Answer the following question given this paragraph: The weight of an object is the force pulling the object downward. On Earth, this would be the gravitational force of the Earth on the object. On the moon, this would be the gravitational force of the moon on the object. The gravitational force of the moon is one-sixth the magnitude of the gravitational force of the Earth; the weight of the moon rock on the moon will be one-sixth the weight of the moon rock on the Earth's surface. Weight is measured in force unitsnewtonsby a calibrated spring scale as shown here. Q: What is the force pulling an object downward called? Choices: - momentum - density - magnetism - weight A:
weight

(Answer)
microevolution
Ques: Answer the following question given this paragraph: No physical object can travel faster than the speed of light in a vacuum. (Maximum speed is finite). Q: Genetic variation helps ensure that some organisms will survive if what happens? Choices: - they get eaten - there's an earthquake - they die - their environment changes A:
Ans: their environment changes
(Q).
Answer the following question given this paragraph: An important concept in biology is that form follows function. In other words, the structure of an organism, or part of an organism, depends on its function. Apply this concept to plants, and explain why plants have different types of cells and tissues. Q: What concept can be applied to biology, because the structure of an organism, or part of an organism, depends on its function? Choices: - motion follows function - attachment follows function - form follows use - form follows function A:
(A).
form follows function
Ques:Answer the following question given this paragraph: The stems of all vascular plants get longer through primary growth. This occurs in primary meristem at the tips and nodes of the stems. Most stems also grow in thickness through secondary growth. This occurs in secondary meristem, which is located in and around the vascular tissues. Secondary growth forms secondary vascular tissues and bark. In many trees, the yearly growth of new vascular tissues results in an annual growth ring like the one in Figure below . When a tree is cut down, the rings in the trunk can be counted to estimate the tree's age. Q: The stems of all vascular plants get longer through primary growth. this occurs in primary meristem at the tips and ______ of the stems. Choices: - edges - bottoms - layers - nodes A:

Ans:nodes
Answer the following question given this paragraph: Some modern seed plants are gymnosperms that produce seeds in cones. Q: What term is used to describe modern seed plants that produce seeds in cones? Choices: - angiosperms - deciduous - perennials - gymnosperms A:
gymnosperms
