Step-by-step solution for: Amoeba sisters punnett practice worksheet
Let's go through the worksheet and complete the missing components of the table, based on the context provided in the image. The goal is to explain how each illustration relates to water, complete the comic section (which seems partially filled), and provide examples of importance for living organisms.

| Explain how illustration can relate to water? | Comic | Example of importance for living organisms? |
|--------------------------------------------------|-----------|-----------------------------------------------|
| Answer: The illustration shows that it takes a lot of heat energy to raise the temperature of water. This is because water has a high specific heat capacity — meaning it can absorb a lot of heat without a large increase in temperature. The thermometer shows a small change in temperature even after adding heat. | *Illustration: A drop of water with a thermometer showing low temp → heated by flame → same drop, slightly warmer temp.* | Answer: It helps regulate temperature for life. Because water resists temperature changes, it stabilizes environments like oceans and lakes, and helps maintain constant body temperatures in organisms (e.g., humans sweat to cool down). |
> ✔ Explanation: Water’s high specific heat is due to hydrogen bonding, which requires extra energy to break. This property makes water excellent at buffering temperature changes.

| Answer: When water freezes, its molecules form a hexagonal lattice structure (ice) held together by hydrogen bonds. This arrangement creates more space between molecules, making ice less dense than liquid water. That’s why ice floats. | *Illustration: Left side shows tightly packed water molecules; right side shows open, hexagonal lattice of ice.* | Answer: Because ice floats, it insulates the water below, preventing lakes and rivers from freezing solid. This allows aquatic life to survive in winter. |
> ✔ Explanation: This unique property is crucial for ecosystems — if ice sank, bodies of water would freeze from bottom to top, killing most aquatic life.

|--------------------------------------------------|-----------|-----------------------------------------------|
| Answer: The man sweating illustrates evaporative cooling. As water (sweat) evaporates from the skin, it absorbs heat from the body, lowering body temperature. This process relies on water’s high heat of vaporization. | *Illustration: A cartoon character sweating with a speech bubble saying “Yikes! We have any way to cool off?”* | Answer: Many organisms use this to regulate body temperature. Sweating in humans, panting in dogs, and transpiration in plants all rely on evaporation of water to cool the organism. |
> ✔ Explanation: Water has a high heat of vaporization due to strong hydrogen bonds — it takes a lot of energy to turn liquid into vapor, so when water evaporates, it removes heat from the surface.

> Question: As mentioned throughout the video, hydrogen bonds are responsible for many of water's properties. Select one of the above properties and explain how hydrogen bonds contribute to the property.
Answer Example (using Specific Heat):
Hydrogen bonds contribute to water’s high specific heat because these bonds must be broken before water molecules can gain kinetic energy and increase in temperature. Since breaking hydrogen bonds requires significant energy, water absorbs a lot of heat without warming up much. This helps stabilize environmental and biological temperatures.
> Alternatively, you could choose:
- Expansion upon freezing: Hydrogen bonds create an open lattice structure in ice, making it less dense.
- Evaporative cooling: Hydrogen bonds require a lot of energy to break during evaporation, allowing water to absorb heat effectively.

| Property | Role of Hydrogen Bonds |
|--------|-------------------------|
| High Specific Heat | Requires energy to break H-bonds → slows temperature rise |
| Expansion Upon Freezing | H-bonds form a rigid, open lattice in ice → lower density |
| Evaporative Cooling | Strong H-bonds mean high energy needed to vaporize → cools surroundings |
---
This worksheet emphasizes how hydrogen bonding gives water unique physical properties essential for life. These include:
- Temperature regulation
- Floating ice protecting aquatic ecosystems
- Cooling mechanisms in organisms
All of these are directly tied to the molecular behavior of water due to hydrogen bonding.
