Answer:
1.99metres
Explanation:
Foot and inches are measurements of heights. A height measurement of 6’6 1/2" means I am 6 foot and 6.5 inches tall.
Firstly, we need to convert the foot and inches measurement to all foot.
Since 1 foot = 12 inches
Then, the 6.5 inches is 6.5/12
= 0.5416foot
We add this to the existing feet measurement, i.e. 6 foot + 0.5416 foot
= 6.5416 foot.
Hence, 6'6.5" means 6.5416'
Now, we convert the foot measurement to metres.
1 foot makes 30.48 cm
Since 100 cm makes 1 m
30.48 cm will be 30.48/100= 0.3048m
Hence, 1 foot = 0.3048m
6.5416 foot = 6.5416 × 0.3048 m
= 1.9938
Therefore, a height measurement of 6’6 1/2" is 1.99 metres tall.
Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
Independent Variable: Scenarios (such as different times of the day or places) used to check if a person will become depressed or not.
Dependent Variable: Number of people diagnosed with depression.
Constant: Amount of people who do not understand depression.
Control: How your setting can impact mood and performance.
