Recall what you know about hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?(1 point)

Responses

The environment has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.

When an environment is hypotonic, it has a lower concentration of solutes compared to the inside of the cell. This means that the outside environment has more solvent (usually water) relative to the solute concentration. As a result, water moves into the cell to equalize the solute concentrations.

The correct response is:

The cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.

This process can lead to the cell swelling and potentially bursting if the influx of water is significant enough.

If eukaryotes all came about due to endosymbiosis, what would result from that?(1 point)
Responses

ancient prokaryotes living inside of modern eukaryotes

similar structures in eukaryotes with slight variations depending on their use
similar structures in eukaryotes with slight variations depending on their use

If eukaryotes all came about due to endosymbiosis, the most accurate result from that would be:

ancient prokaryotes living inside of modern eukaryotes.

This concept suggests that certain organelles within eukaryotic cells, such as mitochondria and chloroplasts, originated from free-living prokaryotic organisms that entered into a symbiotic relationship with ancestral eukaryotic cells.

Which type of microscopes was developed most recently?(1 point)
Responses

light-based microscope
light-based microscope

scanning tunneling microscope
scanning tunneling microscope

electron microscope
electron microscope

fluorescence microscope

The type of microscope that was developed most recently is the scanning tunneling microscope. This microscope, which allows for imaging surfaces at the atomic level, was invented in the 1980s. In comparison, light-based microscopes and electron microscopes were developed earlier in the 19th and 20th centuries, respectively, while fluorescence microscopy also has a longer history.

What is the unique function of central vacuoles in a plant cell?(1 point)
Responses

they store water
they store water

they store enzymes
they store enzymes

they store pigments
they store pigments

they store ribosomes

The unique function of central vacuoles in a plant cell is:

they store water.

Central vacuoles play a crucial role in maintaining turgor pressure, which helps keep the plant cell rigid and supports the overall structure of the plant. They can also store other substances such as ions, waste products, and pigments, but their primary and most notable function is water storage.

Neurotransmitter release is an example of ________.(1 point)
Responses

autocrine signaling
autocrine signaling

paracrine signaling
paracrine signaling

cellular miscommunication
cellular miscommunication

cyclical behavior

Neurotransmitter release is an example of paracrine signaling.

In paracrine signaling, signals (such as neurotransmitters) are released from one cell and act on nearby target cells. This is different from autocrine signaling, where a cell signals to itself, or other options that aren't specific to how neurotransmitters function.
