Q: What is a double membrane of the nucleus that encloses the genetic material? Read this paragraph and choose the correct option from the provided answers: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two lipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Choices: - cell wall - cell membrane - nuclear wall - nuclear enevelope A:
(Answer)
nuclear enevelope

Q: Planting a row of trees around a field or erecting a fence on a sand dune helps prevent what form of erosion? Read this paragraph and choose the correct option from the provided answers: Planting rows of trees around fields is another way to reduce wind erosion. The trees slow down the wind, so it doesn't cause as much erosion. Fences like the one in Figure below serve the same purpose. The fence in the figure is preventing erosion and migration of sand dunes on a beach. Choices: - fire - water - rain - wind A:
(Answer)
wind

Q: What is a measure of the force of gravity pulling on an object of a given mass? Read this paragraph and choose the correct option from the provided answers: Newton's second law of motion explains the weight of objects. Weight is a measure of the force of gravity pulling on an object of a given mass. It's the force (F) in the acceleration equation that was introduced above:. Choices: - scale - effect - solidity - weight A:
(Answer)
weight
