The Earth holds livings things and even the layer has more complex layers in it (Also it's not white) And of course there are no oceans
Answer:
The correct answer would be - D. What causes cancer cells to grow uncontrollably?
Explanation:
A Biologist is a person that studies living organisms and the study of living organisms and their process called biology. Biology is a very vast field that involves many branches such as zoology, botany, biochemistry, immunology, biophysics, anatomy, ecology and many more.
So, given all are can be an example of the study biology wanted to do, however, the question most likely studied by a biologist would be What causes cancer cells to grow uncontrollably as it deals with an organism and their biological process.
the answer is A.) because the scientific method is used to answer problems.
This is the steps,
STEP 1: ask a question
STEP 2: state your hypothesis
STEP 3: conduct an experiment
STEP 4: analyze your results
STEP 5: make a conclusion
Redox reactions are those <u>chemical reactions that involve the transfer of electrons between reactants</u>, altering the <em>oxidation state</em> of their elements.
In this type of reactions an element releases electrons that another element accepts, so there is a net transfer of charge.
When balancing redox reactions, not only must the chemical elements in the reactants and products be equalized (by the <em>law of conservation of the mass</em>), but also the charged that is transferred in the process must be balanced, since <u>the electrons that are lost in oxidation are the same as those that are gained in reduction (</u><em>law of conservation of charge:</em> <em>there is no destruction or net creation of electric charge</em>).
the equation balanced is
3 PbI4 + 4 CrCl3 → 3 PbCl4 + 4 CrI3
