Trivia Questions On Easy Science

An organ is a group of tissues that work together to perform a specific function in the body. This definition accurately describes an organ, as it is composed of different tissues that collaborate to carry out a particular task. Reptile, marine biologist, and thermometer do not fit this definition and are unrelated to the concept of tissues working together.

A round, shallow dish that is commonly used in laboratories is known as a Petri dish. It is used to culture microorganisms or small plants for scientific research and experimentation. This definition perfectly aligns with the term "Petri dish", making it the correct answer.

A log jam is a term used in science to describe wooden logs or other tree debris that obstruct the flow of water in a channel. This obstruction can cause a buildup of water and lead to flooding or other water-related issues. Log jams can occur naturally or be caused by human activities such as deforestation. They can have significant impacts on ecosystems and water flow dynamics.

Nearsightedness, also known as myopia, is a condition in which a person can see nearby objects clearly, but objects in the distance appear blurry. This occurs because the eyeball is longer than normal or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. As a result, the images of distant objects are not properly formed on the retina, leading to blurred vision. This definition accurately describes the term "nearsightedness."

The definition provided perfectly describes nectar, which is a sweetish liquid found in many flowers and is used by bees to make honey. Nectar is a common term in the field of botany and entomology, specifically in the study of pollination and bee behavior. It is an essential resource for bees and plays a crucial role in the process of honey production.

Pasteurization is the best fit for the given science term because it involves the process of preserving food by heating it to a specific temperature to kill harmful bacteria and extend its shelf life. This method was developed by Louis Pasteur in the 19th century and is commonly used in the food industry to ensure food safety.

Germination is the process where a seed, spore, or zygote begins to sprout. This term specifically refers to the initial stage of growth in plants, where the seed absorbs water, swells, and eventually develops into a new plant. It is a crucial process in plant reproduction and is influenced by factors such as temperature, moisture, and light. Solar flare, footcandle, and elliptical orbit do not pertain to the process of seed or spore growth, making germination the correct answer.

Hard water is the correct answer because it is defined as water that contains minerals like calcium carbonate, magnesium carbonate, and bicarbonate. These minerals can cause issues such as scale buildup in pipes and appliances, and can also affect the lathering ability of soaps and detergents.

An action pertaining to the movement of liquids, especially water, is best described as hydraulic. Hydraulic refers to the study or use of fluid mechanics in order to generate, control, or transmit power through the use of pressurized liquids, such as water. This term is commonly used in various fields, including engineering and machinery, where hydraulic systems are used to transfer force or motion.

Incubation refers to the process of maintaining a constant temperature and humidity in order to allow an embryo to develop. This term is commonly used in biology and refers to the controlled conditions necessary for the growth and development of living organisms, particularly embryos. The other options, such as dew point, magnum, and carcinogen, do not relate to the specific process of maintaining constant temperature and humidity for embryo development.

The definition of "a sensation of suffering due to some form of stimulation of nerve endings" best fits the science term "Pain". Pain is a subjective experience that is typically associated with physical injury or illness. It is caused by the activation of nerve endings called nociceptors, which transmit signals to the brain, resulting in the perception of pain. This definition accurately describes the concept of pain, making it the correct answer in this context.

Lactose intolerance refers to the inability to digest lactose, which is the predominant sugar found in milk. People with lactose intolerance lack the enzyme lactase, which is needed to break down lactose into simpler forms that can be absorbed by the body. As a result, consuming milk or dairy products can cause symptoms such as bloating, diarrhea, and stomach cramps. Therefore, "The inability to digest the predominant sugar of milk" best fits the science term of lactose intolerance.

A lake is a water-filled basin that can have limited or no outlet. It is a body of water surrounded by land and can be formed by various geological processes such as tectonic activity, glaciation, or volcanic activity. Lakes can vary in size, depth, and water sources. They can be freshwater or saline and are important ecosystems supporting diverse plant and animal life. The given definition accurately describes a lake, making it the correct answer.

Gene mapping is the most appropriate science term for the definition provided. Gene mapping refers to the process of determining the relative positions of genes on a DNA molecule. It involves identifying the location and order of genes on a chromosome, which helps in understanding their functions and how they contribute to various traits and diseases. This process is crucial in genetic research and plays a significant role in fields like medicine, agriculture, and evolutionary biology. Therefore, gene mapping is the correct answer that aligns with the given definition.

A placebo is a substance or treatment that has no therapeutic effect on the test subject. It is often used in medical research to compare the effectiveness of a new treatment against a control group. The definition provided perfectly describes a placebo, as it is a substance that does not produce any effects on the test subject.
