Answer:
c lower oxygen levels

the higher up the person is the closer to the atmosphere so there is less oxygen
3 bases make up the code for amino acids
Answer:
The gene for beta-galactosidase turns off.
Explanation:
The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.
Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.
If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).
Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun.
Answer:
Hi there, the answer is energy
Explanation:
Carbon dioxide, oxygen, and water are all products of cellular respiration in fact carbon dioxide and oxygen are extremely important for ATP. If you are talking about aerobic respiration oxygen is the main product for it because it reacts to glucose. The only thing that isnt part of the product of cellular respiration is energy. After ATP is created for the plants it makes its own energy afterward.
Hope this helped :)
