Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.
<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:
now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula
Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL
So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
Question 1
Answer:
D- Different nucleotide combinations code for the same amino acid.
Explanation:
Some amino acid has more than one nucleotide combination coding for it.
Question 2
Answer:
B- Redundancy
Explanation:
Redundancy means that more than one codon is assigned for the coding of most amino acids.
Question 3
Answer:
0%
Explanation:
Since both parents are homozygous dominant and recessive respectively, no crossing can give the homozygous dominant as all offspring are heterozygous.
Question 4
Answer:
Homozygous.
Explanation:
The genotype 'dd' is homozygous since the two letters are both in the lower case.
Question 5
Answer:
25%
Question 6
Answer:
Dihybrid cross
Answer:
Static stretching
Explanation:
Autogenic inhibition and reciprocal inhibition occur when Golgi tendon Organ is activated leading to inhibition of certain from contracting.
Stretching is a form of exercise that improves muscle's felt elasticity by deliberately flexing it.
Static Stretch entails singular motion held in a place for ten seconds or more and it is used to increase soft tissue extensibility through both Autogenic and Reciprocal inhibition.
