Wee Beasties- Before And After Test

Food, shelter, clothing, and love are considered the four basic needs of humans. These needs are essential for human survival and well-being. Food provides the necessary nutrients and energy for the body, shelter protects individuals from the elements and provides a safe space, clothing offers protection and comfort, and love fulfills emotional and social needs. These four needs are fundamental for human existence and are universally recognized as essential for a healthy and fulfilling life.

Scientists use a microscope to examine really small objects. A microscope is a tool that uses lenses and light to magnify and visualize objects that are too small to be seen with the naked eye. It allows scientists to study the details and structures of microscopic organisms, cells, and particles, enabling them to make observations and conduct research in various scientific fields such as biology, medicine, and chemistry. An overhead projector, a hand lens, and a pair of glasses are not suitable tools for examining really small objects.

The correct answer is "an organism" because it is the term used to describe a living thing. It encompasses all living entities, including plants, animals, and microorganisms. "Cytoplasm" refers to the jelly-like substance inside cells, "prey" refers to an animal that is hunted and killed by another for food, and "metamorphic" refers to a process of transformation or change.

The correct answer is "make something appear larger." When you magnify something, you are increasing its size or scale, making it appear bigger than it actually is. This can be done using tools such as magnifying glasses, microscopes, or zoom functions on digital devices. Magnification is commonly used in various fields, such as science, photography, and technology, to enhance visibility and details of objects or images.

The correct answer is sunflower, ladybug, and sea sponge. These three options are living things because they exhibit characteristics of life such as growth, reproduction, and response to stimuli. Plastic wrap, kitchen sponge, star, sun, static electricity, cotton, water, coral, and seaweed are not living things as they do not possess these characteristics.

Green plants have the unique ability to perform photosynthesis, a process where they convert sunlight, water, and carbon dioxide into glucose (sugar) and oxygen. This ability allows them to create their own food from sunlight, which is not possible for animals. Animals, on the other hand, rely on consuming other organisms for their nutritional needs. Therefore, the correct answer is "create their own food from sunlight".

To focus means to make something appear clearer. When we focus on something, we bring it into sharp and clear focus, allowing us to see it more clearly. This can be done by adjusting the lens of a camera or the focus of our eyes. By focusing, we enhance the clarity and detail of the object or subject we are looking at, making it easier to perceive and understand.

A living thing made of more than one cell is called multi-cellular because "multi" means many or more than one, and "cellular" refers to cells. Therefore, the term "multi-cellular" accurately describes an organism that is composed of multiple cells.

When a brown mouse and a white mouse mate, their children can inherit different combinations of genes from their parents. If the brown mouse is homozygous dominant (BB) and the white mouse is homozygous recessive (bb), then all of their offspring will be brown heterozygous (Bb). This would result in all four children being brown. However, if the brown mouse is heterozygous (Bb) and the white mouse is homozygous recessive (bb), then there is a 50% chance that each offspring will inherit the recessive white gene from the white mouse. This would result in three brown offspring and one white offspring. Therefore, both scenarios are possible.

A cell is the basic unit of structure and function of all living things. It is the smallest unit of life that can perform all the necessary functions of an organism, such as metabolism, reproduction, and response to stimuli. Cells are the building blocks of life, as they can combine to form tissues, organs, and ultimately entire organisms. The other options, such as nucleus and atom, are not the correct answers as they do not encompass the entirety of a living organism's structure and function.

The three basic parts of a plant are leaves, stem, and roots. Leaves are responsible for photosynthesis, where plants convert sunlight into energy. The stem provides support for the plant and transports water, nutrients, and sugars between the roots and leaves. Roots anchor the plant in the ground and absorb water and nutrients from the soil. These three parts are essential for the survival and growth of a plant.

A compound microscope is an instrument that uses two lenses or more to magnify an object. This type of microscope is commonly used in scientific research and laboratory settings. It provides higher magnification and resolution compared to a simple microscope or a hand lens. A graduated cylinder, on the other hand, is a cylindrical container used for measuring liquid volume and is not related to magnifying objects.

A lens is a piece of clear material that can bend or refract light rays as they pass through it. It is used in various optical devices such as cameras, telescopes, and eyeglasses to focus or diverge light. Unlike a laser, which amplifies and emits a narrow beam of light, a lens is primarily used for manipulating the path of light. A microscope is an optical instrument that uses lenses to magnify small objects, while a cell is a basic unit of life and not related to the bending or refracting of light.

All living things need to get rid of body waste in order to maintain their health and survival. This process is essential for removing toxins and waste products from the body, ensuring that the internal environment remains balanced and functional. Failure to eliminate waste can lead to the buildup of harmful substances, which can be detrimental to an organism's overall well-being. Therefore, getting rid of body waste is a crucial way for all living things to meet their basic needs and stay alive.
