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 river forms from water moving from a higher elevation to a lower elevation, all due to gravity. Flowing water finds its way down a slope initially as small creeks. As small creeks flow downhill they shape larger streams and rivers. Rivers eventually end up flowing into the oceans with much more speed than was originally there.
Hope it helps and I did it correctly and used that words I needed to.
Answer:
Genes is not the only factor in determining the characteristics of an organism environment is also a major factor.
Explanation:
- The organisms having the traits which are very favorable or suited in an environment have greater probability of surviving and reproducing at the higher rate than any organism which are less suited to that environment.
- When an organism start developing from one stage to another, the interaction of genes with the environment initiates at every moment of its life.
- The interaction of genes and environment determines the characteristics of that organism.
