Pollution can effect the food chain and the food web In many ways. The first of wich is it can kill off animals. A good example of this is marine life.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
Answer:
step 1: mRNA attaches to the ribosome
step 2: tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids
step 3: tRNA carries its specific amino acid to the ribosome
step 4: tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA
step 5: Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond
step 6: Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain
Answer:
B. CO2 out
Explanation:
The excretion is the process of removal of the waste product from the body. The carbon dioxide is the byproduct of the aerobic respiration, which is carries from the tissues and the lungs by blood. In the lungs at alveoli, the carbon dioxide is transferred from the blood to the lungs and released out through the nostrils. Hence, the out of the carbon dioxide represent excretion through lungs.
In cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. In stage one glucose is broken down in the cytoplasm of the cell in a process call glycolysis. In stage two the pyruvate molecules are transported into the mitochondria
