Many sponges can reproduce asexually. ladybugs, on the other hand, reproduce sexually.
when small bits of a sponge are broken off-often by currents or by predators--they can float to new
regions and regenerate as new sponges. a ladybug must find a mate before it can reproduce.
one disadvantage of the sponge's method of reproduction is that

It can die

Explanation:

b) it's offspring have little genetic diversity.

Explanation:

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
