Q: When plant type alternates from generation to generation what is this called? Read this paragraph and choose the correct option from the provided answers: Plants alternate between diploid-cell plants and haploid-cell plants. This is called alternation of generations , because the plant type alternates from generation to generation. In alternation of generations, the plant alternates between a sporophyte that has diploid cells and a gametophyte that has haploid cells. Choices: - turbidity of generation - differentiation of generation - change in generation - alternation of generation A:
alternation of generation

Q: What is the term for a structure within the cytoplasm that performs a specific job in the cell? Read this paragraph and choose the correct option from the provided answers: Eukaryotic cells also contain other organelles besides the nucleus. An organelle is a structure within the cytoplasm that performs a specific job in the cell. Organelles called mitochondria, for example, provide energy to the cell, and organelles called vacuoles store substances in the cell. Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Choices: - mitochondria - nucleus - ribosome - organelle A:
organelle

Q: After what life stage does the fusion inside a star end? Read this paragraph and choose the correct option from the provided answers: After a star becomes a red giant, it will take one of several different paths to end its life. Which path is followed by a star after the red giant phase depends on its mass. During the fusion life of a star, its size is the result of a competition between fusion heat pushing the material out and gravity pulling the material in. At the end, gravity always wins. After the star has lived through its red giant stage, the fusion essentially ends (the star runs out of fuel) allowing gravity to collapse the star. Some of the outer layers of material will be blown away and the core becomes smaller and denser. The core will become either a neutron star, a white dwarf, a black dwarf, or a black hole. Choices: - blue giant - yellow dwarf - white dwarf - red giant A:
red giant

Q: Differences between organisms reflect differences between their nucleotide sequences rather than between their what? Read this paragraph and choose the correct option from the provided answers: Choices: - molecular codes - amino acids - environments - genetic codes A:
genetic codes
