Q: How do most fish reproduce with one another? Read this paragraph and choose the correct option from the provided answers: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. Choices: - on land - asexually - same sex - sexually A:
sexually

Q: The process where an atomic nucleus breaks apart into two less massive nuclei is known as ______. Read this paragraph and choose the correct option from the provided answers: Fission is the process in which an atomic nucleus breaks apart into two less massive nuclei. Energy is released in the process in many forms, heat, gamma rays and the kinetic energy of neutrons. If these neutrons collide with nuclei and induce more fission, then a runaway chain reaction can take place. Fission is responsible for nuclear energy and atom-bomb explosions: the fission of uranium acts as a heat source for the Earth's molten interior. Choices: - diffusion - fusion - collision - fission A:
fission

Q: Thylakoid membranes contain molecules of what green pigment used in photosynthesis? Read this paragraph and choose the correct option from the provided answers: The structure of a chloroplast shows how membrane and molecular architecture helps life processes. A chloroplast consists of thylakoid membranes surrounded by stroma. The thylakoids stack on top of each other, like a stack of pancakes. The thylakoid stacks arrange chlorophyll, accessory pigment molecules, and photosynthetic proteins to capture sunlight and allow a concentration of ions within the sacs. You can see the green color of the chlorophyll. You cannot see the electron carriers, sequenced within the sac membranes, but their arrangement helps harvest small amounts of energy from excited electrons. The thylakoid membranes contain molecules of the green pigment chlorophyll. Choices: - carbonate - sodium - copper - chlorophyll A:
chlorophyll

Q: What is the movement of animals from one place to another called? Read this paragraph and choose the correct option from the provided answers: Migration is the movement of animals from one place to another. Migration is most common in birds, fish, and insects. In the Northern Hemisphere, many species of birds, such as finches and swallows, travel south for the winter. They migrate to areas where it is warmer and where more food is available. They return north in the spring. Migrating animals generally follow the same route each year. They may be guided by the position of the sun, Earth's magnetic field, or other clues in the environment. Choices: - evacuation - hibernation - extinction - migration A:
migration
