What is one way that humans can use water resources for recreation?

People use water in many sports because when you are active, the water in your body turns into sweat to cool you down. People drink water to replenish that water used in sweat. People also use to cool down quickly by pouring a large amount on themselves. Another use of water in recreation is in swimming.


Why isn't a large piece of kelp considered a plant?

Kelp belongs to the kingdom Chromista. Plants are photosynthetic and store energy in the form of starch. Kelp are also photosynthetic, but produce sugars and not starch. Also, kelp and other chromists have "chlorophyll c" which gives it he characteristic brownish tint. This pigment and others that chromists contain are not found in any "plant."ChromistaThe kingdom Protista has been divided into Chromista and "other protists" The chromista have closer evolutionary ties to plants, animals, and fungi than they do to other protists. They are eukaryotic and autotrophic. This group includes red/brown algae (kelp) and diatoms. The multicellular organisms in Chromista are thought to have evolved their multicellularity independently from other kingdoms. Chromo means color, and although some chromists are colorless, they are characterized by a yellowish/brownish color coming from their version of chlorophyll.Anatomy of KelpThe features of kelp look like plant features. Where a plant would have roots, kelp has a "holdfast". The purpose of the holdfast is to attach the kelp to the sea floor. It does not obtain nutrients in the way that plant roots do. The "stipe" or stalk of the kelp is analogous to the stem of plants. The blades of kelp are analogous to leaves. In some kelp, at the base of the kelp blades, there are structures called gas bladders that allow the kelp to float upright.

How do humans benefit from fungi, and can you explain one way in which they contribute to our well-being?

Humans benefit from fungi in various ways, such as providing food, medicine, and environmental benefits. One way in which fungi contribute to our well-being is through the production of antibiotics. Fungi like Penicillium produce antibiotics that help fight bacterial infections and save lives.


Do ants have the ability to perceive when you kill them?

Ants do not have the ability to perceive when you kill them in the same way that humans do. They do not experience pain or have the cognitive capacity to understand death in the same way that humans do.
