Paint changes color to the physical eye.
Answer:
They have different amounts of neutrons.
They have different mass numbers.
Explanation:
Carbon-12 and carbon-13 are two isotopes of the element carbon. The difference between carbon-12 and carbon-13 is the number of neutrons in each atom. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-13 contain 7 neutrons. And because the mass number is the sum of protons and neutrons in the nucleus then will be different too. Atoms of carbon-12 have the mass number equal to 12 a.m.u. while atoms of carbon-13 have the mass number equal to 13 a.m.u. .
a.m.u. - atomic mass units
Answer:
Explanation:
When a Newton's Cradle with three marbles is pulled back and released, the mechanical energy is converted to potential elastic energy.
When a collision happens between the marbles causing a cycle of repeated motion, The elastic potential energy is converted to kinetic energy.
This transfer of energy will last for several cycles. If there is any energy lost, then the kinetic energy must have been converted to thermal energy or heat energy
The wt% of KOH = 45%
This implies that there is 45 g of KOH in 100 g of the solution
Density of the solution is given as 1.45 g/ml
Therefore, the volume corresponding to 100 g of the solution is
= 100 g * 1 ml /1.45 g = 68.97 ml = 0.069 L
Now concentration of the concentrated KOH solution is:
Molarity = moles of KOH/vol of solution
= (45 g/56.105 g.mol-1)/0.069 L = 11.6 M
Thus,
Initial KOH concentration M1 = 11.6 M
Initial volume = V1
Final concentration M2 = 1.20 M
Final volume V2 = 250 ml
M1*V1= M2*V2
V1 = M2*V2/M1 = 1.20*250/11.6 = 25.9 ml = 26 ml
A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that form a polypeptide chain during active translation. Since multiple ribosomes can translate mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.
<h3>Role of all molecular constituents present in a functional polyribosome ;</h3>
1. mRNA: contains the codon
2. tRNA : contains the anticodon for the mRNA
3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA
4. Amino acids:
5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence
7. Elongation Factors: bring charged tRNA's to the A site of the ribosome
8. GTP: provides energy
Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that overlapping sequences will be translated.
