Answer:
C. Bind and maintain high concentrations of testosterone in the seminiferous tubules.
Explanation:
Seminiferous tubules are present within the testis of male reproductive system. In adults, each testis is oval in shape and is about 4-5 cm in length. Each testis has about 250 compartments called testicular lobules. These compartments contain highly coiled tubules called seminiferous tubules.
Within the seminiferous tubules, the male gamete i.e sperms are produced. Seminiferous tubules are lined inside by two types of cells called male germ cells (spermatogonia) and sertoli cells.
Spermatogonia give rise to spermatozoa which are released into the lumen of the tubule. In between spermatogenic cells, sertoli cells or sustentacular cells or nurse cells are present which provide nourishment to developing spermatozoa.
One of the function of sertoli cells are to release androgen binding protein (ABP) which binds and concentrates testosterone with in the seminiferous tubules.
The hormone testosterone is produced by the interstitial cells of Leydig located around the seminiferous tubules.
Answer:
I think my answer will be none
Explanation:
it's kinda stupid options. it should be that it's a part of biosphere then maybe it'll get a little closer to the right answer then u can choose option a
hope it helps
Osmosis is the process; it is essentially diffusion, which is a spontaneous (no energy input required) process as applied to water.
----------------------------
Hydrolysis is incorrect; that describes a type of chemical reaction in which water breaks a chemical bond.
Photosynthesis is incorrect; that describes the complex process in which energy in light is converted into chemical energy.
Cyclosis is incorrect; that describes the movement of cytoplasm within a cell. There is no spontaneous, net movement of water across a concentration gradient.
The answer is to assess the Rh or as called as rhesus of the baby. In addition, the cord blood should be evaluated to determine the Rh type of the infant. If it is negative, there is no need for any further action or concern. However, if it is Rh positive the mother needs to be evaluated for possible supervision of RhoGAM.
The measures for giving RhoGAM are as follows:
• The woman must be Rho (D) negative.
• The woman must not have anti-D antibodies which are must not be sensitized.
• The infant should be Rho (D) positive in which the fetus cord blood is checked after birth.
• A direct Coombs test which is a test for antibodies performed on cord blood at delivery and must be weakly reactive or negative.
All of these requirements to be accomplished in the first 72 hours of birth, so the mother can obtain RhoGAM in the appropriate time frame.
