Question

Accepted Answer

### Question 7 (Water Properties)
#### (a)
# Explanation:
## Step1: Recall water's polarity and bonding.
Water molecules form hydrogen bonds due to polarity.
## Step2: Identify the bond type.
Water sticks due to hydrogen bonds.
# Answer: hydrogen

#### (b)
# Explanation:
## Step1: Analyze the explanation.
Water sticks to itself (forms drops) → this is cohesion.
## Step2: Name the property.
The property is Cohesion.
# Answer: Cohesion

#### (c)
# Explanation:
## Step1: Analyze the explanation.
Water adheres to other surfaces (e.g., glass) → this is adhesion.
## Step2: Name the property.
The property is Adhesion.
# Answer: Adhesion

#### (d)
# Explanation:
## Step1: Analyze the explanation.
Water travels up tubes (adhesion + cohesion) → this is capillary action. Example: water moving up plant stems (xylem).
## Step2: Name the property and example.
Property: Capillary Action; Example: water moving up a plant stem (xylem).
# Answer: Capillary Action (example: water moving up a plant stem)

#### (e)
# Explanation:
## Step1: Recall water's density when frozen.
Water expands (becomes less dense) when frozen.
## Step2: State the change.
Water expands when frozen.
# Answer: expands

### Question 8 (pH Scale)
#### First blank (0 - 6.9)
# Explanation:
## Step1: Recall pH definitions.
pH 0 - 6.9 → acidic.
## Step2: Fill the blank.
Substances with pH 0 - 6.9 are acidic.
# Answer: acidic

#### Second blank (7.1 - 14)
# Explanation:
## Step1: Recall pH definitions.
pH 7.1 - 14 → basic (alkaline).
## Step2: Fill the blank.
Substances with pH 7.1 - 14 are basic.
# Answer: basic

### Question 9 (Carbon Covalent Bonds)
# Explanation:
## Step1: Recall carbon's valence electrons.
Carbon has 4 valence electrons, so it forms 4 covalent bonds.
## Step2: State the number.
A carbon atom can form 4 covalent bonds.
# Answer: 4

### Question 10 (Organic Substances)
#### A)
# Explanation:
## Step1: Recall organic chemistry definition.
All organic substances contain carbon (C).
## Step2: State the element.
All organic substances contain the element carbon.
# Answer: carbon

#### B)
# Explanation:
## Step1: Recall 4 main organic molecules.
The four are carbohydrates, lipids, proteins, nucleic acids.
## Step2: List them.
Four organic molecules: Carbohydrates, Lipids, Proteins, Nucleic Acids.
# Answer: Carbohydrates, Lipids, Proteins, Nucleic Acids

### Question 11 (Monomers and Polymers)
# Explanation:
## Step1: Recall the relationship.
Monomers (small units) join to form polymers (large chains).
## Step2: Fill the blanks.
Monomers join together to build polymers.
# Answer: Monomers; polymers

### Question 12 (Macromolecules Table)
#### Lipids (a, b)
# Explanation:
## Step1: Recall lipid functions.
Lipids: a) Store energy; b) Form cell membranes (phospholipids), insulation, etc.
## Step2: Fill the blanks.
a) Store energy; b) Form cell membranes (or insulation, etc.).
# Answer: a) Store energy; b) Form cell membranes (example - phospholipid)

#### Proteins (c, d, e)
# Explanation:
## Step1: Recall protein monomers and functions.
c) Monomer: Amino Acids; d) Function: Catalyze (enzymes) reactions, growth/repair, etc.; e) Example: Enzyme (e.g., amylase), or hemoglobin, insulin.
## Step2: Fill the blanks.
c) Amino Acids; d) Catalyze; e) Amylase (or hemoglobin, etc.).
# Answer: c) Amino Acids; d) Catalyze; e) Amylase (example)

#### Carbohydrates (f, g)
