A Venn diagram (2 overlapping circles) illustrates the characteristics that prokaryotic cells and eukaryotic cells have in common. Both prokaryotic and eukaryotic cells have ribosomes, cell membranes, and DNA. Prokaryotic cells have circular DNA and an always present cell wall. Eukaryotic cells have a nucleus, membrane-bound organelles, and a sometimes present cell wall.

Text reads: "LabXchange came as a game changer for us because through the platform, we're now able to reach our learners virtually, and also during face-to-face classes we can use simulations, videos, and resources. We were the first cohort trained, 18 of us, around September 2023. Now there's been a ripple effect from 18 to about 2,000."

Diagram titled ‘Negative feedback loop’ showing regulation of rising body temperature. An increase in body temperature triggers vasodilation and activation of sweat glands. This leads to heat being released from the skin and the body cooling. A minus (–) symbol indicates the response inhibits the original change.
Photosynthesis takes place in chloroplasts, which have an outer membrane and an inner membrane. Stacks of thylakoids called grana form a third membrane layer.
