Answer the following question given this paragraph: The warm air at the cold front rises and creates a low pressure cell. Winds rush into the low pressure. This creates a rising column of air. The air twists, rotating counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Since the rising air is moist, rain or snow falls. Q: What is created when the warm air at the cold front rises and creates a low pressure cell, causing winds to rush into the low pressure? Choices: - Tornado - Hurricane - Wind pressure - rising air column A:
rising air column

stimuli
Ques: Answer the following question given this paragraph: Leaves may vary in size, shape, and their arrangement on stems. Nonflowering vascular plants have three basic types of leaves: microphylls ("tiny leaves"), fronds, and needles. Figure below describes each type. Q: Nonflowering vascular plants have three basic types of leaves: microphylls, fronds, and what other type? Choices: - molds - tubes - stems - needles A:
Ans: needles
(Q).
Answer the following question given this paragraph: Looking at the magnetism of the seafloor, scientists discovered something astonishing. Many times in Earth's history, the magnetic poles have switched positions. North becomes south, and south becomes north! When the north and south poles are aligned as they are now, geologists say it is normal polarity . When they are in the opposite position, they say that it is reversed polarity . Q: What is it called when poles are in opposite positions? Choices: - reversed bonding - polar effect - demagnetization - reversed polarity A:
(A).
reversed polarity
Ques:Answer the following question given this paragraph: Sometimes two air masses stop moving when they meet. These stalled air masses create a stationary front . Such a front may bring clouds and precipitation to the same area for many days. Q: What weather phenomenon, which may bring clouds and precipitation, is created by stalled air masses? Choices: - susceptible front - cool front - Horizontal Front - stationary front A:

Ans:stationary front
Question: Answer the following question given this paragraph: The main distinguishing feature of vertebrates is their vertebral column, or backbone (see Figure below ). The backbone runs from the head to the tail along the dorsal (top) side of the body. The vertebral column is the core of the endoskeleton. It allows a vertebrate to hold its shape. It also houses and protects the spinal (nerve) cord that passes through it. The vertebral column is made up of repeating units called vertebrae (singular, vertebra). In many species, there are shock-absorbing discs between the vertebrae to cushion them during movement. Q: What makes up the core of the endoskeleton? Choices: - dermis - notochord - thorax - vertebral column A:
Answer:
vertebral column
