(Please let me know if the answer is incorrect so I can edit it :) )
Answer:
Cnidaria
→ Organisms have specialized stinging cells
→ Two type of body plans exist - polyp and medusa
Porifera
→ Organisms lack symmetry
→ Adult forms are sessile
→ Organisms obtain food by filtering water
→ Phenomenon of alternation of generation is observed.
Explanation:
Cnidaria, also known as the coelenterata, is a phylum of mostly marine animals having about 9,000 living species. Some of them include the corals, hydras, jellyfish, sea anemones, sea whips, etc. They possess specialized cells known as cnidocytes ( also known as “stinging cells”). These cells can seen around the mouth and tentacles cnidarian. They immobilize their prey with toxins. These Cnidaria have two body plans and which are polyp and medusa.
The phylum Porifera are known as the pore bearers. It has about 5000 species. Their adult forms are sessile. They live permanently attached to rocks. They can under alternation of generation. They possess no organs in their bodies. Also, they lack symmetry. They can be referred t as filter feeders because they obtain food by filtering water.
Parasitic infections are a primary cause of iron-deficiency anemia in many regions of the globe.
As the name itself says, iron-deficiency anemia is caused by a lack of iron in a person's blood, meaning that there are not enough red blood cells, leading to tiredness, weakness, shortness of breath, paleness, etc. Parasites increase the risk of anemia.
Answer:
3) non-explosive
Explanation:
Mt. Kea and Mt. Loa in Hawaii are two of the tallest volcanic mountains in the world.
Mauna Kea is a dormant volcano that is present in Hawaii Island. It is 4,207 m (13,802 ft) high. Although most of its part is under water but still when mesured from base it is the world's tallest mountain.
Mauna Loa is also among five volcanic mountain present in Hawaii Island.Heavy in both volume and mass, Mauna Loa is thought to be as biggest volcanic mountain on earth,
Interestingly, Mauna Loa and Mauna Kea both are active shield volcanoes. Lava eruptions from Mauna Loa and Mauna Kea are very fluid and silica-poor which makes them non-explosive.
Shield Volcano usually are Built of layers of lava through repeated non- explosive eruptions. Their Lava is runny (low viscosity) and the sides are gently sloping making them non-explosive.
Hope it help!
