Explanation:

Serve as a food source for other organisms: The cyanobacteria serves as a food for marine organisms like zooplanktons and fishes.

Are used for medicinal purposes: The cyanobacteria are used for the purpose of medicine these produced biologically active materials such as antiviral, antifungal, antibacterial and anticancer activities.

Produce oxygen: The cyanobacteria produces oxygen by the process of photosynthesis.

Perform nitrogen fixation: The Cyanobacteria produces nitrogen form that is absorbed by the plants. It converts the atmospheric nitrogen into the ammonia absorbed by the plants.

Cause disease: The cyanobacteria produces cytotoxin which is responsible for neurodegenerative diseases like Parkinson's disease, and  Alzheimer's disease.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
