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.
Answer:
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.
Basically an hype tonic blood has high solute potential,( low water potential) compare with the surrounding plasma and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.
Consequently,water with higher potential moves from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).
Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,

Answer:
The answer is B
Explanation:
It uses carbon, light, and water but not chemical because it doesn't produce.

subtract venus distance from earth distance to get distance between the 2
then convert au per year to km per year
then divide distance by km per year
