Answer:
C
Explanation:
These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.
Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.
We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.
I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
True. because this is the answer
The answer is c radius because for example birds that have wings is a example of analogue structures in animals
Answer:
A. 15%
Explanation:
DNA is composed of four nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Chargaff's rule of base pairing states that A always pairs with T, while G always pairs with C. The total distributed percentage of the four 4 nitrogen bases must be equal to 100%. In this case, the C content is 35%, thereby G=35% (i.e., equal to C content), while the remaining 30% must be equally divided between T=15% and A=15%.
Answer: option E) ) the pond is now pH neutral and it has more hydrogen ions than at pH 7.5
Explanation:
A pH reading of 7.0 is said to be neutral, so the pond after the chemical treatment is neutral in pH.
Also, the pond now has more hydrogen ions than at pH 7.5, because
- a pH value of 7.5 is slightly more alkaline than a pH value of 7.0; and the lower the pH value of the pond, the higher the hydrogen ions concentration viz a viz
Thus, at pH 7.0 there are more hydrogen ions than at pH 7.5.
