Because through natural selection, only the fittest survive. when the fittest come together and reproduce then the species continues and evolves with only the fittest and strongest genes.
<span>Mature tRNA has an amino acid binding site at one end and the other end interacts with the mRNA by complementary base pairing due to the presence of an anticodon. An anticodon is a three nucleotide sequence which is complementary to the triplet codon of mRNA which specifies a protein for synthesis.</span>
lemon juice is 100 times as acidic as tomato juice. remember, each step in the pH scale represents a change in concentration by a factor of 10. since tomato juice has a pH of 4.0, and lemon juice has a pH of 2.0, the concentration would change by 10 times 10.
Answer:
Liquids have more kinetic energy than solids
Explanation:
When a substance increases in temp, heat is being added, and its particles are gaining kinetic energy.
Answer:
I.
4) The deoxygenated blood then travels through the veins and enters the right side of the heart.
1) The blood leaves the heart through the aorta.
2) The blood travels throughout the body via the arteries to the capillaries.
3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.
II.
2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.
1) The deoxygenated blood flows from the right side of the heart to go to the lungs.
3) The oxygenated blood then returns to the left side of the heart.
