Which of the following statements about how the organisms in the food chain store carbon is NOT true? The crab expels carbon dioxide into the hydrosphere when glucose is converted into ATP.

The fish ingests carbon dioxide from the hydrosphere and stores the carbon for later use.

The algae uses carbon dioxide to create glucose to be stored for later use.

The crab ingests carbon from the snail and stores the carbon until it is used for energy.

Explain why phospholipid molecules form a bilayer. (3 marks)

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

The hematodinium parasite becomes less of a problem for the blue crab when the crab is very young. fishing is thriving in the region. the crab moves to less salty water. a significant percentage of the population is impacted.
