Correct Answer

A. The four basic needs of humans

Explanation

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.

What tool do scientists use to examine really small objects?

an overhead projector
a hand lens
A microscope
A pair of glasses

Correct Answer

A. A microscope

Explanation

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.

Which of the following is one way all living things meet their basic needs to stay alive?

Move from one place to another by walking
Sleep when they’re tired.
Get rid of body waste.
None of the above.

Correct Answer

A. Get rid of body waste.

Explanation

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.

Green plants can do something that animals cannot. Write the letter of the correct choice in the blank.

Grow a foot in one day
create their own food from sunlight
Lose body parts and stay alive
Hibernate

Correct Answer

A. create their own food from sunlight

Explanation

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".

The basic unit of structure and function of all living things is called a(n)

Building block.
Cell
Nucleus
Atom

Correct Answer

A. Cell

Explanation

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.

To magnify means to

make something appear clearer.
make something appear larger.
make something appear smaller.
Make something appear blurry.

Correct Answer

A. make something appear larger.

Explanation

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.

To focus means to

Make something appear clearer.
make something appear larger.
make something appear smaller.
Make something appear blurry.

Correct Answer

A. Make something appear clearer.

Explanation

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 is called

An organism.
A cytoplasm.
a prey.
metamorphic.

Correct Answer

A. An organism.

Explanation

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.

A piece of clear material that bends or refracts light rays passing through it is a

Laser.
Microscope.
Lens.
Cell.

Correct Answer

A. Lens.

Explanation

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.

An instrument which uses two lenses or more for magnifying an object is

A compound microscope.
A simple microscope.
A hand lens.
A graduated cylinder.

Correct Answer

A. A compound microscope.

Explanation

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.

Which of these are living things?

plastic wrap, kitchen sponge, star
Sun, static electricity, cotton
Sunflower, ladybug, sea sponge
Water, coral, seaweed

Correct Answer

A. Sunflower, ladybug, sea sponge

Explanation

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.

A living thing made of more than one cell is called

Single celled.
Multi-cellular.
Convex celled.
compound celled.

Correct Answer

A. Multi-cellular.

Explanation

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.

A brown mouse and a white mouse mate. What might their children look like?

All four are brown.
Three are brown and one is white.
Both A and B are possible.
None of the above.

Correct Answer

A. Both A and B are possible.

Explanation

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.
