ribosomes
Answer the following question given this paragraph: White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tractsthe latter carrying motor commands down from the brain to the spinal cord to control output to the periphery. Q: The brain is said to contain gray matter, while what related structure contains white matter separated into columns? Choices: - brain stem - amygdala - orbital lobe - spinal cord A:
spinal cord
Q: Answer the following question given this paragraph: 26.3 Angiosperms Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crops and ornamental plants are angiosperms. Their success comes from two innovative structures that protect reproduction from variability in the environment: the flower and the fruit. Flowers were derived from modified leaves. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes in pollen grains. The carpels contain the female gametes (the eggs inside. Q: What is the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species? Choices: - pteridophytes - gymnosperms - bryophytes - angiosperms A:
A: angiosperms
Question: Answer the following question given this paragraph: A: The paper is being cut into smaller pieces, which is changing its size and shape. The ice cubes are turning into a puddle of liquid water because they are melting. This is a change of state. The tablet is disappearing in the glass of water because it is dissolving into particles that are too small to see. The lighthouse is becoming coated with ice as ocean spray freezes on its surface. This is another change of state. Q: Melting ice cubes and freezing water are examples of change of what? Choices: - volume - role - role - state A:
Answer: state

Answer the following question given this paragraph: Nuclear energy is produced by splitting the nuclei of radioactive uranium. This doesn't release air pollution or carbon dioxide, but it does produce dangerous radioactive wastes. Q: What type of energy occurs by splitting the nuclei of radioactive uranium? Choices: - microwave - atomic - kinetic - nuclear A:
**Answer**
nuclear
(Q).
Answer the following question given this paragraph: Physics also tells us that, although energy can be captured or transformed, it inevitably degrades, becoming heat, a less useful form of energy. This is why organisms require a constant input of energy; the work they must do uses up the energy they take in. Energy, unlike materials, cannot be recycled. The story of life is a story of energy flow its capture, transformation, use for work, and loss as heat. Q: When energy is captured or transformed, it inevitably degrades and becomes what less useful form of energy? Choices: - chemical - temperature - motion - heat A:
(A).
heat
