A hormone is a molecule that functions as a chemical signal. A hormone is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Endocrine hormone molecules are secreted (released) directly into the bloodstream. !

4y=12

Dividing 4 both sides

y=3

Division property should be used.

Option 2.

2(4y)=12

Opening bracktet in LHS

8y=12

Dividing both sides by 8 i.e.

y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}

Division property is used.

Option 4.

y+4=12

Subtracting both sides by 4 i.e.

Y+4-4=12-4

y=8

Subtraction property is used.

why is it a good idea for a bacterial cell to be abel to use glucose first as an energy source then switch to lactose
olchik [2.2K]

Answer:

Due to less steps and requires less energy.

Explanation:

The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.
