Question: Q: What is the name for the division of the cytoplasm in eukaryotic cells, resulting in two genetically identical daughter cells? Read this paragraph and choose the correct option from the provided answers: The second major step is cytokinesis. As in prokaryotic cells, the cytoplasm must divide. Cytokinesis is the division of the cytoplasm in eukaryotic cells, resulting in two genetically identical daughter cells. Choices: - mitosis - vegetative division - metamorphosis - cytokinesis A:
Answer: cytokinesis

Question: Q: The rate at which an unstable isotope decays is measured in a unit known as what? Read this paragraph and choose the correct option from the provided answers: The decay of an unstable isotope to a stable element occurs at a constant rate. This rate is different for each parent-daughter isotope pair. The decay rate is measured in a unit called the half-life. The half-life is the time it takes for half of a given amount of an isotope to decay. For example, the half-life of carbon-14 is 5,730 years. Imagine that you start out with 100 grams of carbon-14. In 5,730 years, half of it decays. This leaves 50 grams of carbon-14. Over the next 5,730 years, half of the remaining amount will decay. Now there are 25 grams of carbon-14. How many grams will there be in another 5,730 years? The figure below graphs the rate of decay of a substance ( Figure below ). Choices: - full-life - staying-life - half-time - half-life A:
Answer: half-life

Question: Q: What type of fish are the majority of living species? Read this paragraph and choose the correct option from the provided answers: Ray-finned fish include the majority of living fish species, including goldfish, tuna, salmon, perch, and cod. They have a bony endoskeleton and a swim bladder. Their thin fins consist of webs of skin over flexible bony rays, or spines. The fins lack muscle, so their movements are controlled by muscles in the body wall. You can compare their ray fins with the fleshy fins of lobe-finned fish in Figure below . Choices: - cartilaginous fish - freshwater fish - lungfish - ray-finned fish A:
Answer:
ray-finned fish
