Answer the following question given this paragraph: The most basic division is between nonvascular plants and vascular plants . Vascular plants are further divided into those that reproduce without seeds and those that reproduce with seeds. Seed plants, in turn, are divided into those that produce seeds in cones and those that produce seeds in the ovaries of flowers. Seed plants are called gymnosperms . Seed plants called angiosperms produce seeds in the ovaries of flowers . Q: What is another word for seed plants? Choices: - protosperm - phyla - echinoderm - gymnosperm A:
gymnosperm

Answer the following question given this paragraph: Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few offspring, allele frequencies in the offspring may differ, by chance, from allele frequencies in the parents. Q: What is the term for a random change in allele frequencies that occurs in a small population? Choices: - evolution - speciation - mutation - genetic drift A:
(Answer)
genetic drift
Ques: Answer the following question given this paragraph: Aquatic species generally have external fertilization, whereas terrestrial species usually have internal fertilization. Q: What process tends to be external in aquatic species and internal in terrestrial species? Choices: - infection - pollination - migration - fertilization A:
Ans: fertilization

Answer the following question given this paragraph: Alkenes Organic compounds that contain one or more double or triple bonds between carbon atoms are described as unsaturated. You have likely heard of unsaturated fats. These are complex organic molecules with long chains of carbon atoms, which contain at least one double bond between carbon atoms. Unsaturated hydrocarbon molecules that contain one or more double bonds are called alkenes. Carbon atoms linked by a double bond are bound together by two bonds, one bond and one bond. Double and triple bonds give rise to a different geometry around the carbon atom that participates in them, leading to important differences in molecular shape and properties. The differing geometries are responsible for the different properties of unsaturated versus saturated fats. Ethene, C2H4, is the simplest alkene. Each carbon atom in ethene, commonly called ethylene, has a trigonal planar structure. The second member of the series is propene (propylene) (Figure 20.7); the butene isomers follow in the series. Four carbon atoms in the chain of butene allows for the formation of isomers based on the position of the double bond, as well as a new form of isomerism. Q: What are alkenes organic compounds that contain one or more double or triple bonds between carbon atoms described as? Choices: - saturated - insulated - strong - unsaturated A:
(A).
unsaturated
Ques:Answer the following question given this paragraph: Biochemical reactions are chemical reactions that take place inside the cells of organisms. Q: Where do biochemical reactions take place? Choices: - between cells - in atoms - outside of cells - inside the organisms' cells A:

Ans:inside the organisms' cells
Answer the following question given this paragraph: Geysers are also created by water that is heated beneath the Earth's surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser . Q: Geysers are created when what is heated beneath the earth's surface? Choices: - magma - gases - air - water A:
water
