The following are some of the questions and answers for the biology examination paper of Luzhou City, Sichuan Province in 2023: - ** 1. Multiple choice questions ** - [Question 1: Answer B] Reed is a plant, and the energy convertors in plant cells are chlouroplasts and mitochondria. Pufferfish is an animal, and the energy convertors in animal cells are mitochondria, so A is wrong; during the process of bud sprouting, the number of cells increases through cell division, B is correct; the swimming behavior of pufferfish is controlled by the brain, which is mainly composed of nerve tissue, C is wrong; The structure level of reed is cell → tissue → organ → individual, and the structure level of pufferfish is cell → tissue → organ → system → individual, D is wrong. - [Question 2: Answer A] Mulberry trees, silkworms, fish, and other creatures, together with the environment they live in, form a complete ecosystem. A is wrong; mulberry trees can carry out photosynthesis to produce organic matter by themselves and are producers in the ecosystem. B is correct; In this ecosystem, the energy needed for silkworm life activities ultimately comes from solar energy (fixed through mulberry trees 'photosynthesis). C is correct; Mulberry fish ponds turn silkworm manure from waste into fish feed, turning waste into treasure. D is correct. - [Question 3: Answer C] The center of the hand-retracting reflex was the spinal cord, and the pain sensation was formed in the brain. C was correct. - [Question 4: Answer C] The flu virus cannot live independently and must be parasitic in living cells. A is wrong.
