Answer:
<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone
<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis
Explanation:
Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.
<u>Explanation:</u>
Step 1:
All the sides of the cubes are equal.
Step 2:
Given,
a= 3 cm
Step 3:
Volume of the cube = a³
= 3 × 3 × 3
= 27 cm³
Hence, The volume of the cube is 27 cm³
Answer:
PICC lines are appropriate for long-term therapy and can easily be used in the home environment.
Explanation:
The most appropriate type of IV access for Elaine is a PICC line because the practitioner recommended home IV therapy for two weeks. These lines are actually the most appropriate because they can be used in places such as home environment and for long-term therapy.
A PICC line is a long, thin, flexible tube called a catheter. It is used to give you chemotherapy and other medicines. A doctor or nurse puts it into a vein above the bend of your elbow. It can stay in place until your treatment is over.
