Answer:
Diffusion rate is 1.96 × 
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 
r = 
= 
= 7.5 mm = 0.75 cm
area = 
× 
= 1.7679
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643 /s
Diffusion rate is 1.96 × /s
Explanation:
main difference between competitive and noncompetitive inhibition is that competitive inhibition is the binding of the inhibitor to the active site of the enzyme whereas noncompetitive inhibition is the binding of the inhibitor to the enzyme at a point other than the active site.
Answer:
The null hypothesis is a general statement that states that there
is no relationship between two phenomenons under
consideration or that there is no association between two groups.
A hypothesis, in general, is an assumption that is yet to be proved
with sufficient pieces of evidence.
Answer:
The correct answer is -
1. Adenine - 10%
2. A-T and C-G always in DNA.
Explanation:
1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.
So, Cytosine = 40%, Guanine= 40%
total = 80%
therefore, the A and thymine would be - 100 - 80 = 20
A+T = 20
A= 10, and, T = 10%
2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.
