Q: What are the most advanced group of seedless vascular plants called? Read this paragraph and choose the correct option from the provided answers: The seedless vascular plants include club mosses, which are the most primitive; whisk ferns, which lost leaves and roots by reductive evolution; and horsetails and ferns. Ferns are the most advanced group of seedless vascular plants. They are distinguished by large leaves called fronds and small sporangia-containing structures called sori, which are found on the underside of the fronds. Mosses play an essential role in the balance of the ecosystems; they are pioneering species that colonize bare or devastated environments and make it possible for a succession to occur. They contribute to the enrichment of the soil and provide shelter and nutrients for animals in hostile environments. Mosses and ferns can be used as fuels and serve culinary, medical, and decorative purposes. Choices: - shrubs - conifers - grasses - ferns A:
(Answer)
ferns

Q: How are the number of moles of carbon dioxide gas calculated? Read this paragraph and choose the correct option from the provided answers: The number of moles of carbon dioxide gas is first calculated by stoichiometry. Then the ideal gas law is used to calculate the volume of CO 2 produced. Choices: - relativistic - casuistry - phytochemistry - stoichiometry A:
(A).
stoichiometry

Ques:Q: What does the megaspore mother cell produce after meiosis division? Read this paragraph and choose the correct option from the provided answers: Watch this video (http://openstaxcollege. org/l/pollen_release) to see a cedar releasing its pollen in the wind. Female Gametophyte The female cone also has a central axis on which bracts known as megasporophylls (Figure 32.10) are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium. Choices: - four diploid megaspores - two diploid megapores - two haploid megaspores - four haploid megaspores A:

Ans:four haploid megaspores

Read this paragraph and choose the correct option from the provided answers: The cell cycle is a repeating series of events, characterizing the life of a eukaryotic cell. Choices: - only divide cells - create new cells - only reproduce cells - divide and reproduce cells A:

Ans:
