Q: What kind of organisms are yeasts? Read this paragraph and choose the correct option from the provided answers: The aim of basic science is to discover new knowledge. It leads to a better understanding of the natural world. It doesn't necessarily have any practical use. An example of basic research in life science is studying how yeast cells grow and divide. Yeasts are single-celled organisms that are easy to study. By studying yeast cells, life scientists discovered the series of events called the cell cycle. The cell cycle works not only in yeasts but in all other organisms with similar cells. Therefore, this basic research made a major contribution to our understanding of living things. Watch the following animation to learn more about the basic yeast research and the cell cycle. You can also see yeast cells dividing. Choices: - bacteria - viruses - protozoa - single-celled A:
(Answer)
single-celled

Q: What is made and stored primarily in the cells of the liver and muscles? Read this paragraph and choose the correct option from the provided answers: Glycogen is an even more highly branched polysaccharide of glucose monomers that serves a function of energy storage in animals. Glycogen is made and stored primarily in the cells of the liver and muscles. Choices: - glucose - carbon dioxide - oxygen - glycogen A:
(Answer)
glycogen

Q: In which kind of animals does parthenogenesis occur? Read this paragraph and choose the correct option from the provided answers: Note that in fragmentation, there is generally a noticeable difference in the size of the individuals, whereas in fission, two individuals of approximate size are formed. Parthenogenesis Parthenogenesis is a form of asexual reproduction where an egg develops into a complete individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process and the species. Parthenogenesis occurs in invertebrates such as water flees, rotifers, aphids, stick insects, some ants, wasps, and bees. Bees use parthenogenesis to produce haploid males (drones) and diploid females (workers). If an egg is fertilized, a queen is produced. The queen bee controls the reproduction of the hive bees to regulate the type of bee produced. Some vertebrate animalssuch as certain reptiles, amphibians, and fishalso reproduce through parthenogenesis. Although more common in plants, parthenogenesis has been observed in animal species that were segregated by sex in terrestrial or marine zoos. Two female Komodo dragons, a hammerhead shark, and a blacktop shark have produced parthenogenic young when the females have been isolated from males. Choices: - tissues - mammals - species - invertebrates A:
(Answer)
invertebrates
