Think about the article. How are Antarctic toothfish and other notothenioids different?

Which of the following is a pseudogene?Multiple choice question.The genes for icefish gill structureThe hemoglobin gene in humansThe genes for human eye colorThe hemoglobin gene in the icefish

Which of the following accurately describes the genes for hemoglobin in icefish that inhabit very cold Antarctic waters?Multiple choice question.The hemoglobin gene appears to have been deleted from their genome, so they can't produce it and have colorless blood.They have a hemoglobin gene which has many mutations, so they do not produce functional hemoglobin and have colorless blood.They have a hemoglobin gene with many mutations which directs the production of functional colorless hemoglobin making their blood also colorless.

Which statement most directly supports the claim that different species of organisms use different metabolic strategies to meet their energy requirements for growth, reproduction, and homeostasis?A. Bacteria lack introns, while many eukaryotic genes contain many of these intervening sequences.B. Carnivores have more teeth that are specialized for ripping food, while herbivores have more teeth specialized for grinding food.C. During cold periods, pond-dwelling animals can increase the number of unsaturated fatty acids in their cell membrances, while some plants make antifreeze proteins to prevent ice crystal formation in their tissue.D. Plants generally use startch molecules for storage, while animals use glycogen and fats for storage.
