Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
Answer:
a. Acts as a repressor (inhibits transcription from the lac operon)
Explanation:
LacI is a repressor protein that plays an important role in lac operon. Lac operon is usually switched off i.e. it is inactive in absence of lactose and presence of glucose. The operon has an operator region, promoter region and structural genes.
In absence of lactose, LacI repressor binds to the operator area. Since operator region overlaps with the promoter region, RNA Polymerase is not able to bind to promoter due to presence of repressor. Transcription of lac operon genes does not take place. When lactose is present, some of it is converted into allolactose. Allolactose binds to LacI repressor making it change its shape. The repressor is no longer able to bind to operator region and RNA Polymerase is free to transcribe the genes making the operon active.
Answer:
Option D
Explanation:
The cyst described in the question is the Bartholin's cyst usually felt as a soft and painless lump. It causes no issues when it is small in size but as it grows in size it causes vaginal pain while sitting, walking or having sex. The cysts becomes painful with time and develops pus known as abscess in the Bartholin's glands
