1.
Which one of these is not part of the scientific method?
Correct Answer
B. Intelligence
Explanation
Intelligence is not part of the scientific method because the scientific method is a systematic approach to acquiring knowledge through observation, experimentation, and drawing conclusions based on evidence. Intelligence refers to the ability to acquire and apply knowledge, whereas the scientific method is a specific process used to generate and test hypotheses in order to gain understanding of the natural world.
2.
Which of these animals does not undergo metamorphosis?
Correct Answer
A. Human
Explanation
Humans do not undergo metamorphosis. Metamorphosis refers to the process of transformation from an immature form to an adult form in insects and amphibians. While insects like the Monarch Butterfly and Beetle, as well as amphibians like the Frog, go through distinct stages of development during metamorphosis, humans do not experience such a transformation. Instead, humans grow and develop through a gradual process of physical and cognitive changes over time.
3.
Which of these is not a plant?
Correct Answer
D. Marsh Hawk
Explanation
A marsh hawk is not a plant because it is a type of bird. It belongs to the species of hawks that are commonly found in marshy areas. Unlike plants, hawks are animals that belong to the animal kingdom. They have wings, feathers, and are capable of flying. Therefore, the marsh hawk does not fit the category of a plant.
4.
Which of these is not a learned trait?
Correct Answer
C. Brown Eyes
Explanation
Brown eyes are not a learned trait because they are determined by genetics. The color of a person's eyes is determined by the amount and type of melanin in the iris, which is determined by the genes inherited from their parents. It is not something that can be learned or acquired through experience or behavior. Therefore, brown eyes do not fall under the category of learned traits.
5.
Which of these is found only on Earth?
Correct Answer
B. Living Creatures
Explanation
Living creatures are found only on Earth because they are a product of the unique conditions and environment that exist on our planet. Mountains, volcanoes, and meteorites can be found on other celestial bodies such as the Moon, Mars, and other planets. However, the presence of living creatures, with their complex biological systems and diverse forms of life, is exclusive to Earth. This is due to a combination of factors including the presence of liquid water, a suitable atmosphere, and the right temperature range that supports life as we know it.
6.
How many legs do insects have?
Correct Answer
C. 6
Explanation
Insects typically have six legs. This is a characteristic feature of insects that distinguishes them from other animals. Having six legs allows insects to move efficiently and perform various functions such as walking, climbing, and jumping. The presence of six legs is a defining trait of the insect class, making option 6 the correct answer.
7.
Which of these is not an insect?
Correct Answer
D. Black Widow Spider
Explanation
The black widow spider is not an insect because it belongs to the class Arachnida, while insects belong to the class Insecta. Insects have six legs, three body segments, and typically have wings, while spiders have eight legs and two body segments. Therefore, the black widow spider does not meet the criteria to be classified as an insect.
8.
Which habitat would a fresh water fish live in?
Correct Answer
C. Lake Erie
Explanation
Freshwater fish are adapted to live in bodies of water that have a low salt content, such as lakes, rivers, and ponds. Lake Erie is a freshwater lake located in North America, specifically between the United States and Canada. Therefore, it is a suitable habitat for freshwater fish to live in. The Atlantic and Pacific are both saltwater bodies of water, while the Himalayas are mountains and not a suitable habitat for fish.
9.
What part of the plant does most of the photosynthesis?
Correct Answer
B. Leaf
Explanation
Photosynthesis is the process by which plants convert sunlight into energy. The leaf is the primary site of photosynthesis in plants. It contains specialized cells called chloroplasts that contain chlorophyll, the pigment responsible for capturing sunlight. These chloroplasts absorb light energy and use it to convert carbon dioxide and water into glucose and oxygen. The leaf's large surface area and thin structure allow for maximum exposure to sunlight, making it the main location for photosynthesis in plants.
10.
What is the name of the scientific tool used to view the smallest parts of things?
Correct Answer
D. Microscope
Explanation
A microscope is a scientific tool used to view the smallest parts of things. It is specifically designed to magnify objects that are too small to be seen with the naked eye. By using lenses and light, a microscope allows scientists to examine and study microscopic organisms, cells, and other tiny structures. This tool has revolutionized the field of biology and has contributed significantly to our understanding of the microscopic world.
11.
Which of these living creatures does not belong in the same group?
Correct Answer
B. Scorpion
Explanation
The honeybee, praying mantis, and housefly all belong to the same group of insects, as they all have six legs and belong to the class Insecta. However, the scorpion does not belong to this group as it is not an insect. Scorpions belong to the class Arachnida, along with spiders and ticks, and they have eight legs.
12.
Which state of matter is an ice cube?
Correct Answer
D. Solid
Explanation
An ice cube is a solid state of matter because it has a definite shape and volume. In the solid state, the particles are tightly packed together and vibrate in fixed positions. The molecules in an ice cube are held together by strong intermolecular forces, causing them to maintain a rigid structure.
13.
What is the theory that describes how the continents got where they are today?
Correct Answer
A. Continental Drift Theory
Explanation
The correct answer is Continental Drift Theory. This theory, proposed by Alfred Wegener in the early 20th century, explains that the Earth's continents were once joined together in a single landmass called Pangaea and have since drifted apart over millions of years. This movement is believed to be caused by the slow movement of tectonic plates on the Earth's surface. The theory is supported by evidence such as the fit of the continents, the distribution of fossils and rock formations, and the matching geological features across different continents.
14.
Which of these is a parasitic relationship?
Correct Answer
B. A Flea On A Dog
Explanation
A parasitic relationship is a type of symbiotic relationship where one organism benefits at the expense of another organism, known as the host. In the case of a flea on a dog, the flea is the parasite and the dog is the host. The flea feeds on the dog's blood, causing irritation and potential health issues for the dog. The flea benefits from this relationship by obtaining nourishment, while the dog is harmed. This demonstrates a clear example of a parasitic relationship.
15.
Which of these is a feature of the cardiovascular system of the human body?
Correct Answer
C. Heart
Explanation
The cardiovascular system of the human body is responsible for pumping and circulating blood throughout the body. The heart, which is the correct answer, is the main organ of the cardiovascular system. It is a muscular organ that contracts and relaxes to pump blood, providing oxygen and nutrients to the body's tissues and organs. The heart also helps to remove waste products from the body. Without the heart, the cardiovascular system would not be able to function properly, leading to serious health issues.
