How Well Do You Recall Basic Biology? Quiz

A dog is a common choice for guarding a house because they are naturally protective and loyal to their owners. They have a strong sense of hearing and smell, which makes them excellent at detecting intruders or unusual activity. Dogs can be trained to bark or alert their owners when someone approaches the house, which can act as a deterrent to potential burglars. Additionally, some dog breeds are known for their territorial instincts and are more likely to defend their home and family if necessary.

Eggs are the product we get from chickens. Chickens are known for laying eggs, which are commonly consumed as a food product. Eggs are a rich source of protein and are used in various culinary preparations. They can be cooked in different ways and are a versatile ingredient in many dishes. Therefore, eggs are the correct product obtained from chickens.

The correct answer is polar bear because polar bears are known to live in the Arctic region, where there is snow and ice. They are well adapted to the cold climate and are excellent swimmers, making them perfectly suited for their icy habitat.

Horses are commonly used to pull carts due to their size, strength, and ability to be trained for such tasks. They have a long history of being used as working animals and are known for their pulling power. Their large size and muscular build make them well-suited for pulling heavy loads, such as carts or carriages. Additionally, horses have been selectively bred for centuries to enhance their pulling abilities, making them the ideal choice for this task.

Malaria is a disease caused by a parasite that is transmitted to humans through the bites of infected female Anopheles mosquitoes. These mosquitoes become infected with the parasite when they bite an infected person and then transmit it to the next person they bite. Other insects like cockroaches and termites do not transmit malaria, making the correct answer "mosquito".

Fish breathe through gills and lay eggs, which are characteristics unique to them. While birds, mammals, and dogs all breathe through lungs, fish have adapted to live in water and extract oxygen from it through their gills. Additionally, fish are oviparous, meaning they lay eggs, while birds, mammals, and dogs give birth to live young. Therefore, the correct answer is fish.

Male peacocks have fantastic feathers which they display to females as a part of their courtship behavior. These feathers, known as a peacock's train, are vibrant and colorful, and they are used to attract the attention of female peahens. The display of these feathers is a visually striking spectacle, and it plays a crucial role in the peacock's mating rituals. The feathers are often fanned out and displayed in a way that showcases their beauty and grandeur, making the male peacock a remarkable sight to behold.

Invertebrates are animals that don't have a backbone. This means that they lack a vertebral column, which is the defining characteristic of vertebrates. Invertebrates make up the majority of animal species on Earth and include creatures such as insects, spiders, worms, and mollusks. These animals have evolved different structural adaptations to support their bodies and perform various functions without the need for a rigid backbone.

Flour is the correct answer because it is commonly made by grinding seeds, grains, or roots. It is a key ingredient in baking bread as it provides structure and texture to the final product. Butter is a dairy product and not made from grinding seeds. Medicine and rice are not directly related to the process of grinding seeds for baking bread.

Parasites are organisms that live on or inside another organism (host) and obtain nutrients from the host, often causing harm to the host's body. They can include various types of animals, such as fleas, ticks, lice, and worms, that can cause diseases or discomfort in humans. Therefore, parasites are the correct term to describe animals that live on human bodies and can harm the body.

Oranges can be used to make a drink because they are a citrus fruit that is rich in vitamin C and has a refreshing and tangy flavor. Oranges can be juiced to make orange juice, which is a popular and commonly consumed beverage. Additionally, oranges can be used in smoothies, cocktails, and other fruit-based drinks.

When a baby bird opens its mouth to be fed without being taught, it is displaying instinctive behavior. Instinctive behavior refers to innate actions that animals perform without prior learning or experience. In this case, the baby bird's instinct prompts it to open its mouth when it sees its parent approaching with food. This behavior is not learned but rather a natural response that aids in survival and development.

Nectar is a sweet sticky substance that some flowers produce to attract insects and birds. It serves as a reward for these pollinators, who then help in the transfer of pollen from one flower to another, aiding in the process of fertilization. Nectar is an important adaptation that helps ensure the successful reproduction of flowering plants.

A frog is classified as an amphibian because it is a vertebrate animal that can live both on land and in water. Amphibians are characterized by their ability to breathe through both lungs and their skin, as well as their unique life cycle that involves a larval stage (tadpole) and an adult stage. Unlike mammals and reptiles, frogs do not have hair or scales, and they lay eggs instead of giving birth to live young. Therefore, the correct answer is amphibian.

The correct answer is "Amphibians can live on land and in water." This statement is true because amphibians are a group of animals that have the ability to live both on land and in water. They have adaptations that allow them to survive in both environments, such as lungs for breathing on land and gills for breathing in water. Examples of amphibians include frogs, toads, and salamanders.

