Answer:
5 bases
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases 
is 16 and it is not enough combination for all 17 amino acids
for 5 bases 
is 25 combinations (meaning that more than one codon could code for the same amino acid).
Answer:
A negative charge exists because of the electronegativity of oxygen. A polar water molecule is made up of hydrogen and oxygen. Due to its atomic structure, there is an unequal distribution of charges and thus oxygen gets a more negative charge while hydrogen gets a positive charge.
Explanation:

Answer:
The mass of salt water is 390 grams
Explanation:
To calculate the mass of salt water, we use the equation:
\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}Density of substance=
Volume of substance
Mass of substance
Density of salt water = 1.30g/cm^31.30g/cm
3
Volume of salt water = 300 mL = 300cm^3300cm
3
(Conversion factor: 1mL=1cm^31mL=1cm
3
)
Putting values in above equation, we get:
\begin{gathered}1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3\times 300cm^3)=390g\end{gathered}
1.30g/cm
3
=
300cm

Mass of salt water
Mass of salt water=(1.30g/cm

Hence, the mass of salt water is 390 grams
Answer:
Attracting prey
Explanation:
Rule out other answers.
Plants in dark water already are adapted.
If a fish such as an angler fish lives in dark waters then there would not be a need to create light to see because then they could just live in a different part of the ocean.
Light doesn't create oxygen.
