Answer:
Dogs shown in this picture belongs to the secondary consumer trophic level which consumes primary consumer herbivores. These primary consumer herbivores are dependent on grass for food which is a primary producer. If all dogs die, the population of primary consumer herbivores will increase. This increase will lead to decrease in grass at a drastic rate. Therefore, primary producers (grass) will be affected.
A universal genetic code allows "the processes of transcription and translation to produce the same proteins in all species."
To say that the genetic code is universal it means that it is read/interpreted in the same exact way in all cells. This is that the same group of three nucleotides, a codon, will always translate into the same amino acid in any cell leading to the formation of the same protein, or at least a protein with same amino acids when first formed.
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
