The push factors for early human migration include environmental changes, scarcity of resources, and conflicts within groups, while the pull factors consist of the search for new opportunities, better living conditions, and the discovery of new territories.

You're welcome! If you have any more questions, feel free to ask.
1. The role of the nervous system in digestion is D. to provide electrical signals to initiate peristalsis. Peristalsis is the process by which food is pushed through the digestive tract.
2. Most of the absorption of nutrients occurs in the D. small intestine. The small intestine has specialized structures called villi that increase its surface area, allowing for efficient absorption of nutrients.
3. The pizza that you ate for lunch is being digested in your stomach by being B. churned, mixing it with digestive enzymes and gastric acid. The stomach uses muscular contractions to mix the food with digestive enzymes and gastric acid, breaking it down into smaller particles.
4. The nervous system influences the respiratory system by A. controlling muscle contraction. The muscles involved in breathing, such as the diaphragm and intercostal muscles, are controlled by the nervous system.
5. The system comprising skin, hair, and other parts of the outermost layer of the body is the C. integumentary system. This system plays a role in protection, temperature regulation, and sensory perception.
1. The correct answer is D. The role of the nervous system in digestion is to provide electrical signals to initiate peristalsis. To get the answer, you can understand the functions of the nervous system and the process of digestion. The nervous system controls and coordinates the activities of the body, including the digestive system. Peristalsis is a rhythmic contraction and relaxation of the muscles in the digestive tract that propels food along the digestive system.
2. The correct answer is D. Most of the absorption of nutrients occurs in the small intestine. To get the answer, you can study the anatomy and function of the digestive system. The small intestine is where most of the digestion and absorption of nutrients takes place. It has a large surface area for absorption due to its numerous folds and projections called villi.
3. The correct answer is B. In the stomach, the pizza is churned, mixing it with digestive enzymes and gastric acid. To get the answer, you can understand the process of digestion in the stomach. The stomach is a muscular organ that mechanically breaks down food through churning motions and mixes it with digestive enzymes and gastric acid to begin the process of digestion.
4. The correct answer is A. The nervous system influences the respiratory system by controlling muscle contraction. To get the answer, you can study the functions of the nervous system and the respiratory system. The nervous system controls the contraction of muscles involved in breathing, such as the diaphragm and intercostal muscles.
5. The correct answer is C. The integumentary system comprises of skin, hair, and other parts of the outermost layer of the body. To get the answer, you can study the different systems of the body and their components. The integumentary system is responsible for protecting the body and regulating temperature, and it includes the skin, hair, nails, sweat glands, and oil glands.