Crops refer to the plants that are cultivated and harvested for various purposes, including consumption and sale. They are specifically grown for their yield, such as fruits, vegetables, grains, and other agricultural products. The term "crops" encompasses a wide range of plants that are cultivated on farms and play a crucial role in providing food and resources for human consumption and economic purposes.

Animals can be taught certain behaviors, such as sitting or coming when called. These behaviors are not instinctive, meaning they are not naturally occurring or inherent in the animal's nature. Instead, they are learned through training and conditioning. Therefore, the correct answer is "learned."

Goldfish can be kept as a pet because they are small, low-maintenance, and can adapt well to living in a fish tank or aquarium. They are popular pets for beginners and children due to their vibrant colors and peaceful nature. Unlike larger animals like camels or crocodiles, goldfish require less space, food, and attention, making them suitable for keeping in a home environment.

The ostrich is not an invertebrate because it is a bird and birds are vertebrates. Invertebrates are animals that do not have a backbone or vertebral column, while vertebrates have a backbone. Slugs and worms, on the other hand, are invertebrates as they do not possess a backbone. Therefore, the correct answer is ostrich.

Most grasses have fibrous roots. Fibrous roots are a type of root system where the roots are thin, branching, and spread out in all directions. This type of root system allows grasses to anchor themselves firmly in the soil and absorb water and nutrients efficiently. The fibrous roots also help prevent soil erosion by holding the soil together. This is why most grasses, such as lawn grasses, have fibrous roots.

The correct answer is ovary. The ovary is the part of the flower that contains the ovules. The ovules are the structures that develop into seeds after fertilization. The ovary is located at the base of the flower and is typically swollen and enlarged. It plays a crucial role in the reproduction of flowering plants by protecting and nourishing the ovules.

An invertebrate is an animal that does not have a backbone or a spinal column. In this case, a spider is the only option that is an invertebrate as it belongs to the arachnid family, which lacks a backbone. Fish, frog, and dog are all vertebrates as they possess a backbone.

Flowers in plants play a crucial role in reproduction. They contain the reproductive organs, including the male stamen and the female pistil. The stamen produces pollen, which is transferred to the pistil for fertilization. Flowers also attract pollinators like bees, butterflies, and birds through their bright colors and sweet fragrances, aiding in pollination. Once fertilization occurs, flowers develop seeds that can be dispersed to new locations for germination and growth. Therefore, flowers are essential for the reproduction of plants.

A KEY is a chart you can use to identify living things by answering yes or no. This means that the chart consists of a series of questions, and based on the answer to each question, you either move to the next question or identify the living thing. By answering yes or no to the questions in the chart, you can narrow down the possibilities and ultimately determine the identity of the living thing.

Conifer trees are a type of non-flowering plant that reproduce through cones. They are characterized by their needle-like leaves and produce seeds in cones rather than flowers. This makes them different from moss and fern, which are also non-flowering plants but do not produce cones. Therefore, the correct answer is conifer tree.

Mosses and ferns are examples of non-flowering plants because they do not produce flowers for reproduction. Instead, they reproduce through spores. Flowering plants, on the other hand, reproduce through flowers and seeds. Fungi are a separate kingdom of organisms that include mushrooms and yeasts. Herbs, on the other hand, are a type of plant that is known for its soft, non-woody stems.

Melon is classified as a creeping plant because it has long, trailing stems that spread along the ground. Creeping plants typically have a low, spreading growth habit and often produce runners or vines that allow them to spread and cover a larger area. Melons, such as watermelons and cantaloupes, have a vining growth habit and produce long, trailing stems that creep along the soil surface. This allows the plant to take up more space and access sunlight, nutrients, and water from a larger area. Therefore, melon is an example of a creeping plant.

Leaves are the correct answer because they contain chlorophyll, which is necessary for photosynthesis. During photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose, which is their source of food. The process takes place in the leaves, making them the food factories of the plant.

When a fruit is ripe, it means that the seeds inside it have developed fully and are ready to be spread or dispersed away from the parent plant. This dispersal is essential for the survival and propagation of plant species. Pollination refers to the transfer of pollen from the male to the female reproductive organs of a plant, which is different from seed dispersal. Germination is the process by which a seed begins to grow into a new plant, and fertilization is the fusion of male and female gametes to form a zygote. Therefore, the correct answer is dispersal.

The snake is not an invertebrate because it belongs to the reptile group, which includes animals with backbones or vertebrates. In contrast, worms and snails are invertebrates as they do not possess a backbone. Therefore, the snake is the correct answer as it is the only option that is not an invertebrate.
