Homework Answers
189) Answer : b) They all have foliated texture
Explanation :Slate, gneiss and schist are three common foliated metamorphic rocks.
Slate is a hard, fine-grained rock with a well-developed rock cleavage or slaty cleavage caused by the incipient growth of platy minerals, due to metamorphism of fine-grained clastic sediments such as shale and siltstone and also volcanic tuffs.
Schist is a still higher degree of metamorphism, characterized by coarse grained foliation and/or lineation, with mica crystals large enough to be easily identified with the unaided eye.
Gneiss is a medium to coarse-grained, irregularly banded rock with only poorly developed cleavage.
190) Answer : b)Precambrian shield
Explanation : This shield is also called the Laurentian Plateau, is a large area of exposed Precambrian igneous and high-grade metamorphic rocks that forms the ancient geological core of the North American continent.

Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...
