Answer:
D
Explanation:
A, B and C are incorrect since the greater the pH value, the more alkaline a solution is, and the pH of water is 7.
In the statement D, the pH of NaOH solution is 13 usually, so the given solution is less alkaline than NaOH solution, and I think of the same concentration is somewhat unnecessary.
<span>At a depth of 34 feet the diver experiences 2 atmospheres of pressure.
At a depth of 68 feet the diver is experiencing 3 atmospheres.
At a depth of 102 feet the diver is experiencing 4 atmospheres of pressure.
At one atmosphere of pressure the body is mildy compressed. As the diver descends the divers body will undergo increased compression instead of being squashed.</span>
Its relative density causes objects to float or sink.
If the density of the substance is greater than the substance it is in, it will sink.
If the density is less than the substance it is in it will float.
Explanation:
Not only did outermost electron determine the valence electron, but also <em>periodic</em><em> </em><em>table</em><em>.</em><em> </em>whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron
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.
