Question

1. ______ isomers
2. ______ cohesion
3. ______ savannah
4. ______ saturated fat

g. a type of grassland biome that experiences, rainy seasons, and long periods of drought
h. and lipid made from fatty acids that have no double bonds between carbon atoms
i. this area has permanently frozen soil that does not allow for the growth of large plants
j. two different molecules that have the same chemical formula

Explanation:

For 41: Isomers are defined as two different molecules with the same chemical formula, matching option J.
For 42: Cohesion is a property of water (or other substances) where molecules stick together, but since the options here, we might have missed some, but based on given, maybe a typo, but assuming the context, but the given options: Wait, maybe the original question has more options, but with given, let's proceed. Wait, the user's question is about matching, so:

1. isomers: J (two different molecules with same chemical formula)
2. cohesion: (maybe a missing option, but with given, perhaps error, but assuming the options provided, maybe the user missed some, but with given, let's do as per available. Wait, the options given: G (savannah), H (saturated fat), I (tundra), J (isomers). So:

1. isomers → J
2. cohesion: (maybe a different set, but with given, perhaps the user's question has some missing, but based on the provided options, let's match:

1. savannah → G (grassland with rainy and drought)
2. saturated fat → H (lipid from fatty acids with no double bonds)

So:

1. J. two different molecules that have the same chemical formula
2. (assuming a missing option, but if we have to use given, maybe a mistake, but perhaps the user intended, but let's proceed with the given options for the ones we can:

1. isomers: J
2. savannah: G
3. saturated fat: H

For 42, cohesion: maybe a different option not provided, but with given, we can't match, but perhaps the user's question has a typo. But based on the given, let's answer the ones we can.

Answer:

1. J. two different molecules that have the same chemical formula
2. (No matching option in given, but if forced with given, maybe error)
3. G. a type of grassland biome that experiences, rainy seasons, and long periods of drought
4. H. and lipid made from fatty acids that have no double bonds between carbon atoms

(Note: For 42, cohesion is typically the attraction between molecules of the same substance, but no matching option in the provided J, G, H, I. So there might be a missing option in the original question.)
