Science Roots Test -- Part 1

Explanation
The root "hydro(a)" is derived from the Greek word "hydor," which means water. Therefore, in the given options, the correct answer is "water." The words "hydrogen," "hydrate," and "hydrology" all relate to water in some way. Hydrogen is a gas that combines with oxygen to form water, hydrate refers to a compound that contains water molecules, and hydrology is the study of water and its distribution on Earth.

Explanation
The root "chlor" in chlorophyll, chloroplast, and chlorin refers to the color green. Chlorophyll is the pigment found in plants that gives them their green color and is essential for photosynthesis. Chloroplasts are the organelles in plant cells where photosynthesis takes place. Chlorine is a chemical element that is also associated with a greenish-yellow color. Therefore, the correct answer is green.

Explanation
The root "vor" in the given words voracious, carnivore, and herbivore refers to the action of eating. These words are related to the consumption of food. "Voracious" means having a very eager approach to eating or consuming a large amount of food. "Carnivore" refers to an animal that primarily eats meat, while "herbivore" refers to an animal that primarily eats plants. Therefore, the correct answer is "eat".

Explanation
The correct answer is "environment". The root "eco" in words like ecosystem, ecology, and ecotype refers to the natural surroundings or habitat in which organisms live. It encompasses the physical, chemical, and biological factors that interact to create a particular environment.

Explanation
The correct answer is "star". The root "astro" is derived from the Greek word "astron" which means "star". This root is commonly used in words related to celestial bodies and the study of space. Therefore, "star" is the most appropriate choice as it directly relates to the root "astro" and its meaning.

Explanation
The root "bio" in biology, biosphere, and biologist refers to "life". This is evident from the fact that all of these words are related to the study or existence of living organisms. "Biology" is the scientific study of life, "biosphere" refers to the regions of the Earth where life exists, and a "biologist" is a scientist who studies living organisms. Therefore, the correct answer is "life".

Explanation
The root "hypo" in the words hypothermia, hypodermic, and hypotension indicates a meaning of "low/under/below." This can be understood by looking at the definitions of these words. Hypothermia refers to a condition of abnormally low body temperature, hypodermic refers to something that is administered under the skin, and hypotension refers to low blood pressure. Therefore, the correct answer is "low/under/below."

Explanation
The root "photo/phos" in words like photosynthesis, photoelectric, and photography means light. This is evident from the fact that all these words are related to the concept of light. Photosynthesis is the process by which plants convert light energy into chemical energy, photoelectric refers to the emission of electrons when light is shone on certain materials, and photography is the art or practice of capturing and developing images using light. Therefore, the correct answer is light.

Explanation
The correct answer is "hydr" because firefighters use a fire hydrant to access water and extinguish fires. A fire hydrant is a device connected to a water supply that provides firefighters with a ready source of water to combat fires.

Explanation
The correct answer is "astro" because Gemini is an astrological sign. "Astro" is a prefix that relates to celestial bodies and their influence on human behavior and personality traits. Therefore, it is logical to say that an astrological sign is a Gemini.

Explanation
The chemical is a biohazard because it poses a threat to living organisms or the environment.

Explanation
The correct answer is "vor". The word "vor" is a suffix that means "having a strong desire for" or "having a large appetite for". Therefore, the phrase "voracious appetite" means having a very large or insatiable appetite.

Explanation
If you are "photosensitive," that means you are sensitive to light. The prefix "photo-" refers to light, so "photo" is the correct answer.

Explanation
Chlorophyll reflects on green light because it contains pigments that absorb light energy from the sun for photosynthesis. These pigments primarily absorb red and blue light, while green light is reflected, giving chlorophyll its characteristic green color. This allows plants to utilize the absorbed light energy to convert carbon dioxide and water into glucose and oxygen, which is essential for their growth and survival.

Explanation
The correct answer is "eco" because ecology is the study of organisms and their environment. Ecology focuses on the relationships between living organisms and their surroundings, including interactions with other organisms, the physical environment, and the flow of energy and nutrients.

Explanation
The correct answer is "hypo." The term "hypo" is a prefix that means "below" or "under." In the context of the question, "hypo" refers to the deepest layer of the skin, which is called the hypodermis. The hypodermis is located beneath the dermis and is composed of fatty tissue and connective tissue. It serves as insulation, cushioning, and energy storage for the body.
