Question

1. organ systems work together to meet the needs of the human body. how is the skeletal system related to the nervous system? body systems

the brain and spinal cord hold the skeleton together the skeleton protects the brain and spinal cord
the brain determines how the skeleton develops the skeletal system works as a part of the nervous system.

1. which statement correctly describes the way that almost all organisms in the kingdoms plantae and animalia obtain nutrients? classification of living things

plants are autotrophs, and animals are heterotrophs. both plants and animals are autotrophs.
plants are heterotrophs, and animals are autotrophs. both plants and animals are heterotrophs.

Explanation:

Question 6

To determine the correct relationship between the skeletal and nervous systems:

• Analyze each option:
• "The brain and spinal cord hold the skeleton together" is incorrect. Muscles and connective tissues hold the skeleton together, not the nervous system organs.
• "The skeleton protects the brain and spinal cord" is correct. The skull protects the brain, and the vertebral column protects the spinal cord.
• "The brain determines how the skeleton develops" is incorrect. Skeletal development is influenced by genetics, hormones, and other factors, not directly by the brain's determination.
• "The skeletal system works as a part of the nervous system" is incorrect. The skeletal and nervous systems are distinct organ systems with different functions.

To determine the correct nutrient - obtaining method for organisms in Plantae and Animalia:

• Recall the definitions:
• Autotrophs: Organisms that can produce their own food (e.g., plants use photosynthesis).
• Heterotrophs: Organisms that obtain food by consuming other organisms (e.g., animals eat plants or other animals).
• Analyze each option:
• "Plants are autotrophs, and animals are heterotrophs" is correct. Plants make their own food (autotrophic), while animals consume food (heterotrophic).
• "Both plants and animals are autotrophs" is incorrect because animals cannot produce their own food.
• "Plants are heterotrophs, and animals are autotrophs" is incorrect. Plants are autotrophs and animals are heterotrophs.
• "Both plants and animals are heterotrophs" is incorrect as plants can produce their own food.

Answer:

The skeleton protects the brain and spinal cord
