You're hiking in a mountainous region. Suddenly, you slip and fall, twisting your ankle. The pain is intense, and you're unable to put any weight on your foot. How does the skeletal system works in this situation?
The skeletal system plays a crucial role in healing this injury by providing a framework for the damaged tissue to repair itself.
The skeletal system plays a crucial role in healing this injury by providing a framework for the damaged tissue to repair itself and by storing minerals that are necessary for bone healing.
The skeletal system plays a crucial role in healing this injury by spraining the ligaments and produce red blood cells, white blood cells.

One of the roles of the respiratory system is to facilitate gas exchange between the body and the environment. You take a deep breath after sprinting. This is a direct result of how the respiratory system works.
Regulates body temperature that makes our mood happy or sad.
Controls digestion so that we can eliminate our body waste properly.
Filters blood, to maintain good function of the different parts of the body.
Allows for the exchange of oxygen and carbon dioxide in the lungs, to provide oxygenated blood throughout the body.
Which of the following human body systems contains the heart and the blood vessels and moves blood throughout the body.
A. Circulatory system
B. Digestive system
C. Respiratory system
D. Skeletal system
Visualize creating a simple flowchart to show the path food takes through the digestive system. Which of the following best represents the correct sequence of steps you should include in your flowchart?
Food is chewed in the mouth → Moves to the stomach → Travels to the small intestine → Passes into the large intestine → Leaves the body as waste.

A farmer in San Isidro plants mango trees in his farm. He notices that the roots of the mango tree are strong and extend deep into the soil. Why are the roots important for the tree?
The roots help the tree absorb water and nutrients from the soil.
The roots help the tree produce fruits.
The roots make the leaves greener.
The roots make the tree taller.
In a science experiment, learners in General Santos City compared two plants: one with roots cut off and one with roots intact. After one week, the plant without roots begins to wilt. What is the most likely reason for this?
The plant could not absorb water and nutrients from the soil.
The plant could not get enough sunlight.
The plant lost its ability to produce flowers.
The plant's leaves stopped growing.
A farmer notices that a certain type of plant thrives in the rice fields in Buayan, where the area is often flooded. Based on this information, how should the farmer classify this plant?
A. Aerial
B. Aquatic
C. Desert
D. Terrestrial
You are a young biologist exploring the lush jungles of General Santos City, Philippines. As you trek deeper into the forest, you encounter various plants and animals. Your task is to classify these organisms based on their habitat. Which of the following animals is most likely to be found in the canopy of the rainforest?
Dugong
Philippine eagle
Philippine crocodile
Tarsier
You are visiting a fishing village and see different kinds of animals. One of the animals is a bat hanging from a tree. How should this bat be classified based on its habitat?
Aerial
Aquatic
Desert
Terrestrial
A Grade 4 learner from Francisco Oringo Sr. ES observes the shoot system of a coconut tree. Which of the following best explains the importance of the shoot system for the plant?
It helps the tree absorb water from the soil.
It helps the tree grow taller quickly.
It stores food for the tree to grow.
It supports the plant and allows the leaves to capture sunlight for photosynthesis.
Why is it important to study animals and plants in their specific habitats?
To develop new medicines and treatments.
To identify new species and classify them.
To understand how animals and plants adapt to different environments.
All of the above.
In a garden habitat, you notice that caterpillars are feeding on the leaves of plants. After a few days, you see fewer caterpillars and more butterflies. What does this observation tell you about the life cycle of the caterpillar?
The butterflies chased away the caterpillars.
The caterpillars are still there but hiding from the butterflies.
The caterpillars have eaten all the leaves and moved to a new place.
The caterpillars turned into butterflies after completing their life cycle.
A butterfly's life cycle is a fascinating journey that involves four distinct stages. Which of the following is the correct order of stages in a butterfly's life cycle?
Adult, egg, caterpillar, pupa
Caterpillar, egg, pupa, adult
Egg, caterpillar, pupa, adult
Pupa, egg, caterpillar, adult
A community near the seashore observes that fewer fish are being caught in their area. Based on your knowledge of food chains, what could be the most likely reason for this?
More fishermen are catching all the fish before they grow.
There are fewer small fish for bigger fish to eat, possibly due to overfishing.
The fish have moved closer to the shore to avoid bigger predators.
The plants growing on the seashore are taking up too much space.
In a mangrove swamp, crabs and fish thrive in the water, while some birds live in the trees. What will most likely happen if many of the mangrove trees are cut down?
Crabs will thrive as there will be fewer birds to eat them.
More plants will grow in the swamp to replace the mangroves.
The fish population will increase because they have more space to swim.
The entire food chain could be affected, and the animals might lose their habitat.
