Star brightness is defined by either <span>D. apparent magnitude - when we measure it from Earth (that is how bright it is from Earth) - this is the closest to "basic observation" and the best answer
or by absolute magnitute - how bright it would be at a certain distance (this allows to compare the brightness).

Answer:
A native-species
Explanation:
A native-species is one that normally lives and thrives in a particular ecosystem. They are any species that developed within the surrounding habitat.
They are usually found in an ecosystem because of natural processes like evolution or natural selection. They are known to occur naturally within a given habitat as opposed to species that are introduced.
The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.
Answer:
The change in PH not only effect the shape of enzymes, but it may also change properties the of substrate so that that substrate cannot control to bind the active site and it cannot undergo catalysis.
In general enzymes have a PH optimum. However this optimum is not same for each enzyme.
Explanation:
For Example; The enzyme pepsin is most active at an acidic PH, Whereas the enzyme trypsin performs best at slightly alkaline PH. the increase or decrease in PH can change the concentration of ion in a solution
