Answer the following question given this paragraph: 4.2 Newton's First Law of Motion: Inertia Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object's mass. Mass is the quantity of matter in a substance. Q: What is the tendency of an object to remain at rest or remain in motion called? Choices: - impetus - magnetism - flow - inertia A:
inertia

Answer the following question given this paragraph: It could easily be said that a cell is the fundamental unit of life, the smallest unit capable of life or the structural and functional unit necessary for life. But whatever it is, a cell is necessary for life. This concept will discuss some of the fundamental properties of the cell with lessons that include the cell structure, transport in and out of the cell and cell communication. Q: What is considered to be the "fundamental unit" of life? Choices: - proton - organ - bacteria - cell A:
(Answer)
cell
Ques: Answer the following question given this paragraph: The most important source of electromagnetic waves on Earth is the sun. Electromagnetic waves travel from the sun to Earth across space and provide virtually all the energy that supports life on our planet. Many other sources of electromagnetic waves depend on technology. Radio waves, microwaves, and X rays are examples. We use these electromagnetic waves for communications, cooking, medicine, and many other purposes. Q: What is the most important source of electromagnetic waves on earth? Choices: - cell phones - wireless networks - radios - the sun A:
Ans: the sun

Answer the following question given this paragraph: Plastids are membrane-bound organelles with their own DNA. Examples are chloroplasts and chromoplasts. Chloroplasts contain the green pigment chlorophyll and carry out photosynthesis . Chromoplasts make and store other pigments. They give flower petals their bright colors. Q: What are membrane-bound organelles with their own dna called? Choices: - vacuoles - chromosomes - ribosomes - plastids A:
(A).
plastids

Ans:stamen
Ques:Answer the following question given this paragraph: Summary Nuclear reactions are accompanied by large changes in energy, which result in detectable changes in mass. The change in mass is related to the change in energy according to Einstein's equation: E = (m)c2. Large changes in energy are usually reported in kiloelectronvolts or megaelectronvolts (thousands or millions of electronvolts). With the exception of 1H, the experimentally determined mass of an atom is always less than the sum of the masses of the component particles (protons, neutrons, and electrons) by an amount called the mass defect of the nucleus. The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles. In nuclear fission, nuclei split into lighter nuclei with an accompanying release of multiple neutrons and large amounts of energy. Thecritical mass is the minimum mass required to support a self-sustainingnuclear chain reaction. Nuclear fusion is a process in which two light nuclei combine to produce a heavier nucleus plus a great deal of energy. Q: In which process do two light nuclei combine to produce a heavier nucleus and great energy? Choices: - general fusion - light fusion - certain fusion - nuclear fusion A:

Ans:
nuclear fusion
