This interactive worksheet challenges students to correctly place terms like 'monosaccharide' and 'amino acids' into a biomolecules concept map to complete the biological hierarchy.

Explanation:
We need to fill in the concept map with the correct terms from the list:
Fatty acid, lean meat, lipids, monosaccharide, Proteins, nucleic acids, nucleotide, starch

Let’s break down the biomolecule categories and their parts:

1. Biomolecules are grouped into 4 main types:
- Carbohydrates
- Lipids
- Proteins
- Nucleic acids

So the top-level blank (right of “Carbohydrates” and connected by “such as”) should be Lipids, then another one for Proteins, and another for Nucleic acids.

Now let’s trace each branch:

- Carbohydrates
- Monomer = monosaccharide
- Examples: one is starch (a polysaccharide), and another common example is glucose — but from the list, only starch fits as an example. So one “for example” box under Carbohydrates = starch
- The other “for example” box? Wait — looking at the diagram: under Carbohydrates, there are two “for example” boxes. One is connected directly (likely starch), and the other may be something else — but from the given list, only starch is a carb example. Let’s hold that and check others.

- Lipids
- Monomer = fatty acid (lipids like triglycerides are made of glycerol + fatty acids; fatty acid is the key building block listed)
- Example: oil is already placed (given in diagram), so the “for example” box next to oil is probably not needed — but wait, oil is already filled in. There's also a blank box labeled “Oil” — actually, in the diagram, “Oil” is already written in a box, so we don’t fill that. Instead, the blank *above* Oil (connected by “monomer”) should be fatty acid.

- Proteins
- Monomer = amino acids (already filled in the diagram — good)
- Example: lean meat is a food source rich in protein → so “for example” under Proteins = lean meat
- Also, the category label above amino acids should be Proteins

- Nucleic acids
- Monomer = nucleotide
- Example: DNA is already filled
- Category label = nucleic acids

Now let’s map all blanks step by step using the diagram structure:

Top level (4 branches from Biomolecules):
1. Carbohydrates — already labeled
2. [Blank 1] → should be Lipids
3. [Blank 2] → should be Proteins
4. [Blank 3] → should be nucleic acids

Next, under each:

- Carbohydrates:
- monomer → monosaccharide
- for example (two boxes): one is starch, the other? From list, only starch is a carb example. But wait — the list has exactly 8 terms, and we have 8 blanks? Let’s count blanks in diagram:

Looking carefully at the diagram (mentally reconstructing):

From “Biomolecules” → 4 branches:
- Carbohydrates (labeled)
- [Box A] → lipids
- [Box B] → proteins
- [Box C] → nucleic acids

Under Carbohydrates:
- monomer → [Box D] = monosaccharide
- for example → [Box E] = starch
- another for example? Actually, there are two “for example” boxes under Carbohydrates — but only one term left? Let’s list all blanks:

Boxes to fill (dotted-line rectangles):
1. Top right branch (category) → ?
2. Middle branch (category, left of nucleic acids) → ?
3. Rightmost top category → ?
4. Under Carbs: monomer → ?
5. Under Carbs: example 1 → ?
6. Under Carbs: example 2 → ?
Wait — no, looking again: The diagram shows:

- Carbohydrates has:
- one “monomer” arrow → blank
- two “for example” arrows → two blanks

- Then there’s a middle branch (probably Lipids) with:
- category blank
- monomer blank (points to “Oil” which is given)
- one “for example” blank (but Oil is already there, so maybe that blank is the monomer?)

Actually, better approach: match each term to its role.

Given terms:
- Fatty acid → monomer of lipids
- lean meat → example of proteins
- lipids → biomolecule category
- monosacfraccharide → monomer of carbs
- Proteins → biomolecule category
- nucleic acids → biomolecule category
- nucleotide → monomer of nucleic acids
- starch → example of carbohydrate

That’s 8 terms → 8 blanks.

Now locate 8 blanks in diagram:

1. Top-right category (next to Carbohydrates) → lipids
2. Next category (middle) → Proteins
3. Far-right top category → nucleic acids
4. Under Carbohydrates: monomer → monosaccharide
5. Under Carbohydrates: one example → starch
6. Under Lipids branch: monomer → fatty acid
7. Under Proteins branch: example → lean meat
8. Under Nucleic acids branch: monomer → nucleotide

Yes — that’s 8.

Confirm connections:
- “Oil” is already placed under lipids as an example (so we don’t fill that box — it’s given). The blank *above* Oil (with “monomer” arrow pointing to Oil) is actually misread — no: the arrow says “monomer” pointing *from* a blank *to* “Oil”? No — in concept maps, “monomer” label is on the arrow *from* category to monomer. So:

Correct flow:
- Biomolecules → Carbohydrates
- Carbohydrates —(monomer)→ monosaccharide
- Carbohydrates —(for example)→ starch
- Carbohydrates —(for example)→ ???? Wait, only one carb example in list.

Hold on — re-examining: The diagram actually has only one “for example” box under Carbohydrates that is blank; the other “for example” leads to a blank box that connects also to another category? No.

Let me reconstruct based on standard worksheet layout (common LiveWorksheets biomolecule map):

Typical structure:
- Biomolecules
├─ Carbohydrates
│ ├─ monomer: ______
│ └─ examples: ______ , ______
├─ Lipids
│ ├─ monomer: ______
│ └─ examples: Oil, ______
├─ Proteins
│ ├─ monomer: amino acids (given)
│ └─ examples: ______
└─ Nucleic Acids
├─ monomer: ______
└─ examples: DNA (given)

But in our list, we have only 8 terms, and likely 8 blanks.

Given that “Oil” and “DNA” and “amino acids” are already placed in the diagram (visible in image), the blanks are the dotted boxes only.

From the user’s image description (text), the dotted boxes are:
- Top right category (blank)
- Middle category (blank)
- Right category (blank)
- Under Carbs: monomer (blank)
- Under Carbs: example (blank)
- Under middle branch: monomer (blank)
- Under middle branch: example (blank) — but Oil is already there, so maybe that example blank is something else?
Wait — the text shows:
“Oil” is in a box (not blank), and “DNA” is in a box, “amino acids” is in a box.

So blanks are:
1. Category right of Carbohydrates → lipids
2. Category below that (middle) → Proteins
3. Far right top category → nucleic acids
4. Carbs → monomer → monosaccharide
5. Carbs → example → starch
6. Lipids → monomer → fatty acid
7. Proteins → example → lean meat
8. Nucleic acids → monomer → nucleotide

Yes — all 8 terms used, no extra.

Final assignment:
- Top-level blanks (3): lipids, Proteins, nucleic acids
- Carbs branch: monomer = monosaccharide; example = starch
- Lipids branch: monomer = fatty acid
- Proteins branch: example = lean meat
- Nucleic acids branch: monomer = nucleotide

All terms placed correctly.

Final Answer:
lipids, Proteins, nucleic acids, monosaccharide, starch, fatty acid, lean meat, nucleotide
