Answer the following question given this paragraph: Fixed joints do not allow any bone movement. Many of the joints in your skull are fixed ( Figure below ). There are eight bones that fuse together to form the cranium. The joints between these bones do not allow movement, which helps protect the brain. Q: How many bones fuse together to form the cranium? Choices: - 6 - 3 - 8 - 8 A:
8
Answer the following question given this paragraph: Electromagnetism is associated with charge and is a fundamental force of nature, like gravity. If charges are static, the only manifestation of electromagnetism is the Coulomb electric force. In the same way that gravitational force depends on mass, the Coulomb electric force depends on the property known as electric charge. Like gravity, the Coulomb electric Force decreases with the square of the distance. The Coulomb electric force is responsible for many of the forces we discussed previously: the normal force, contact forces such as friction, and so on - all of these forces arise in the mutual attraction and repulsion of charged particles. Q: What property does coulomb electric force depend upon? Choices: - electric case - electric neutral - electric half - electric charge A:
electric charge
Q: Answer the following question given this paragraph: Q: What step, involving placement of a substance on the stigma, precedes fertilization? Choices: - mitosis - spawning - hibernation - pollination A:
A: pollination
Question: Answer the following question given this paragraph: The deadly nerve gas Sarin irreversibly inhibits acetycholinesterase. What effect would Sarin have on muscle contraction? After depolarization, the membrane returns to its resting state. This is called repolarization, during which voltagegated sodium channels close. Potassium channels continue at 90% conductance. Because the plasma membrane sodiumpotassium ATPase always transports ions, the resting state (negatively charged inside relative to the outside) is restored. The period immediately following the transmission of an impulse in a nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse, is called the refractory period. During the refractory period, the membrane cannot generate another action potential. The refractory period allows the voltage-sensitive ion channels to return to their resting configurations. The sodium potassium ATPase continually moves Na+ back out of the cell and K+ back into the cell, and the K+ leaks out leaving negative charge behind. Very quickly, the membrane repolarizes, so that it can again be depolarized. Q: The period immediately following the transmission of an impulse in a nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse, is called the ______ period. Choices: - activation - extraction - interstitial - refractory A:
Answer: refractory

Answer the following question given this paragraph: Gymnosperms are vascular plants that produce seeds in cones. Examples include conifers such as pine and spruce trees. The gymnosperm life cycle has a very dominant sporophyte generation. Both gametophytes and the next generation's new sporophytes develop on the sporophyte parent plant. Figure below is a diagram of a gymnosperm life cycle. Q: What are vascular plants that produce seeds in cones called? Choices: - evergreen - deciduous - angiosperms - gymnosperms A:
(Answer)
gymnosperms
