- Being able to change skin color according to the conditions of the surrounding environment is called ….
- autotomy
- mimicry
- adaptation
- protection
Correct Answer
C. Mimicry
Explanation
Mimicry refers to the ability of an organism to change its skin color according to the conditions of the surrounding environment. This adaptation allows the organism to blend in with its surroundings and provides protection from predators.
2.
Some types of lizards have the ability to sever their tails, this is known as ….
Correct Answer
D. Autotomy
Explanation
Autotomy refers to the ability of certain lizards to voluntarily detach or sever their tails as a defense mechanism. When threatened or attacked, the lizard can shed its tail, which continues to wiggle and distract the predator while the lizard escapes. This adaptation helps protect the lizard from being captured or injured. Therefore, autotomy is the correct answer to the question.
3.
Invertebrates and vertebrates are classifications of animals based on whether they have .... or not.
Correct Answer
C. Spines
Explanation
Invertebrates and vertebrates are classifications of animals based on whether they have spines or not. Invertebrates are animals that do not have a spine or backbone, such as insects, worms, and jellyfish. Vertebrates, on the other hand, are animals that have a spine or backbone, including mammals, birds, reptiles, amphibians, and fish. The presence or absence of spines is a key characteristic used to differentiate between these two major groups of animals.
4.
Carnivores, herbivores, and omnivores are classifications of animals based on ....
Correct Answer
C. Their food
Explanation
The classifications of animals as carnivores, herbivores, and omnivores are based on their food preferences. Carnivores primarily eat meat, herbivores primarily eat plants, and omnivores eat both meat and plants. This categorization is determined by the animals' diet and feeding habits, making "their food" the correct answer.
5.
The part of a rabbit's body that really helps to detect predators is ....
Correct Answer
D. Ears
Explanation
Rabbits have highly developed hearing abilities, and their large, upright ears play a crucial role in detecting predators. The ears are not only sensitive to a wide range of sounds but can also rotate independently, allowing rabbits to locate the source of the sound accurately. This helps them stay alert and aware of potential dangers in their surroundings, enabling them to take quick action and escape from predators.
6.
The part of an eagle’s body that really helps in hunting the prey is ….
Correct Answer
D. Beak and claws
Explanation
The beak and claws of an eagle are both essential for hunting prey. The beak is sharp and powerful, allowing the eagle to tear into its prey and rip it apart. The claws, or talons, are strong and sharp, enabling the eagle to grasp and hold onto its prey securely. Together, the beak and claws provide the eagle with the necessary tools to catch and kill its prey effectively.
7.
What a squid will do when it is threatened is ...
Correct Answer
D. Spray kind of ink
Explanation
When a squid is threatened, it will spray a kind of ink as a defense mechanism. This ink serves to create a cloud in the water, which confuses and distracts the predator, allowing the squid to escape. By releasing this ink, the squid is able to create a diversion and increase its chances of survival.
8.
There are several reptiles and amphibians have in common, one of which can live on land and in water. But one thing that most distinguishes between reptiles and amphibians is ....
Correct Answer
D. The scales
Explanation
One thing that most distinguishes between reptiles and amphibians is the scales. While both reptiles and amphibians can live on land and in water, reptiles have scales, which provide a protective covering for their bodies. Amphibians, on the other hand, have smooth, moist skin. This difference in skin texture is a key characteristic that sets reptiles and amphibians apart from each other.
9.
A change or the process of change by which an organism or species becomes better suited to its environment is known as …
Correct Answer
D. Adaptation
Explanation
Adaptation refers to the process of change in an organism or species that allows it to become better suited to its environment. This change can occur in physical traits, behaviors, or physiological processes, enabling the organism to survive and reproduce more effectively. Adaptation is a fundamental concept in evolutionary biology, as it is through this process that species are able to evolve and thrive in their specific habitats.
10.
A change of the form or nature of a thing or person into a completely different one, by natural or supernatural means is known as …
Correct Answer
A. MetamorpHosis
Explanation
Metamorphosis refers to the process of transformation or change in form or nature. It can occur in both living organisms and non-living objects. This change is often drastic and results in a completely different entity. Metamorphosis can be natural, such as the transformation of a caterpillar into a butterfly, or supernatural, as in the case of mythical creatures. It is distinct from photosynthesis, which is the process by which plants convert sunlight into energy, camouflage, which is a method of blending in with the surroundings for protection, and adaptation, which refers to the adjustment of an organism to its environment.
11.
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water is known as …
Correct Answer
B. pHotosynthesis
Explanation
Photosynthesis is the correct answer because it refers to the process in which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose (food) and release oxygen as a byproduct. This process is essential for the survival of plants and the production of oxygen in the atmosphere. Adaptation, metamorphosis, and camouflage are unrelated terms that do not describe the process of synthesizing food through sunlight.
12.
Roots which grow close to the surface of soil is called …
Correct Answer
B. Fibrous roots
Explanation
Fibrous roots are a type of root system where the roots are thin, numerous, and spread out close to the surface of the soil. These roots do not have a main central root (taproot) but instead form a dense network of roots that provide stability and absorb nutrients from the top layer of the soil. This type of root system is commonly found in grasses and other herbaceous plants. Aerial roots, on the other hand, are roots that grow above the ground, while hanging roots are roots that hang down from the plant.
13.
Roots which is long and the points straight down from the stem of the plant is called …
Correct Answer
D. Taproots
Explanation
Taproots are long and straight roots that grow vertically downwards from the stem of a plant. They are typically thick and provide strong anchorage to the plant. Taproots also have the ability to penetrate deep into the soil, allowing the plant to access water and nutrients from lower soil layers. This type of root system is commonly found in dicotyledonous plants and is advantageous in dry or arid conditions as it helps the plant to obtain water from deeper soil layers.
14.
Plants or trees which have aerial roots, such as …
Correct Answer
A. Orchid, banyan, mangrove
Explanation
Plants or trees such as orchids, banyans, and mangroves have aerial roots. These types of roots are specialized structures that grow above the ground and help the plant obtain oxygen and nutrients. Orchids, banyans, and mangroves are known for their ability to grow and thrive in unique environments, such as rainforests and coastal areas, where aerial roots are beneficial for their survival.
15.

- weeds, sugar cane, pine tree
- grasses, coconut tree, weeds
- sugar cane, teak tree, palm tree
sugar cane, weeds, grasses
Correct Answer
D. Sugar cane, weeds, grasses
Explanation
The correct answer is sugar cane, weeds, grasses. This is because the question is asking for plants with non-woody stems, and out of the given options, sugar cane, weeds, and grasses all have non-woody stems.
