What process add carbon dioxide to the atmosphere
-
Burning, decay and respiration
-
Burning, decay and photosynthesis
-
Respiration, decay and photosynthesis
-
Burning, photosynthesis and respiration
Correct Answer
A. Burning, decay and respirationExplanation
Burning, decay, and respiration are all processes that add carbon dioxide to the atmosphere. Burning releases carbon dioxide when organic materials such as fossil fuels, wood, or plants are combusted. Decay of organic matter also produces carbon dioxide as organic materials break down. Respiration, both by humans and animals, involves the exchange of gases, including the release of carbon dioxide into the atmosphere. Therefore, all three processes contribute to the increase of carbon dioxide in the atmosphere.Rate this question:

Organisms involved in decay are called decomposers. What role do decomposers play in the carbon cycle?
-
Provide food for animals
-
Allow carbon to be reused
-
Limit the number of plants in an ecosystem
-
Remove carbon dioxide from the atmosphere
Correct Answer
A. Allow carbon to be reusedExplanation
Decomposers play a crucial role in the carbon cycle by allowing carbon to be reused. When decomposers break down dead organisms and waste materials, they release carbon back into the environment. This carbon can then be used by other organisms for growth and energy. Without decomposers, carbon would remain locked in dead organic matter and unavailable for reuse, disrupting the carbon cycle and limiting the availability of this essential element for other organisms.Rate this question:

Which process has a role in the growth and repair of tissue in multicellular organisms?
-
Coordination
-
Cell division
-
Mutation
-
Sexual reproduction
Correct Answer
A. Cell divisionExplanation
Cell division is the correct answer because it is the process responsible for the growth and repair of tissues in multicellular organisms. During cell division, a single cell divides into two daughter cells, each with the same genetic material as the parent cell. This allows for the growth of tissues by increasing the number of cells, as well as the repair of damaged or injured tissues by replacing damaged cells with new ones. Coordination, mutation, and sexual reproduction do not directly play a role in the growth and repair of tissues.Rate this question:

-
Atoms are rearranged
Correct Answer
A. Atoms are rearrangedExplanation
When a new compound is formed, the atoms involved in the reaction undergo rearrangement. This means that the atoms are reorganized and bonded together in a different arrangement than before. No atoms are lost or destroyed, and new matter is not created. Instead, the existing atoms are rearranged to form the new compound with different chemical properties.Rate this question:

The human stomach contains acid. Sodium bicarbonate (NaHCO3) is often found as a component of antacids, which are used to settle upset stomachs. It reacts in a similar way to normal carbonates, causing people to burp. Why does sodium bicarbonate make people burp?
-
It produces hydrogen gas.
-
It solidifies in the stomach.
-
It produces carbon dioxide gas.
-
It settles on top of the stomach contents.
Correct Answer
A. It produces carbon dioxide gas.Explanation
Sodium bicarbonate reacts with the acid in the stomach to produce carbon dioxide gas. This gas builds up and creates pressure in the stomach, leading to burping as a way for the body to release the excess gas.Rate this question:

Correct Answer
A. Non-InfectiousExplanation
Melanoma is a type of cancer that develops in the melanocytes, which are the cells that produce melanin. It is not caused by an infection or a contagious agent. Instead, melanoma is primarily caused by exposure to ultraviolet (UV) radiation from the sun or tanning beds, as well as genetic factors. Therefore, it is classified as a non-infectious disease.Rate this question:

Our sun is a medium size star. As it gets older, it will use up its fuel. What is most likely to happen during the next stage of its life?
-
Contract
-
Expand
-
Explode
-
No change
Correct Answer
A. ExpandExplanation
As the sun gets older and uses up its fuel, it will enter the next stage of its life, which is expansion. This is because as the fuel in the sun's core depletes, the balance between the outward pressure from nuclear fusion and the inward pull of gravity becomes disrupted. The outer layers of the sun will then expand, causing it to become a red giant. Eventually, the sun will shed its outer layers and form a planetary nebula, leaving behind a dense core known as a white dwarf.Rate this question:

Cobalt-60 is commonly used for cancer treatment therapies. How many neutrons are there in an atom of 6027 Co ?
-
27
-
33
-
60
-
87
Correct Answer
A. 33Explanation
Cobalt-60 is an isotope of cobalt that is commonly used in cancer treatment therapies because it emits gamma radiation. The number after the element symbol in the question, 6027Co, represents the atomic mass of cobalt-60. The atomic mass is the sum of the number of protons and neutrons in the nucleus of an atom. Since the atomic mass is 60, and the atomic number (number of protons) for cobalt is 27, we can subtract the atomic number from the atomic mass to find the number of neutrons. Therefore, there are 33 neutrons in an atom of 6027Co.Rate this question:

-
By increasing atomic number and similar properties.
-
By increasing atomic weight and similar properties.
-
Alphabetically by name.
-
By number of electrons.
Correct Answer
A. By increasing atomic weight and similar properties.Explanation
Dmitri Ivanovich Mendeleev arranged the elements in the periodic table by increasing atomic weight and similar properties. This means that he organized the elements based on their atomic weights, with the lighter elements coming first and the heavier elements coming later. Additionally, he grouped elements with similar properties together, creating a pattern in the periodic table that allowed for the prediction of undiscovered elements and their properties.Rate this question:

Which is considered the greatest triumph of Mendeleev's periodic table, which earned him the distinction as the "Father of the Modern Periodic Table"?
-
The use of rows and columns to organize the elements
-
The ability to predict electron configurations of elements
-
The use of atomic numbers as an organizing criterion
-
The prediction of the existence of undiscovered elements.
Correct Answer
A. The prediction of the existence of undiscovered elements.Explanation
Mendeleev's greatest triumph in the development of the periodic table was his ability to predict the existence of undiscovered elements. By arranging the known elements based on their properties and patterns, Mendeleev was able to identify gaps in the table where elements were missing. He predicted the properties of these missing elements and even left spaces for them in his table. Later, when these elements were discovered and their properties matched Mendeleev's predictions, it provided strong evidence for the accuracy and usefulness of his periodic table. This achievement solidified Mendeleev's reputation as the "Father of the Modern Periodic Table."Rate this question:
