Answer: B) Cerebellum Explanation: The cerebellum is a small part of the brain positioned at the back of the head, where it meets the spine, which acts as the body's movement and balance control centre.     It's a lot smaller than the cerebrum at only 1/8 of its size. But it's a very important part of the brain.

Answer: A) quality, quantity and duration of light Explanation: Plants and animals are separated by about 1.5 billion years of evolutionary history. They have evolved their multicellular organization independently but using the same initial toolkit — the set of genes inherited from their common unicellular eucaryotic ancestor. Two basic peculiarities of plants are: First, they get their energy from sunlight, not by ingesting other organisms. This dictates a body plan different from that of animals. Second, their cells are encased in semirigid cell walls and cemented together, preventing them from moving as animal cells do. This dictates a different set of mechanisms for shaping the body and different developmental processes to cope with a changeable environment. Because they cannot match themselves to their environment by moving from place to place, plants adapt instead by altering the course of their development. Their strategy is opportunistic. A given type of organ—a leaf, a flower, or a root, say—can be produced from the fertilized egg by many different paths according to environmental cues.   Hence, Plant development is influenced by quality, quantity and duration of light.
