The limitation of using a 2D computer-generated image of the digestive system instead of the actual thing is that the 2D image is less accurate in showing how the organs look, such as their texture.
What is one limitation of a using a 2D computer generated image of the digestive system instead of using the actual thing? (1 point)
Responses
The 2D image is messy and does not show how the organs are connected to each other.

The 2D image is too small and the organs are, therefore, difficult to see.

The organelle where amino acids are synthesized into proteins is the ribosome. However, without specific labeling or context for "1," "2," "3," or "4," I cannot directly correlate to a specific number in your responses. Generally, ribosomes can either be found floating freely in the cytoplasm or attached to the endoplasmic reticulum (forming rough ER).

If the chloroplasts in a plant's cells became damaged, the plant would not make glucose and oxygen. Chloroplasts are essential for photosynthesis, the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen.
A student wanted to understand how organisms reacted to the high atmospheric temperatures of early Earth. The student designed an experiment to determine how temperature affects the carbon dioxide permeability of a cell membrane.
Which statement best summarizes the resulting data?
(1 point)
Responses
As temperature increased, the movement of carbon dioxide across the membrane increased slightly until it reached a maximum.
As temperature increased, the movement of carbon dioxide across the membrane increased slightly until it reached a maximum.
Carbon dioxide movement across the membrane decreased as the permeability of the membrane increased.
Carbon dioxide movement across the membrane decreased as the permeability of the membrane increased.
The rate of photosynthesis increased because more carbon dioxide passed through the membrane at higher temperatures.
The rate of photosynthesis increased because more carbon dioxide passed through the membrane at higher temperatures.
The permeability of the membrane decreased when heated, allowing more carbon dioxide to pass through the membrane.

The statement that best summarizes the resulting data is: As temperature increased, the movement of carbon dioxide across the membrane increased slightly until it reached a maximum. This suggests that there is a relationship between temperature and the permeability of the membrane for carbon dioxide, with an eventual peak where the movement stabilizes.
