It is true that plants need salts and minerals to grow, but access salts can lead to the plant dying. (Like how humans need some salt in there diet, but access salt is not healthy. That is why it is bad to drink sea water) Anna's way of thinking is incorrect. Salty water could lead to the plant dying because too much salt could be toxic instead of helping them grow better.
Answer:
B. Gene expression is influenced by high lactose levels in the environment.
Explanation:
The lactose operon (lac operon) functions for the metabolism and transport of lactose in several bacteria.
Gene expression is influenced by high lactose levels in the environment as genes are expressed in the presence of high level lactose and absence of glucose. High level lactose carry an activator protein called catabolite activator protein (CAP), which let the RNA polymerase do transcription of the operon.
Hence, the correct option is "B".
