The extracellular glucose inhibit transcription of the lac operon (D) by reducing the levels of intracellular cAMP.
Lac operon is the assembly of various genes that are involved in the uptake and metabolism of lactose of E. coli or any other bacteria. It consists of a regulator gene, promoter gene, operator and structural gene. Structural genes are three: z, y and a. Each codes for a different enzyme.
cAMP is the cyclic Adenosine Monophosphate. It is produced by the bacteria when there are low levels of glucose in it. Hence it is also named as hunger signals. Therefore, cAMP is responsible for activating the operon to produce lactose.

Answer:
A dolphins are mamals because they give live birth.
Explanation:
According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
<h3>What are uni-axial synovial joints?</h3>
They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.
In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.
Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.

Answer: Lysosomes is the answer
Explanation:
Lysosomes are cellular organelles with thin-wall bodies, and serves as sacs containing enzymes that are mainly respiratory in function, thus the enzymes digest substances taken into the cell to generate energy as ATP
Although the dolphin lives in the sea, it is not a fish - it's a mammal.
It makes the most sense if you read it aloud.
