Answer the following question given this paragraph: Descending fibers from the cerebrum have branches that connect to neurons in the pons. Those neurons project into the cerebellum, providing a copy of motor commands sent to the spinal cord. Sensory information from the periphery, which enters through spinal or cranial nerves, is copied to a nucleus in the medulla known as the inferior olive. Fibers from this nucleus enter the cerebellum and are compared with the descending commands from the cerebrum. If the primary motor cortex of the frontal lobe sends a command down to the spinal cord to initiate walking, a copy of that instruction is sent to the cerebellum. Sensory feedback from the muscles and joints, proprioceptive information about the movements of walking, and sensations of balance are sent to the cerebellum through the inferior olive and the cerebellum compares them. If walking is not coordinated, perhaps because the ground is uneven or a strong wind is blowing, then the cerebellum sends out a. Q: Descending fibers from the cerebrum have branches that connect to neurons in the pons. those neurons project into the cerebellum, providing a copy of motor commands sent to this? Choices: - neurotransmitters - umbilical cord - cerebral cortex - spinal cord A:
spinal cord

Answer the following question given this paragraph: Protection. The skeleton supports and protects the soft organs of the body. For example, the skull surrounds the brain to protect it from injury. The bones of the rib cage help protect the heart and lungs. Q: What supports and protects the soft organs of the body? Choices: - Skin - skull - Muscle - skeleton A:
(Answer)
skeleton
Ques: Answer the following question given this paragraph: Hormones control many cell activities, so they are very important for homeostasis. But what controls the hormones themselves? Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range. Q: What is the term for a loop in which a product feeds back to control its own production? Choices: - Recondition Mechanism - load mechanism - Adaptive Mechanism - feedback mechanism A:
Ans: feedback mechanism

Answer the following question given this paragraph: Physical chemistry is the study of macroscopic properties, atomic properties, and phenomena in chemical systems. A physical chemist may study such things as the rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level. Q: What is the study of macroscopic properties, atomic properties, and phenomena in chemical systems? Choices: - differential chemistry - thermal chemistry - molecular chemistry - physical chemistry A:
(A).
physical chemistry
Ques:Answer the following question given this paragraph: Q: What do we call the scientific study of heredity and hereditary variation? Choices: - geneology - biology - chemistry - genetics A:

Ans:genetics
Ques:Answer the following question given this paragraph: When two or more waves meet, they interact with each other. The interaction of waves with other waves is called wave interference . Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. Amplitude is the maximum distance the particles of the medium move from their resting positions when a wave passes through. How amplitude is affected by wave interference depends on the type of interference. Interference can be constructive or destructive. Q: What is the interaction of waves with other waves called? Choices: - wave mixing - wave induction - wave dancing - wave interference A:

Ans:
wave interference
