The correct Answer is:
To determine how many sentences are wrong about prolactin, we will analyze each statement one by one: ### Step-by-Step Solution: 1. **Statement (A)**: "It is secreted by both the anterior pituitary and the placenta." - **Analysis**: Prolactin is indeed secreted by the anterior pituitary gland and during pregnancy, it is also secreted by the placenta. - **Conclusion**: This statement is **correct**. 2. **Statement (B)**: "It causes production of milk and ejection of milk from mammary glands." - **Analysis**: Prolactin is responsible for the regulation of milk production (lactogenesis) but does not cause the ejection of milk. The ejection of milk is primarily controlled by oxytocin, which is secreted by the posterior pituitary gland. - **Conclusion**: This statement is **wrong**. 3. **Statement (C)**: "Hyperprolactinaemia causes adverse effects on reproductive function in both male and female." - **Analysis**: Hyperprolactinaemia, which refers to elevated levels of prolactin, can indeed lead to reproductive issues in both males and females, such as infertility and decreased libido. - **Conclusion**: This statement is **correct**. 4. **Statement (D)**: "Receptors of prolactin are found in cell membrane and cytoplasm." - **Analysis**: Prolactin receptors are primarily located on the cell membrane. While some signaling may occur in the cytoplasm, the primary action of prolactin occurs at the cell membrane level. - **Conclusion**: This statement is **wrong**. ### Summary of Findings: - **Correct Statements**: A, C - **Wrong Statements**: B, D ### Final Count: There are **2 wrong statements** (B and D) about prolactin. ---

Make corrections wherever you find mistake in spellings/words in the following paragraph/sentences. (A) Protozoans are generally multinucleate, but all ciliates and many amoeboid types are uninucleate. (B) Contractile vacuoles are found in almost all terrestrial protozoans for maitenance of carbon concentration of cell body, the phenomenon is known as osmoregulation. Contractile vacuole also helps in reproduction. (C) The protozoan cell body is either naked or surrounded by a rigid pellicle. Cellulose is present in pellicle. Some protozoans secrete shells of various organic compounds as external covers. (D) Ascomycetes are coenocytic as well as multicellular fungi. In the later, mycelium is asceptate. The asexual spores are formed in chains are called zoospores. The spores are formed endogenously, i.e., inside sporangium. (E) Sexual reproduction in Rhizopus is oogamous and the mode of sexual fusion is gametangial contact type. (F) A lichen is structurally organised entity consisting of the permanent association of a fungus and an alga. The fungal component of a lichen is called phycobiont and the algal component is called mycobiont. Both mycobiont and phycobiont are associated in parasitic union in which the fungus is more predominant and alga is subordinate partner.
