Explanation:

Hello!

Kinetic Energy (1/2 · mass · velocity²) arises when an object is moving, or when a force acts on it. For example, a moving car demonstrates this principle.

Potential energy (mass · height · gravity) exists when an object has the capacity to perform work. An example would be an item resting on a shelf. It possesses the potential to fall, converting its potential energy into kinetic energy.

-----------------------------------------------------------------------------------------------------------

By examining the examples from the table, we categorize them as follows:

Girl swimming laps- Kinetic energy as the girl is in motion.

Boy standing on diving board - Potential energy since the boy is still but has the potential to move.

Girl striking volleyball - Kinetic energy as the volleyball is actively moving.

Boy grasping volleyball- Potential energy since the volleyball is at rest and can potentially be set in motion.

Thus, the accurate classification is table 1.

Answer:

1. The boy detected an unpleasant odor from the packet that was left out on the table, caused by rancidity.

2. The packet stored in the refrigerator remained odor-free because it was not exposed to air.

Explanation:

Rancidity occurs when fats and oils undergo oxidation, leading to a change in their smell and flavor.

Exposure of food items to oxygen results in oxidation, which produces unpleasant smells and tastes.

Answer:

What does she require from the food consumed and the air inhaled to successfully complete her run?

A. To support her jogging, Rosa needs food that is rich in carbohydrates (like bread). It is not advisable for her to consume protein-rich items just before exercise unless she is following a weight loss regimen.

B. To carry out aerobic respiration, Rosa requires oxygen, which is crucial for maximizing energy release (36 molecules produced per reaction). In contrast, anaerobic reactions produce lesser energy (2 ATP molecules per reaction) and are not ideal.

How do Rosa's body systems collaborate to transport the necessary molecules into her cells?

For her body cells to engage in aerobic respiration and release energy efficiently, they depend on carbohydrates (glucose) and oxygen. These molecules travel through diffusion into the bloodstream. While she jogs, the complex carbs in bread (like starch) break down into simpler glucose molecules, which then diffuse into the blood. Concurrently, increased oxygen is delivered to the cells through faster blood circulation, assisted by the rapid pumping action of the lungs and heart. This collective function ensures both glucose and oxygen are provided to cells, where they are utilized by mitochondria to create ATP energy molecules.

How do hair cells utilize these molecules for energy release allowing her to run?

Once glucose and oxygen enter the bloodstream, they are absorbed into cells, directed to mitochondria which convert them into energy in the form of ATP. Mitochondria are aptly referred to as the cell's powerhouse. Within each cell, energy release occurs in a sequence comprising glycolysis, the Krebs cycle, and oxidative phosphorylation. In this process, glucose reacts with oxygen, ultimately creating 36 ATP molecules per reaction run, sufficient to meet high energy demands. During exercise, both oxygen and glucose are supplied more rapidly due to the accelerated activity of the lungs and heart.

PS: Anaerobic respiration is not able to meet higher energy demands as it yields only 2 ATP per reaction.
