2.

Animals lay _________ or produce babies.

Explanation
Animals lay eggs as a means of reproduction. This is a common method among many species, including birds, reptiles, fish, and some mammals. Eggs provide a protective environment for the developing embryo and allow for external fertilization. The process of laying eggs is crucial for the survival and continuation of many animal species.

3.

Plants breathe through ___________________ in their leaves.

Explanation
Plants have small openings called pores, also known as stomata, on the surface of their leaves. These pores allow for the exchange of gases, including oxygen and carbon dioxide, between the plant and its environment. Through these openings, plants take in carbon dioxide for photosynthesis and release oxygen as a byproduct. Additionally, the pores also help regulate water loss from the plant through transpiration. Therefore, it can be concluded that plants breathe through pores in their leaves.

4.

Animals ______________ in search of food.

Explanation
Animals move in search of food because they need to find sustenance to survive. Moving allows them to explore different areas and habitats where they can find sources of food. Animals have different strategies for finding food, such as hunting, foraging, or scavenging. By constantly moving, animals increase their chances of encountering food resources and meeting their nutritional needs. This behavior is essential for their survival and is a fundamental instinct ingrained in their biology.

Rate this question:

5.

Both plants and animals _________ in size.

Explanation
Plants and animals both undergo a process of growth in size. This growth involves an increase in the number and size of cells, resulting in an overall increase in the size of the organism. This growth is essential for both plants and animals to develop and mature. Therefore, the correct answer is "grow."

_____________________ is a flower that shows movement.

7.

Fish breathe through

Spiracles
Fins
Gills
Lungs

Correct Answer

A. Gills

Explanation

Fish breathe through gills, which are specialized organs that extract oxygen from water. Gills are located on the sides of a fish's head and consist of thin filaments that are rich in blood vessels. As water passes over the gills, oxygen from the water diffuses into the fish's bloodstream, while carbon dioxide is released. This allows fish to extract oxygen from their aquatic environment and is essential for their survival. Unlike lungs, which are used by mammals and some other animals to extract oxygen from the air, gills are specifically adapted for extracting oxygen from water.

__________________ is a characteristic of non - living things.

Movement
Reproduction
Lifeless
Growth

Correct Answer

A. Lifeless

Explanation

The characteristic of "lifeless" refers to non-living things. Non-living things do not possess the ability to move, reproduce, or grow. They lack the essential biological processes that are associated with living organisms. Therefore, "lifeless" is the correct answer as it accurately describes the characteristic of non-living things.

9.

Living things move to _____________________________

Get food
For clothing
For fun

Correct Answer

A. Get food

Explanation

Living things move to get food because food is essential for their survival and to meet their energy requirements. Moving allows them to search for sources of food, such as plants or other animals, and to access different areas where food might be available. Movement also helps living things to avoid predators and competition for limited food resources. Therefore, the ability to move is crucial for living things to ensure their survival and obtain the necessary nutrients for growth and reproduction.

10.

A tree has ____________ to fix itself firmly in the soil

Leaf
Root
Flower
Fruit

Correct Answer

A. Root

Explanation

A tree has roots to fix itself firmly in the soil. Roots play a vital role in anchoring the tree and providing stability. They also absorb water and nutrients from the soil, which are essential for the tree's growth and survival. Without roots, a tree would not be able to stand upright or obtain the necessary resources for its sustenance.

Rate this question:

11.

A seed grows into a small plant is called _________________________

Caterpillar
Kitten
Seedling
Tad pole

Correct Answer

A. Seedling

Explanation

A seedling is the correct answer because it refers to a young plant that has grown from a seed. As the seed begins to germinate and sprout, it develops into a seedling. This stage is characterized by the emergence of leaves and the development of a small root system. The term "seedling" specifically describes the early growth stage of a plant, making it the most appropriate choice among the given options.

Pick Odd one out

Ant
Fish
Frog
Bird
Tree
Stone

Correct Answer

A. Stone

Explanation

The odd one out in this list is "Stone" because it is not a living organism like the other options. Ant, fish, frog, bird, and tree are all living creatures, whereas a stone is an inanimate object.

Rate this question:

13.

Pick the odd one out

Gills
Lungs
Pores
Legs
Air Holes

Correct Answer

A. Legs

Explanation

The odd one out in this list is "Legs" because it is the only option that is not directly related to respiration. Gills, lungs, pores, and air holes are all respiratory organs or structures that organisms use to breathe, while legs are used for locomotion.

Rate this question:

14.

Pick the odd one out

Air
Water
Sun
Table
Mountains

Correct Answer

A. Table

Explanation

The odd one out in this list is "Table" because it is the only item that is not a natural element or phenomenon. Air, water, sun, and mountains are all natural entities, whereas a table is a man-made object.

Rate this question:
