Answer:
Hello!
The answer is C) substitution
Explanation:
Substitution:
A kind of mutation that involves the substitution of a single nucleotide by another, without changing the frame of reference of the DNA sequence. In this particular example, the thymine in the codon GAG (codes for glutamic acid) is being substituted by the base adenine, leaving the codon GTG (codes for the amino acid, valine).
The described substitution occurs in the case of the disease, sickle cell anemia that yields abnormal heamoglobin.
- A) A deletion removes a base from the DNA sequence. This alters the frame of reference of the mRNA.
- B) An insertion involves the addition of a base into the DNA sequence.
- D) A silent mutation substitutes a base in such as way that the new codon codes for the same amino acid, conserving the function and structure of the protein; therefore, silent mutations are harmless.
Solar energy is more Natural since it comes from the sun and easier to harness, while chemical energy is Dangerous because it may fail and cause damage.
Answer:
2)Herbivores and carnivores
Explanation:
Because it feeds on small animals and plants.
Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency
