Question

1. which of the following activities occurs in both prokaryotic cells and eukaryotic cells? a. proteins are assembled on ribosomes. b. a large central vacuole stores dna and rna. c. mitochondria provide energy for cell processes. d. chloroplasts capture and transform the energy of sunlight. 8. nayla is planning an investigation on the role of osmosis in maintaining homeostasis. she plans to study red blood cells in a liquid suspension, similar to blood plasma. for nayla to observe the greatest variety of osmotic activity in the red blood cells, she should test the effect of which of these independent variables? a. temperature of the liquid suspension

Explanation:

7.

Proteins are assembled on ribosomes in both prokaryotic and eukaryotic cells. Prokaryotes lack a large central vacuole (which is common in plant - eukaryotic cells), mitochondria (prokaryotes generate energy through other means), and chloroplasts (only in photosynthetic eukaryotes like plants).

Osmosis is the movement of water across a semi - permeable membrane. The concentration of solutes in the liquid suspension affects the osmotic gradient. Temperature can also affect the kinetic energy of water molecules and thus osmosis. However, the solute concentration has a more direct impact on the osmotic activity.

Answer:

a. Proteins are assembled on ribosomes.
