Answer:
Cellulose-digesting microorganisms live in the guts of termites and ruminant mammals. the microorganisms have a home and food, and their hosts gain more nutrition from their meals. this relationship is an example of mutualism.
Explanation:
Mutualism encompasses the ecological relationships between individuals of different species, in which both gets benefits and improve their biological functions. It usually occurs between species that have different nutritional and living requirements.
An example of this is also the nitrogen fixing bacteria (Rhizobia) and the legimunous plants, and the relationship between the Acacia and the Acacia ants.
Answer: The correct option in blank is anion.
Explanation: Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.
Example: The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.
Gold, Silver, Mercury, Iron and etc.
Answer:
A group of parasites called myxozoans have traditionally been considered simple multicellular protists. However, because these organisms possess stinging cells, some scientists consider them to be animals in the phylum that is named for such cells, the <u>cnidarians</u>.
Explanation:
Cnidarians are animals with radial symmetry, that is, their bodies can be divided, by different planes, into equal parts. It includes hydras, jellyfish, anemones and marine corals. Its body is a kind of sac with an opening (the mouth) surrounded by a circle of tentacles. Some have a dominant jellyfish phase, others polyp, or both. They present defensive nematocysts with stinging action.
Underwater Ways!
The Aquarius Reef Base is an underwater habitat 5.4 meters off Key Largo in the Florida Keys National Marine Sanctuary. It is deployed on the ocean floor 62 ft below the surface and next to a deep coral reef called Conch Reef.
(That is all I can tell you.)
