Cnidarians have two body forms—polyp and medusa—which often occur within the life cycle of a single cnidarian. The body of a medusa, commonly called a jellyfish, usually has the shape of a bell or an umbrella, with tentacles hanging downward at the margin.
An example of the polyp form is found in the genus Hydra, whereas the most typical form of medusa is found in the group called the “sea jellies” (jellyfish). Polyp forms are sessile as adults, with a single opening (the mouth/anus) to the digestive cavity facing up with tentacles surrounding it.

Answer:
The molar mass of the solute is 322.9 g/mol
Explanation:
Boiling point elevation to solve this:
ΔT = Kb . m
ΔT = T° boiling of solution - T°boiling of pure solvent
Kb → Ebullioscopic constant, for water is 0.512°C / m
m → molality
101.11°C - 100°C = 0.512 °C/m . m
1.11°C / 0.512 m/°C = m
2.17 = m → These are the moles of solute in 1kg of solvent
1kg = 1000 g. Let's make the rule of three to determine the moles in our solvent volume:
In 1000 g we have 2.17 moles of solute
In 100 g we may have (100 . 2.17)/1000 = 0.217 moles
The moles we obtained, are the moles for 70 g of mass.
Let's determine the molar mass: (g/mol)
70 g/ 0.217 mol = 322.9 g/mol
It’s put an heat ✦ and pressure pointing from metamorphic rocks to igneous rocks
<u>Answer:</u> The product formed in the solution is 
<u>Explanation:</u>
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
The chemical equation for the reaction of magnesium chloride and lead nitrate follows:
By Stoichiometry of the reaction:
1 mole of aqueous magnesium chloride reacts with 1 mole of aqueous lead nitrate to produce 1 mole of solid lead chloride and 1 mole of aqueous magnesium nitrate
Hence, the product formed in the solution is
