Answer:
Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons. A proton carries one unit of positive† charge (Dufay's vitreous electricity) and an electron carries one unit of negative charge (Dufay's resinous electricity). A neutron carries no charge; it is neutral.

Describe what will happen when a red blood cell is placed in:
- hypotonic solution
- hypertonic solution
- isotonic solution
In your description you must write about:
- water movement
- what will happen to the cell.
Answer:
Describe what will happen when a red blood cell is placed in:
Hypotonic Solution ⇒ The red cell would burst due to the influx of water. The water would have moved out of the cell which cause it to shrink. Red blood cells don't have the cell wall and contractile vacuoles and as well as it would not be able to maintain their shape leading to their rupture.
Hypertonic solution ⇒ A cell loses its H2O molecules when it is placed in hypertonic solution. Hypertonic solution is the one which contain more concentration of solutes as compared to the concentration of solutes in cytoplasm of cell. Which means that a solution contains less water as compared to the water within the cell.
Isotonic solution ⇒ When a red blood cell is placed in an isotonic solution, there will be no movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly

Which are characteristics of bryophytes? (Select all that apply.)
Most of them need water to help reproduce.
Most of them grow tall.
Most of them live in shady, moist, or humid areas.
Most of them are vascular plants.
Answer:
most of them are vascular plants
most of them grow tall
Explanation:
The characteristics of bryophytes are:
Most of them need water to help reproduce.
Most of them live in shady, moist, or humid areas.
What are bryophytes ?Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. They are small, simple plants that lack true roots, stems, and leaves. As non-vascular plants, they do not have a system of tubes or vessels for transporting water and nutrients, and thus they rely on diffusion and osmosis for these functions.
Due to their lack of vascular tissue, bryophytes cannot grow tall like vascular plants. Instead, they tend to form low, carpet-like mats on the ground or on other surfaces.
Because they require water for reproduction, they are commonly found in moist, shady areas where they can absorb water directly from the environment.
Bryophytes play an important ecological role in their environments, serving as habitat for a variety of small organisms, contributing to nutrient cycling, and helping to prevent soil erosion. Despite their small size and lack of vascular tissue, they are a diverse and widespread group of plants that have adapted to a variety of different habitats around the world.
Another adaptation of bryophytes is their ability to store water in specialized cells called hydroids, which can help to prevent dehydration in dry conditions. Some species of bryophytes also have structures called gemmae, which are small, multicellular reproductive structures that can detach from the parent plant and grow into new individuals under favorable conditions.

Describe how the total energy in the ecosystem is conserved within the ecosystem in a bottle.
Answer:
The warmth from the sunlight causes the excess water in the terrarium to evaporate and rise to the top of the bottle. Once the water vapor reaches the top of the glass, it cools and condenses back into liquid droplets. These droplets drip back down onto the moss, creating 'rain' to keep the ecosystem moist.
