Ascientist hypothesizes that the lack of chinook salmon is negatively affecting the orca population. would this hypothesis need to be tested by another scientist in order to become a theory? why or why not?

Yes

Even if there is an abundance of fish in the oceans, and that even if the general rule is that big things eat smaller things, it is not true with the orca population (whales).  Whales depend on chinook salmon for survival, and truly, the hypothesis that the lack of chinook salmon negatively affecting the orca population is true.

However, for a hypothesis to become lifted to the ranks of a theory once it passes a series of tests. Other scientists may claim its correctness, other may oppose to it.  So there is a need to differentiate between the hypothesis on checking and competing hypotheses.

i think that it is plants

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
