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:
nodes
Answer the following question given this paragraph: 16.5 | The Coordination and Gait Exams By the end of this section, you will be able to: Explain the relationship between the location of the cerebellum and its function in movement Chart the major divisions of the cerebellum List the major connections of the cerebellum Describe the relationship of the cerebellum to axial and appendicular musculature Explain the prevalent causes of cerebellar ataxia The role of the cerebellum is a subject of debate. There is an obvious connection to motor function based on the clinical implications of cerebellar damage. There is also strong evidence of the cerebellar role in procedural memory. The two are not incompatible; in fact, procedural memory is motor memory, such as learning to ride a bicycle. Significant work has been performed to describe the connections within the cerebellum that result in learning. A model for this learning is classical conditioning, as shown by the famous dogs from the physiologist Ivan Pavlov's work. This classical conditioning, which can be related to motor learning, fits with the neural connections of the cerebellum. The cerebellum is 10 percent of the mass of the brain and has varied functions that all point to a role in the motor system. Q: Comprising 10 percent of the mass of the brain, what structure has varied functions that all point to a role in the motor system? Choices: - medulla oblongata - cerebrum - superior peduncle - cerebellum A:
cerebellum
Q: Answer the following question given this paragraph: During the systolic phase of the cardiac cycle, the heart is ________. contracting b. relaxing c. contracting and relaxing d. filling with blood 16. How do arteries differ from veins? a. Arteries have thicker wall layers to accommodate the changes in pressure from the heart. Arteries carry blood. Arteries have thinner wall layers and valves and move blood by the action of skeletal muscle. Arteries are thin walled and are used for gas exchange. Most of the hormones produced by the anterior pituitary perform what function? a. regulate growth b. regulate the sleep cycle c. regulate production of other hormones d. regulate blood volume and blood pressure 18. What is the function of the hormone erythropoietin? a. Q: Arteries have thinner wall layers and valves and move blood by the action of skeletal what? Choices: - marrow - collagen bands - hormones - muscle A:
A: muscle
Question: Answer the following question given this paragraph: In the single fixed pulley, only one rope segment pulls up on the load, so the ideal mechanical advantage is 1. In other words, this type of pulley doesn't increase the force that is applied to it. However, it does change the direction of the force. This allows you to use your weight to pull on one end of the rope and more easily raise the load attached to the other end. Q: What is the ideal mechanical advantage in the single fixed pulley? Choices: - zero - 2 - 4 - 1 A:
Answer: 1

Answer the following question given this paragraph: Some single-celled organisms, such as algae, live in colonies. A colony is an organized structure composed of many cells, like the Volvox sphere in Figure below . Volvox are algae that live in colonies of hundreds of cells. All of the cells in the colony live and work cooperatively. For example, they can coordinate the movement of their flagella, allowing them to swim together through the water as though they were part of a single organism. Q: What are algae that live in colonies of hundreds of cells called? Choices: - chlorophyta - euglenids - rhodophyta - volvox A:
**Answer**
volvox

Answer the following question given this paragraph: Figure 36.14 In the human ear, sound waves cause the stapes to press against the oval window. Vibrations travel up the fluid-filled interior of the cochlea. The basilar membrane that lines the cochlea gets continuously thinner toward the apex of the cochlea. Different thicknesses of membrane vibrate in response to different frequencies of sound. Sound waves then exit through the round window. In the cross section of the cochlea (top right figure), note that in addition to the upper canal and lower canal, the cochlea also has a middle canal. The organ of Corti (bottom image) is the site of sound transduction. Movement of stereocilia on hair cells results in an action potential that travels along the auditory nerve. Q: In the human ear, sound waves cause the stapes to press against what? Choices: - yellow window - shaped window - Idea Window - oval window A:
**Answer**
oval window
