It is 19.3g/cm^3. To find density, you divide mass by volume, or d=m/v
Answer: Your guess is right
Explanation: Other reactions release energy, so forming sucrose from glucose and fructose is endoergic. Also a water molecule is formed.
When two molecules form new molecule, order is increased and energy is needed that. IT could also possible to use standard energies of formation.
Answer:
Forethought
Explanation: Basically means planning ahead of time in order to know what to do when you are faced in a situation or event that will happen in the future
Answer:
A,B and E
Explanation:
- I+: I refers to the lac repressor, the + indicates that the repressor is functional
- P+: P refers to the promoter region and the + indicates that the promoter is functional
- Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
- Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
- Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional
So based on the breakdown above:
- C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.
- D is not true because Z-, no β-galactosidase is produced.
Only A, B and E apply.
Since 1910, the urban population has grown by nearly 500 percent while the rural population has grown by 19 percent. ... The Census Bureau estimates that during the same 30-year period, the population of the 49 states grew by more than 82 million people, or 36 percent
