The correct answer is - C. Strains of bacteria can become immune to antibiotics that once killed them effectively.

One of the best examples where we can witness the evolution taking place are the bacteria. The bacteria can be very dangerous, so because of that people created antibiotics in order to control it or destroy it. But the bacteria has shown on multiple occasions that it actually is able to develop immunity to the antibiotics after few generations. Because of that, new antibiotics are constantly made in order to cope with the bacteria, but it constantly manages to strengthen its immune system, so its an ever going battle between the evolution of the bacteria and the scientists that try to kill it.

Answer:

Since, the original DNA sequence has not been provided, the mutation can be an insertion/deletion or a frameshift mutation.

  1. Mutated DNA
  2. Frameshift mutation/ insertion or deletion
  3. All the amino acids  changed after the  point mutation​

Explanation:

Frameshift Mutation:

  • A frameshift mutation is the alteration in the reading frame of the DNA due to the addition/deletion of one or two nucleotides.
  • This type of mutation moves the mRNA sequence one or two bases forwards or backwards which disrupts the three base codons sequence required for translation into proteins.
  • The CT at the end of the sequence is indicative of a frameshift in the DNA reading frame.
  • Frameshift mutation affect all amino acids in a polypeptide chain as all codons are moved one or two steps forwards or backwards.

Lights is produced by the_____ force
Dmitrij [34]

Answer:

The electromagnetic force is responsible for generating visible light as well as radiation in other wavebands not detectable by the human eye. As electrons and protons fly around bumping into each other in a light source, the electromagnetic force produces photons of all wavelengths across the electromagnetic spectrum.

Leya [2.2K]

Answer:

The correct answer is - 50%

Explanation:

In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:

      R     W

R    RR   RW

W   RW    WW

here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
