43. A plant has a double mutation: ctr (constitutive triple response, meaning it always shows the triple response regardless of ethylene) and ein (ethylene insensitive, meaning it cannot respond to ethylene). What would be its triple-response phenotype?(A) It would display a normal triple response, as the mutations compensate for each other.(B) It would not display the triple response, as the ein mutation makes it insensitive to ethylene.(C) It would constitutively display the triple response, because the ctr mutation is dominant.(D) Its phenotype would be intermediate between a wild-type plant and a ctr mutant.

46. Ruminant animals, such as cows, have specialized digestive systems that allow them to obtain significant nutrients from cellulose-rich plant material. Which of the following best describes the key adaptation responsible for this ability?(A) They have an extended small intestine for increased absorption surface area.(B) Their stomach has four chambers, with mutualistic microorganisms digesting cellulose in the rumen and reticulum.(C) They produce unique enzymes in their abomasum that directly break down cellulose.(D) They re-ingest their feces to re-process undigested plant matter, similar to coprophagous animals.
