Please give me the answer to the A-level Biology Question Explain how anti-diuretic hormone (ADH) is released and acts on cells in the collecting duct wall?

Describe and explain how the lac Operon allows E coli bacteria to respond to environmental changes by regulating gene expression. The lac Operon is a set of genes that are regulated by an operator gene, which is activated by a specific inducer molecule. When this inducer molecule binds to the operator gene, it causes transcription of the genes in the operon, allowing E coli bacteria to produce proteins that allow them to respond to environmental changes. This process of gene regulation enables E coli bacteria t to quickly adapt to changing environmental conditions, allowing them to survive and thrive in their environment by regulating gene expression. To further Describe and explain how the lac Operon allows E coli bacteria t to respond to environmental changes, it is important to Describe how the lac operon works when lactose is both present and absent. Specifically, when lactose is present, the inducer molecule binds to the operator gene, activating transcription of the genes in the operon and producing proteins that allow the bacteria to respond to environmental changes. If the concentration of testosterone in a man’s blood starts to increase, this can also activate transcription of the genes in the operon. When lactose is absent, however, no transcription occurs and therefore no proteins are produced. Additionally, Could you explain the difference between passive diffusion and facilitated diffusion when it comes to how the lac operon works when lactose is both present and absent so that E coli bacteria can effectively regulate gene expression and adapt quickly to changing environmental conditions by responding appropriately depending on whether lactose is present or not. Furthermore, Describe How does Acetylcholine act on a neuronal synapse, and how is it affecting gene expression when lactose is both present and absent so that E coli bacteria can understand how this neurotransmitter affects gene expression and how it contributes to their ability to respond quickly to changing environmental conditions. Finally, Describe how the lac operon works when lactose is both present and absent so that E coli bacteria can effectively regulate gene expression and adapt quickly to changing environmental conditions by responding appropriately depending on whether lactose is present or not. Describe how the lac operon works when lactose is both present a so that E coli bacteria can understand how this process of gene regulation allows them to respond appropriately depending on whether lactose is present or not. To further explain this process, Describe how the lac operon works when lactose is both present and absent in order to understand how it regulates gene expression and allows E coli bacteria to respond quickly to changing environmental conditions, as well as How does Acetylcholine act on a neuronal synapse, and how is it affecting gene expression when lactose is both present and absent so that E coli bacteria can understand how this neurotransmitter affects gene expression and how it contributes to their ability to respond quickly to changing environmental conditions.
