Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics
Explanation:
A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.
When mutation occurs in a cell, for the mutation to affect the traits expressed by the particular cell, it must follow this sequence directly:
A change in the sequence of DNA bases--> Joining amino acids in the sequence --> Appearance of characteristics.
Answer:
The fourth one down
Explanation:
It is the only setup in which the units of "cm" and "in" cancel correctly and give the desired units of "ft."
The second one down has the correct units but the wrong conversion factor for converting centimetres to inches.
Conc = moles / Vol you have C but need to find moles
moles KCl = mass / molar mass
25 g / 74.55 g,p;
0.335 moles
So rearrange the formula to find volume. Vol = moles / Conc
0.335 moles / 0.750 mol / L = 0.447 L or 447 mL
The answer in this question is 447 mL.
Answer:
131 K
Explanation:
The only variables are volume and temperature, so we can use Charles' Law:
V1/T1 = V2/T2
Data:
V1 = 2.00 L; T1 = 210 K
V2 = 1.25 L; T2 = ?
Calculation:
2.00/210 = 1.25/T2
Multiply each side by the lowest common denominator (210T2)
2.00T2 = 1.25 ×210
2.00T2 = 262.5
T2 = 262.5/2.00 = 131 K
The gas was cooled to 131 K.
Answer: a.KOH
Potassium hydroxide is an ionic compound where the K+ is the cation and OH−is the anion. At the same time, the compound also contains a covalent bond since the anion, OH−is formed from electron sharing between the O and H atoms.
