How would u approach the first one, #54
Take a clearer picture and upload and I’ll see if I can help ♥️
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
The average radius of a molecule of Iysozyme, an enzyme in tears, is 1430 pm.
The size of an element's nucleus and also the total number of electrons around it grow with an element's atomic number. The radius of an atom increases with increasing atomic number.
The calculation of conversion of radius is shown below:
It is known that, 1 meter is equal to 10¹² picometers.
We can use a conversion fraction to convert 1430 picometers to meters.
1430 pm × (1 m / 10¹² pm) = 1.430 × 10⁻⁹ m
1 meter is equal to 10⁹ nanometers.
Now, use a conversion fraction to convert 1.430 × 10⁻⁹ meters to nanometers.
1.430 × 10⁻⁹ m × (10⁹ nm/1 m) = 1.430 nm
Therefore, the radius of nanometers will be 1.430nm

This is possible because when a star dies, it basically expands to its maximum (explodes). Therefore, the materials of the exploded star mix with the primeval hydrogen of the Universe. Later, other stars are formed out of this mixture. Thats also how the sun was formed. :)
