Q: The wavelength of a wave is the distance between corresponding points on what? Read this paragraph and choose the correct option from the provided answers: Q: The wavelength of a wave is the distance between corresponding points on adjacent waves. For example, it is the distance between two adjacent crests in the transverse waves in the diagram. Infer how wave frequency is related to wavelength. Choices: - distant waves - spectrum - basic waves - adjacent waves A:
adjacent waves

Q: What are the main organs of the respiratory system? Read this paragraph and choose the correct option from the provided answers: The lungs are the main organs of the respiratory system. This is where gases are exchanged between the air and the blood. Gases are also transported by the blood and exchanged between the blood and all the cells of the body. Choices: - ovaries - intestines - kidneys - lungs A:
(Answer)
lungs

Ques: Q: What type of plant is the dominant group of land plants? Read this paragraph and choose the correct option from the provided answers: Vascular Plants The vascular plants are the dominant and most conspicuous group of land plants. There are about 275,000 species of vascular plants, which represent more than 90 percent of Earth's vegetation. Several evolutionary innovations explain their success and their spread to so many habitats. Vascular Tissue: Xylem and Phloem The first fossils that show the presence of vascular tissue are dated to the Silurian period, about 430 million years ago. The simplest arrangement of conductive cells shows a pattern of xylem at the center surrounded by phloem. Xylem is the tissue responsible for long-distance transport of water and minerals, the transfer of water-soluble growth factors from the organs of synthesis to the target organs, and storage of water and nutrients. A second type of vascular tissue is phloem, which transports sugars, proteins, and other solutes through the plant. Phloem cells are divided into sieve elements, or conducting cells, and supportive tissue. Together, xylem and phloem tissues form the vascular system of plants. Choices: - grass plants - oxygen plants - thermal plants - vascular plants A:
Ans: vascular plants

Q: What is the name of the galaxy we live in? Read this paragraph and choose the correct option from the provided answers: Like other spiral galaxies, our galaxy has a disk, a central bulge, and spiral arms. The disk is about 100,000 light-years across and 3,000 light-years thick. Most of the Galaxy's gas, dust, young stars, and open clusters are in the disk. Choices: - Centaurus A - Andromeda - Bode's Galaxy - milky way A:
(A).
milky way

Ques:Q: Thylakoid membranes contain molecules of what green pigment used in photosynthesis? Read this paragraph and choose the correct option from the provided answers: The structure of a chloroplast shows how membrane and molecular architecture helps life processes. A chloroplast consists of thylakoid membranes surrounded by stroma. The thylakoids stack on top of each other, like a stack of pancakes. The thylakoid stacks arrange chlorophyll, accessory pigment molecules, and photosynthetic proteins to capture sunlight and allow a concentration of ions within the sacs. You can see the green color of the chlorophyll. You cannot see the electron carriers, sequenced within the sac membranes, but their arrangement helps harvest small amounts of energy from excited electrons. The thylakoid membranes contain molecules of the green pigment chlorophyll. Choices: - carbonate - sodium - copper - chlorophyll A:

Ans:chlorophyll

Q: What is it called when liquid water falls from the sky? Read this paragraph and choose the correct option from the provided answers: Choices: - sedimentation - water cycling - erosion - precipitation A:
precipitation
