    What is stimulus?

    • A bone in your elbow

    • A muscle in your leg

    • A reaction/ response

    • Kind of study among scientists

    Correct Answer
    A. A reaction/ response
    Explanation
    Stimulus refers to a reaction or response that occurs as a result of a certain action or event. It is not related to any specific body part like a bone in your elbow or a muscle in your leg. Additionally, stimulus is not a kind of study among scientists, but rather a concept that is studied and observed in various scientific fields.

    How can you tell something is living?

    • It's moving

    • It has organs and DNA(cells, bones)

    • It is 2 different colors

    • It produces food

    Correct Answer
    A. It has organs and DNA(cells, bones)
    Explanation
    The presence of organs and DNA (cells, bones) is a key characteristic of living organisms. Organs are specialized structures that perform specific functions within an organism, while DNA carries the genetic information that determines the traits and characteristics of an organism. Both organs and DNA are essential components of living organisms and are not present in non-living things. Therefore, the presence of organs and DNA is a reliable indicator that something is living.

    If you lose an electron you gain a positive charge.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When an atom loses an electron, it becomes positively charged because there are now more protons (positively charged particles) than electrons (negatively charged particles) in the atom. This imbalance of charges creates a net positive charge. Therefore, losing an electron results in gaining a positive charge.

    Rate this question:

  • 5. 

    If you gain an electron you gain a positive charge

    • True

    • False

    Correct Answer
    A. False
    Explanation
    When an atom gains an electron, it actually gains a negative charge, not a positive charge. Electrons are negatively charged particles, so when an atom gains an electron, the overall charge of the atom becomes more negative. Therefore, the statement that gaining an electron results in a positive charge is incorrect.

    A buffer is which of the following:

    • Acid

    • Base

    • Weak acid or base that can react with strong acids or bases to help prevent sharp sudden changes in PH

    • Really strong acid or bast the will make sharp sudden changes in PH levels

    Correct Answer
    A. Weak acid or base that can react with strong acids or bases to help prevent sharp sudden changes in pH
    Explanation
    A buffer is a weak acid or base that can react with strong acids or bases to help prevent sharp sudden changes in pH. Buffers are able to maintain a relatively stable pH by absorbing or releasing hydrogen ions (H+) in response to changes in the environment. This ability to resist changes in pH is important for maintaining the proper functioning of biological systems, as many biochemical reactions are sensitive to pH levels.

  • 7. 

    If two animals mated that were a different species, they have an offspring, that offspring can make a baby with another animal and have a offspring just like its self.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because when two animals of different species mate, they usually produce infertile offspring, meaning the offspring cannot reproduce. This is because different species have different numbers of chromosomes and genetic makeup, which prevents successful reproduction. Even if the hybrid offspring is fertile, it is unlikely to find a mate of the same species to reproduce with, resulting in the end of the genetic line.

    What is an ionic bond?

    • When one atom donates an electron to another atom of a different element.

    • When one atom keeps all of its electrons

    • When two atoms combine and make a super atom

    • When three atoms combine

    Correct Answer
    A. When one atom donates an electron to another atom of a different element.
    Explanation
    An ionic bond is formed when one atom donates an electron to another atom of a different element. This transfer of electrons creates charged particles called ions, with one atom becoming positively charged (cation) and the other atom becoming negatively charged (anion). The opposite charges attract each other, resulting in the formation of a strong bond between the two atoms. This type of bond typically occurs between metals and non-metals, where the metal atom donates an electron to the non-metal atom.

  • 9. 

    What is a covalent bond?

    • When an atom keeps all the electrons

    • When an atom only shares some of its electrons(hogs some)

    • When an atom cant escape an electron cloud

    • When the valence electrons are all gone this occurs

    Correct Answer
    A. When an atom only shares some of its electrons(hogs some)
    Explanation
    A covalent bond is formed when two atoms share a pair of electrons. In this type of bond, neither atom completely loses or gains electrons, but instead, they share them. The correct answer, "When an atom only shares some of its electrons (hogs some)," accurately describes the concept of a covalent bond, where the atoms involved share electrons but do not keep or lose all of them.

    Acid  is a compound that forms from hydrogen ions in solutions

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because acids are compounds that release hydrogen ions (H+) when dissolved in water. These hydrogen ions then interact with water molecules to form hydronium ions (H3O+). Therefore, acids are characterized by their ability to donate protons (H+) in a solution.

    What is asexual reproduction?

