The answer is; SET B

Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up  into globules so they don’t interact with water.

. If a substance changes form one phase to another, is it still the same substance?
gladu [14]

Answer:

Yes

Explanation:

A phase change does not change the chemical make-up of a substance.  Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance.  Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds.  That stays the same whether the water is solid (ice), liquid (water), or gas (steam).  The chemical structure of water does not change as it goes through the different faces.  It's still water.  What does change is the speed at which the molecules move and how far apart they are as a result.  Water vapor consists of molecules moving quickly and at random.  As temperature drops, water molecules slow down.  Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.

La Rafflesia arnoldii es una planta tropical con una enorme flor rojo-sangre, que emite calor y despide olor a carne descompuest
Bingel [31]

Answer:

Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant

Explanation:

The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.

Its possible Endothermy characteristic  is for mimicry Its releases  heat to attract  the pollinators- blowflies.The endothermic mechanism  is well pronounced during flora development: which further buttress the fact that this  is related to pollination to attract blowflies, and not to thermoregulation.
