Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.

The presence of some water body like oceans, seas, or large lake in an area affects the climate such that it moderates the weather so that highs and lows are less extreme.
Climate is a type of weather that remains in an area for a very long-time. A specific kind of weather is the identity of any area and is called climate. In general, the average time period for a climate to remain the same of over 30 years.
Weather is the short term condition of any smaller area that can change at any instant. It can be of different varieties like cloudy, windy, rainy, dry, etc. Th presence of water bodies affects the weather because the water allows a region to cool down to heat up quickly.

Answer:
D. Cellular respiration releases oxygen and photosynthesis releases carbon dioxide
Answer:
Pons.
Explanation:
Inside of our brainstem, there is a structure which is called the pons, which is present besides the medulla oblongata. The pons is a significant structure in the upper part of our brainstem. It controls breathing, communication between different parts of the brain, and as well as sensations such as hearing, taste, and balance.
Pons is that part of the brainstem which carries one-way communications that advise the cerebellum of voluntary motor activities initiated by the motor cortex.
