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

Which statement about hf is true? it is zero for any compound in its standard state. it is positive when the bonds of the product store more energy than those of the reactants. it is negative when a compound forms from elements in their standard states. it is zero for any element that is in the liquid state.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.

Is the genie in the bottle experiment a physical or chemical change/reaction?