    • Meosis; It reproduces on its own

    • Mitosis; It reproduces on its own

    • Meosis; Two contribute

    • Mitosis; Two contribute

    Correct Answer
    A. Mitosis; It reproduces on its own
    Explanation
    Mitosis is the correct answer because asexual reproduction involves the production of offspring that are genetically identical to the parent. In mitosis, a single cell divides into two identical daughter cells, each with the same genetic material as the parent cell. This process allows an organism to reproduce on its own without the need for a mate or the contribution of genetic material from another individual. Meiosis, on the other hand, involves the division of cells that results in the production of gametes with half the genetic material of the parent cell, and it requires the contribution of genetic material from two individuals.

     What is an isotope?

    • Atoms with equal protons, nuetrons, and electrons.

    • Atoms of the same element that differ in the # of nuetrons

    • Atoms that have no nucleus

    • Atoms with no valence electrons

    Correct Answer
    A. Atoms of the same element that differ in the # of nuetrons
    Explanation
    An isotope refers to atoms of the same element that have the same number of protons but differ in the number of neutrons. Isotopes have the same atomic number but different atomic mass. This difference in the number of neutrons can result in variations in stability and other physical properties of the atom.

    What is a hydrogen bond?

    • When hydrogen attracts only oxygen

    • When Hydrogen only attracts nitrogen

    • When hydrogen has the possibility to attract oxygen, nitrogen, and floride

    • When hydrogen doesnt attract anything

    Correct Answer
    A. When hydrogen has the possibility to attract oxygen, nitrogen, and floride
    Explanation
    A hydrogen bond is a type of attractive force that occurs when a hydrogen atom is bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine. In this bond, the hydrogen atom has a partial positive charge, while the electronegative atom has a partial negative charge. This creates a strong electrostatic attraction between the two atoms, resulting in a hydrogen bond. Therefore, the correct answer is "When hydrogen has the possibility to attract oxygen, nitrogen, and fluoride."

    A ph scale is something that measures the concentration of hydrogen ions in solutions.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because a pH scale is indeed used to measure the concentration of hydrogen ions in solutions. The pH scale ranges from 0 to 14, with 7 being neutral. Solutions with a pH less than 7 are considered acidic, while solutions with a pH greater than 7 are considered basic or alkaline. The concentration of hydrogen ions in a solution determines its acidity or alkalinity, and the pH scale provides a quantitative measure of this concentration.

    When an reaction occurs and makes ions all the atoms involved become charged. And this only occurs between metals and non-metals.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When a reaction occurs and forms ions, the atoms involved become charged. This is due to the transfer of electrons between the atoms. This process typically occurs between metals and non-metals, as metals tend to lose electrons and non-metals tend to gain electrons. Therefore, the statement is true.

    Rate this question:

  • 16. 

    Atomic #- Is the number of protons. Atomic Mass- # of protons and nuetrons

    Correct Answer
    Protons
    Protons; nuetrons
    Explanation
    The atomic number refers to the number of protons in an atom, while the atomic mass refers to the sum of protons and neutrons. Therefore, the correct answer is "Protons, Protons; neutrons" because it accurately describes the components that contribute to both the atomic number and atomic mass.

    The process by which cells maintain a stable internal environment, despite changes in external conditions, is known as ____________, and it involves complex feedback mechanisms that regulate factors such as temperature, pH, and glucose levels.

    Correct Answer
    homeostasis, Homeostatis
    Explanation
    Homeostasis is the process by which cells and organisms maintain a stable internal environment, crucial for survival. It involves complex feedback mechanisms that regulate variables such as temperature, pH, and glucose levels. These mechanisms ensure that, despite external changes, the internal conditions remain within a narrow, optimal range. Disruptions in homeostasis can lead to disease or dysfunction, making it a fundamental concept in biology and physiology.

    A non- polar bond is when _______________________________________.Which is most likely correct?

    • Elements share equally in atoms

    • Elements dont share atoms

    • Elements share 5 atoms

    • Elements share 1000 atoms

    Correct Answer
    A. Elements share equally in atoms
    Explanation
    A non-polar bond is when elements share equally in atoms. This means that the electrons in the bond are shared equally between the atoms, resulting in a balanced distribution of charge. In a non-polar bond, there is no significant difference in electronegativity between the atoms involved, leading to an equal sharing of electrons.

    Rate this question:

  • 19. 

    A Base is something that does not produce hydroxide ions in a solution

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A base is a substance that produces hydroxide ions in a solution. This is because bases are typically compounds that can accept protons (H+) from an acid, causing the release of hydroxide ions (OH-) in the process. Therefore, the statement that a base does not produce hydroxide ions in a solution is incorrect.

    Rate this question:

  • 20. 

    A mixture is when two or more compounds chemically combine.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. A mixture is when two or more compounds are physically combined, not chemically combined. In a mixture, the compounds retain their individual properties and can be separated through physical means, such as filtration or evaporation. Chemical combination, on the other hand, involves a reaction where the compounds lose their individual properties and form new substances.
