Answer:
It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Explanation:
Lac operon is also referred to as Lactose operon.This operon helps in the transport and metabolism of lactose of many enteric bacteria.
It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Due to the fact that it would be a total waste to produce enzymes when no lactose is available or if another preferable energy source such as glucose were available. The lac operon uses a two-part control mechanism to ensure that the cell uses energy producing the enzymes encoded by the lac operon only when necessary to avoid wastage and abnormalities.
At the outer edges of ocean crust
Explanation:
The rocks found in continents are older and in some cases the oldest. The younger rocks are found in mid ridge of ocean. The oldest rocks can be found in ocean trenches that are very deep.
At the outer edges of ocean crust, oldest rocks can’t be found as relatively newer ones are formed continually and mostly found. So, different regions have different ages of rocks and needs to be explored properly.
Eukaryote cells are single I’m pretty sure like it’s 1 thing
Answer:
There are 11 major organ systems in the human body.
Explanation:
The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
The nine major organ systems in the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.
