Answer:

b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions

Explanation:

Red colored cars are more dangerous than other colored cars because red color cars can not be seen in the evening or dark environment so that's why more accidents were observed with red color cars as compared to another color cars. Red is a vibrant color and one of the most dangerous cars colors. People sometimes confused with traffic lights, brake lights etc and accident happen.

How does a swim bladder help the ray-finned fishes maintain buoyancy?A. Gas is added to the bladder as the fish's depth increase

NISA [10]

Answer:

A. Gas is added to the bladder as the fish's depth increases.

Explanation:

The swim bladder is a gas-filled organ localized in the dorsal region of Osteichthyes (bony fish) that allows them to regulate buoyancy, thus maintaining water depth without swimming. Since the swim bladder localizes in the dorsal region, it also functions as a stabilizing organ. This organ is composed of two sacs whose walls contract and expand in response to water pressure. The swim bladder contains an oval window that enables to adjust buoyancy in order to maintain a constant depth, or to ascend or descend in a wide range of water depths.

Potassium (K) and copper (Cu) are both in period 4. They both have _____.

Virty [35]

Answer:A): four electron shells

Explanation:

In the period table, atoms are arranged in rows called periods and columns called groups. The arrangement of atoms in groups is based on the number of their valence electrons while the arrangement of atoms across the periods is based on their number of electrons shells. Atoms are arranged across the periods in increasing order of their atomic number i.e., according to their number of electrons. Potassium has 19 electrons while copper has 29 electrons. Both has four electrons shells according to their electronic configuration.

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.
