Answer the following question given this paragraph: Q: Data from paleontology offer insights into the early evolution of what? Choices: - cells - acids - neurons - fungi A:
fungi
Answer the following question given this paragraph: Medulla The medulla is the region known as the myelencephalon in the embryonic brain. The initial portion of the name, "myel," refers to the significant white matter found in this regionespecially on its exterior, which is continuous with the white. Q: What is the region known as the myelencephalon in the embryonic brain? Choices: - Telencephalon - Mesencephalon - Diencephalon - medulla A:
medulla
Q: Answer the following question given this paragraph: During a thunderstorm, some parts of a thunderhead become negatively charged. Other parts become positively charged. The difference in charge creates lightning. Lightning is a huge release of electricity. Lightning can jump between oppositely charged parts of the same cloud, between one cloud and another, or between a cloud and the ground. You can see lightning in Figure below . Lightning blasts the air with energy. The air heats and expands so quickly that it explodes. This creates the loud sound of thunder . Q: What causes lightning during a thunderstorm? Choices: - difference in wind - difference in elevation - difference in temperature - difference in charge A:
A: difference in charge
Question: Answer the following question given this paragraph: Eukaryotes evolved about 2 billion years ago. Unlike prokaryotes, eukaryotes have a cell nucleus. They have more structures and are better organized. Organelles within a eukaryote can perform certain functions. Some supply energy; some break down wastes. Eukaryotes were better able to live and so became the dominant life form. Q: Unlike prokaryotes, eukaryotes have what? Choices: - cell membrane - golgi apparatus - cell wall - cell nucleus A:
Answer: cell nucleus

(Q).
Answer the following question given this paragraph: groups of angiosperms: the monocots and the eudicots. Seed food reserves are stored outside the embryo, in the form of complex carbohydrates, lipids or proteins. The cotyledons serve as conduits to transmit the broken-down food reserves from their storage site inside the seed to the developing embryo. The seed consists of a toughened layer of integuments forming the coat, the endosperm with food reserves, and at the center, the well-protected embryo. Most flowers are monoecious or bisexual, which means that they carry both stamens and carpels; only a few species selfpollinate. Monoecious flowers are also known as "perfect" flowers because they contain both types of sex organs (Figure 26.14). Both anatomical and environmental barriers promote cross-pollination mediated by a physical agent (wind or water), or an animal, such as an insect or bird. Cross-pollination increases genetic diversity in a species. Q: Monoecious flowers are also known as "perfect" flowers because they contain both types of what organ? Choices: - vascular organ - respiratory organ - phloem - sex organ A:
(A).
sex organ
