1.
What nutrient group gives long-lasting energy?
Correct Answer
C. Fats
Explanation
Fats provide long-lasting energy because they are a concentrated source of calories. When consumed, fats are broken down into fatty acids, which are then used by the body as a source of fuel. Unlike carbohydrates, which are quickly burned for energy, fats are metabolized slowly, providing a sustained release of energy over a longer period of time. This makes them an important nutrient group for activities that require endurance and prolonged energy, such as long-distance running or hiking.
2.
Which digestive organ sends the broken-down nutrients out to the body?
Correct Answer
B. Small Intestine
Explanation
The small intestine is responsible for absorbing and sending the broken-down nutrients from food into the bloodstream, which then distributes them to the rest of the body. It is the longest part of the digestive system and has a large surface area for maximum absorption. The stomach breaks down food into smaller pieces, but it is the small intestine that actually absorbs the nutrients. The large intestine mainly absorbs water and electrolytes, while the liver produces bile to aid in digestion but does not directly send nutrients out to the body.
3.
Which of these is a deep-sea creature?

Explanation
Aristotle categorized plants based on their growth habits, and one of the categories he identified was "shrubs." Shrubs are woody plants that are smaller than trees and have multiple stems arising from the base. They are characterized by their bushy appearance and are often found in gardens and landscapes. Aristotle's classification system aimed to organize and understand the natural world, including plants, based on their observable characteristics.
7.
Which of the following is an example of a nonvascular plant?
Correct Answer
D. Moss
Explanation
Moss is an example of a nonvascular plant because it lacks specialized tissues for transporting water and nutrients. Nonvascular plants, also known as bryophytes, rely on direct absorption of water and nutrients from their surroundings. Mosses are small, simple plants that typically grow in moist environments. They do not have true roots, stems, or leaves, and instead have simple structures that allow them to absorb water and nutrients directly from their environment.
8.
Which of the following mimics a monarch butterfly?
Correct Answer
D. Viceroy
Explanation
The Viceroy butterfly mimics a monarch butterfly. This is because the Viceroy has similar bright orange and black coloration, as well as similar wing patterns, to the monarch butterfly. This mimicry is a form of protection, as predators often mistake the Viceroy for the toxic monarch butterfly and avoid eating it. This adaptation helps the Viceroy butterfly survive and avoid predation.
9.
What is the average natural lifespan of an African elephant?
Correct Answer
D. 55 Years
Explanation
The average natural lifespan of an African elephant is 55 years. African elephants are known to live longer compared to other elephant species. They have a relatively long lifespan due to their large size, strong social bonds, and relatively low predation rates. These factors contribute to their ability to survive and thrive in their natural habitat for an extended period of time.
10.
What type of plant is a carrot?
Correct Answer
C. Biennial
Explanation
A carrot is classified as a biennial plant. This means that it completes its life cycle in two years. In the first year, the carrot plant grows leaves, stems, and roots. In the second year, it produces flowers and seeds before dying. Carrots are typically harvested during the first year when the roots are mature and edible.
11.
Which of these animals goes through incomplete metamorphosis?
Correct Answer
D. Grasshopper
Explanation
Grasshoppers go through incomplete metamorphosis, which means they do not have a distinct larval stage like butterflies or beetles. Instead, grasshoppers hatch from eggs as nymphs and resemble miniature versions of the adult grasshopper. As they grow, they molt several times, shedding their exoskeleton and developing wings and reproductive organs. Eventually, they reach adulthood without undergoing a complete transformation. This is in contrast to butterflies, which undergo a complete metamorphosis from egg to larva (caterpillar), pupa (chrysalis), and adult butterfly.
12.
What is the second stage of incomplete metamorphosis called?
Correct Answer
D. NympH
Explanation
The second stage of incomplete metamorphosis is called the nymph stage. In this stage, the insect hatches from an egg and resembles a smaller version of the adult, but without wings. The nymph undergoes a series of molts, shedding its exoskeleton and growing larger each time. Eventually, it reaches its final molt and emerges as a fully developed adult. This stage is characteristic of insects such as grasshoppers, dragonflies, and cockroaches.
13.
What word means "terrible lizard"?

Dinosaurs were a group of reptiles that lived millions of years ago and are now extinct. They were known for their large size and dominant presence on Earth during the Mesozoic Era.
14.
How many main kingdoms are there in the living world?
Correct Answer
D. Five
Explanation
There are five main kingdoms in the living world. This implies that the question is referring to the classification of living organisms into five broad categories, namely Animalia, Plantae, Fungi, Protista, and Monera. These kingdoms are based on the fundamental characteristics and traits of organisms, helping to categorize and understand the diversity of life on Earth.
15.
Which of the following is the largest group directly under kingdoms?
Correct Answer
D. pHylum
Explanation
Phylum is the largest group directly under kingdoms in the classification system. The classification system starts with the highest level, which is the kingdom, and then progresses down to smaller and more specific groups. Phylum is the level immediately below kingdom and represents a large group of organisms that share certain characteristics. It is followed by class, genus, and species, which are progressively more specific categories. Therefore, phylum is the correct answer as it is the largest group directly under kingdoms.
16.
What color is a polar bear's skin?
Correct Answer
B. Black
Explanation
Polar bears actually have black skin, despite their white fur. The black skin helps them to absorb and retain heat from the sun, keeping them warm in their icy habitat. The fur appears white because it is translucent and reflects light. This camouflage allows polar bears to blend in with the snow and ice, making them effective hunters.
17.
What is the primary diet of sperm whales?
Correct Answer
C. Squid
Explanation
Sperm whales primarily feed on squid. They have a unique hunting strategy where they dive deep into the ocean to hunt for their prey. Sperm whales have specialized teeth and a large mouth that allows them to capture and consume large quantities of squid. They are known to consume several species of squid, including giant squid, which can be as long as the sperm whale itself. This diet of squid provides the sperm whale with the necessary nutrients and energy to survive and thrive in their ocean habitat.

How fast can the peregrine falcon go in a dive?
Correct Answer
C. 200 Miles Per Hour
Explanation
The peregrine falcon can reach speeds of up to 200 miles per hour in a dive. This incredible speed makes it the fastest bird in the world and one of the fastest animals on the planet. The falcon achieves this speed by tucking its wings and adopting a streamlined shape, allowing it to dive with incredible precision and power. This high-speed dive is crucial for the falcon when hunting, as it enables it to quickly and accurately capture its prey in mid-air.
20.
What is another name for an ant cow?
Correct Answer
D. ApHid
Explanation
An ant cow is another name for an aphid. Aphids are small, soft-bodied insects that are often found in colonies on plants. They are called ant cows because they produce a sugary substance called honeydew, which ants feed on. This symbiotic relationship between ants and aphids is similar to the relationship between humans and cows, where humans benefit from the milk produced by cows. Therefore, aphid is the correct answer for another name for an ant cow.
