're high in protein and have high levels of iron and of amino acids. (This requires a specific taste though!)

CONS

Worms include, coli O157 and salmonella. These bacteria can cause severe gastrointestinal infections in humans and are commonly found in soil.

The invasive worms are destroying the rich carpet of organic matter on the forest floor and may be causing a major shift in the delicate balance between the soil and the plants and the animals that need it to live.

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches

Each of the following phrases describes the structure, function, or regulation of either the hypothalamus, posterior pituitary,

juin [17]

Answer:

1) Hypothalmus: .D) Synthesizes some hormones that are released into blood vessels bound for another gland - G) Synthesizes oxytocin and ADH - H) Integrates nervous and endocrine systems.

2) Posterior Pituitary Gland: A) Releases oxytocin - F) Is an extension of the Hypothalmus

3) Anterior Pituitary Gland: B) Synthesizes and releases PRL - C) Synthesizes and releases TSH - E) Regulated by hormones released into portal blood vessels

Explanation:

The hypothalamus is the source of at least nine hormones that act stimulating on inhibiting other hormones secretion.

The first hypothalamic hormone discovered is the thyrotropin-releasing hormone, TRH, that stimulates the thyrotropin release by the hypophysis. Another important hormone is the gonadotrophin-releasing hormone, GnRH, that controls the release of gonadotrophic hormones, such as LH and FSH. The somatostatin hormone inhibits the release of somatotrophin hormone from the hypophysis. The oxytocin and the antidiuretic hormone are also secreted and released by the hypothalamus and collected by the posterior hypophysis from where they are then released again to the system.

The hypothalamus secretes hormones directly into capillaries forward to the anterior hypophysis. Oxytocin and antidiuretic hormone, instead, go to the posterior hypophysis through nerve fibers.

The hypophysis gland, also known as the pituitary gland, is located under the hypothalamus which controls the hypophysis. It is considered to be the master gland as it acts as a source of hormones that stimulates different organs. The hypophysis is conformed of three lobules: anterior, intermediate, and posterior.

The anterior lobule releases somatotrophin, prolactin, trophic hormones such as thyrotropin or TSH, ACTH, and gonadotrophins such as FSH and LH.

The posterior lobule collects and release the hormones secreted by the hypothalamus, such as oxytocin and ADH.

The hypophysis and the hypothalamus are both controlled by other parts of the nervous system.
