Question: Answer the following question given this paragraph:   Archaeplastida Red algae and green algae are included in the supergroup Archaeplastida. It was from a common ancestor of these protists that the land plants evolved, since their closest relatives are found in this group. Molecular evidence supports that all Archaeplastida are descendents of an endosymbiotic relationship between a heterotrophic protist and a cyanobacterium. The red and green algae include unicellular, multicellular, and colonial forms. Red Algae Red algae, or rhodophytes, are primarily multicellular, lack flagella, and range in size from microscopic, unicellular protists to large, multicellular forms grouped into the informal seaweed category. The red algae life cycle is an alternation of generations. Some species of red algae contain phycoerythrins, photosynthetic accessory pigments that are red in color and.   Q: In which supergroup are red algae and green algae included?   Choices:  - xerophyte  - spirogyra  - troglodyte  - archaeplastida  A:
archaeplastida

Answer the following question given this paragraph:   Chapter 26 1 Figure 26.8 B. The diploid zygote forms after the pollen tube has finished forming, so that the male generative nuclei can fuse with the female gametophyte. 3 D 5 C 7 A 9 B 11 C 13 B 15 C 17 D 19 Both pollination and herbivory contributed to diversity, with plants needing to attract some insects and repel others. 21 The trees are adapted to arid weather, and do not lose as much water due to transpiration as non-conifers. 23 The resemblance between cycads and palm trees is only superficial. Cycads are gymnosperms and do not bear flowers or fruit. Cycads produce cones: large, female cones that produce naked seeds, and smaller male cones on separate plants. Palms do not. 25 Using animal pollinators promotes cross-pollination and increases genetic diversity. The odds that the pollen will reach another flower are greatly increased compared with the randomness of wind pollination.   Q: When does the diploid zygote form?   Choices:  - never  - before the pollen tube  - before the haploid zygote  - after the pollen tube  A:
after the pollen tube

Answer the following question given this paragraph:   The brown color is from nitrogen dioxide gas. Nitrogen dioxide is a byproduct from the combustion of fossil fuels like coal and gasoline.   Q: What is a byproduct from the combustion of fossil fuels like coal and gasoline?   Choices:  - alcohol  - carbon monoxide  - aluminum oxide  - nitrogen dioxide  A:
nitrogen dioxide

Answer the following question given this paragraph:   Find the microwave in the Figure above . A microwave is an electromagnetic wave with a relatively long wavelength and low frequency. Microwaves are often classified as radio waves, but they have higher frequencies than other radio waves. With higher frequencies, they also have more energy. That’s why microwaves are useful for heating food in microwave ovens. Microwaves have other important uses as well, including cell phone transmissions and radar. These uses are described below. You can learn more about microwaves and their uses in the video at this URL: http://www. youtube. com/watch?v=YgQQb1BVnu8 .   Q: Why do microwaves have a higher energy than radio waves?   Choices:  - higher resonance  - lower frequency  - higher decibel  - higher frequency  A:

Answer: higher frequency
