Ques: Q: Some gametophytes develop underground and form mycorrhizal associations with what? Read this paragraph and choose the correct option from the provided answers: Lycophytes follow the pattern of alternation of generations seen in the bryophytes, except that the sporophyte is the major stage of the lifecycle. The gametophytes do not depend on the sporophyte for nutrients. Some gametophytes develop underground and form mycorrhizal associations with fungi. In club mosses, the sporophyte gives rise to sporophylls arranged in strobili, cone-like structures that give the class its name. Lycophytes can be homosporous or heterosporous. Choices: - protists - plants - animals - fungi A:
Ans: fungi

Q: What are the blood vessels that carry blood toward the heart and tend to have thinner walls? Read this paragraph and choose the correct option from the provided answers: Veins are blood vessels that carry blood toward the heart. This blood is no longer under pressure, so veins have thinner walls. To keep the blood moving, many veins have valves that prevent the backflow of blood. Veins generally carry oxygen-poor blood. The smallest veins are called venules. They merge to form larger and larger veins. The largest vein is the inferior vena cava, which carries blood from the lower body directly to the heart. Choices: - capillaries - glands - clots - veins A:
(A).
veins

Ques:Q: Bacteria reproduce through what process, where the chromosome copies itself, forming two genetically identical copies? Read this paragraph and choose the correct option from the provided answers: Bacteria reproduce through a process called binary fission . During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell. Binary fission can happen very rapidly. Some species of bacteria can double their population in less than ten minutes!. Choices: - multiple fission - residual fission - nuclear fission - binary fission A:

Ans:binary fission

Q: Solution nodes and antinodes are both areas of wave interference, but they differ in the presence of what condition? Read this paragraph and choose the correct option from the provided answers: Check Your Understanding Define nodes and antinodes. Solution Nodes are areas of wave interference where there is no motion. Antinodes are areas of wave interference where the motion is at its maximum point. Choices: - radiation - gravity - speed - motion A:
motion
