a model of a crucial human body system. In 1 sentences, identify the body system, and explain how it interacts with the body system that is responsible for gas exchange with the external environment.

Answer 1

The circulatory system is crucial for transporting oxygen-rich blood throughout the body, working closely with the respiratory system, which facilitates gas exchange by bringing oxygen into the lungs and removing carbon dioxide from the bloodstream.

Answer 2

Organism A and Organism B, pictured below, have different organelles inside their cells. Imagine what would happen if Organism A could have some of the unique organelles of Organism B! In 1 sentences, describe which organelles Organism B has that Organism A does not, AND what functions Organism A could perform if it were possible to have Organism B's organelles!

organism A is a dog and organisim B is a flower plant

Answer 3

Organism B (the flower plant) has chloroplasts, which are absent in Organism A (the dog), and if Organism A could acquire these organelles, it could perform photosynthesis to convert sunlight into energy, potentially supplementing its energy needs.

Answer 4

Select whether the structure/description applies to prokaryotic cells only, eukaryotic cells only, or both types of cells.(
Prokaryotic Cells only Both Types of Cells Eukaryotic Cells only
Genetic material

Nucleus

No Nucleus

NO membrane bound organelles (like mitochondria)

Membrane bound organelles (like mitochondria)

Ribosomes

Answer 5

Here's how each structure/description applies:

• Genetic material: Both Types of Cells
• Nucleus: Eukaryotic Cells only
• No Nucleus: Prokaryotic Cells only
• NO membrane bound organelles (like mitochondria): Prokaryotic Cells only
• Membrane bound organelles (like mitochondria): Eukaryotic Cells only
• Ribosomes: Both Types of Cells
