Answer the following question given this paragraph: A molecular formula of the compound carbon dioxide is CO 2 . One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen. We can calculate the mass of one molecule of carbon dioxide by adding together the masses of 1 atom of carbon and 2 atoms of oxygen. Q: One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of what element? Choices: - methane - hydrogen - nitrogen - oxygen A:
oxygen

Answer the following question given this paragraph: Like bacteria, reproduction in archaea is asexual. Archaea can reproduce through binary fission , where a parent cell divides into two genetically identical daughter cells. Archaea can also reproduce asexually through budding and fragmentation, where pieces of the cell break off and form a new cell, also producing genetically identical organisms. Q: Pieces of the cell break off and form a new cell in what type of reproduction that produces genetically identical organisms? Choices: - Meiosis - Mitosis - Fusion - fragmentation A:
fragmentation

Answer the following question given this paragraph: There is a second distinction between the types of cleavage in protostomes and deuterostomes. In addition to spiral cleavage, protostomes also undergo determinate cleavage. This means that even at this early stage, the developmental fate of each embryonic cell is already determined. A cell does not have the ability to develop into any cell type. In contrast, deuterostomes undergo indeterminate cleavage, in which cells are not yet pre-determined at this early stage to develop into specific cell types. These cells are referred to as undifferentiated cells. This characteristic of deuterostomes is reflected in the existence of familiar embryonic stem cells, which have the ability to develop into any cell type until their fate is programmed at a later developmental stage. Q: In addition to spiral cleavage, protostomes also undergo which other form of cleavage? Choices: - straight - diagonal - dispersive - determinate A:
determinate
