a) maggots appearing on rotten meat
2) which piece of empirical evidence is qualitative data?
a) The soup taste salty.
3) how did new evidence found by Marie Tharp and Bruce Heezen add onto Continental drift and create the theory of plate tectonics?
a) they showed what the oceans floors looked like helped explain how continents move over time.
4) which word best describes the statement that mass is neither maid nor destroyed by chemical reactions or physical changes?
a) law
5) which part of newtons second law of motion explains why it is easier to push an empty cart than full one?
a) A greater force is needed to move an object with a greater mass.
well I guess but
A greater force is needed to ACCELERATE an object with a greater mass.
1) The answer is a) maggots appearing on rotten meat. To understand why this supported the theory of spontaneous generation, we need to explain what the theory is. Spontaneous generation is the idea that living organisms can arise from non-living matter. For centuries, it was believed that things like maggots could spontaneously generate from rotting meat. This belief was based on observation and anecdotal evidence - people observed that maggots appeared on meat that was left out, seemingly appearing out of nowhere. This was seen as evidence supporting the idea that life could spontaneously generate.
However, it was later discovered through experiments by scientists like Louis Pasteur that the maggots were actually the result of flies laying eggs on the meat, not spontaneously generated. This disproved the theory of spontaneous generation and provided evidence for the concept of biogenesis, which states that life can only come from pre-existing life.
2) The answer is a) The soup tastes salty. Qualitative data refers to observations that describe qualities or characteristics, typically using words instead of numbers. In this case, the observation is about the taste of the soup, which is a subjective description using the word "salty" rather than a quantitative measurement.
3) The answer is a) They showed what the ocean floors looked like and helped explain how continents move over time. Marie Tharp and Bruce Heezen were geologists who conducted extensive research on the ocean floors. They created detailed maps and profiles of the ocean floors, revealing the presence of mid-ocean ridges, trenches, and other features. This new evidence provided crucial support for the theory of continental drift proposed by Alfred Wegener.
Wegener had suggested that the continents were once connected in a supercontinent called Pangaea and that they had drifted apart over time. However, without a clear understanding of what lay beneath the oceans, Wegener's theory faced skepticism. Tharp and Heezen's maps helped demonstrate the patterns of seafloor spreading and the movement of tectonic plates. This ultimately led to the development of the theory of plate tectonics, which explains how the Earth's crust is divided into plates that move and interact with each other.
4) The word that best describes the statement that mass is neither made nor destroyed by chemical reactions or physical changes is "law." This statement refers to the law of conservation of mass or the principle of mass conservation, which states that in any closed system, the total mass remains constant over time. This fundamental law in chemistry and physics means that during chemical reactions or physical changes, the total mass of the reactants will always equal the total mass of the products.
5) The answer is a) A greater force is needed to move an object with a greater mass. Newton's second law of motion, often expressed as F=ma (force = mass x acceleration), explains how the motion of an object is related to the force applied to it. According to this law, the force required to move an object is directly proportional to its mass. In simpler terms, it means that the more massive an object is, the more force is needed to accelerate it or move it. In the context of the question, it is easier to push an empty cart compared to a full one because the empty cart has less mass and therefore requires less force to move.
1) The maggots appearing on rotten meat supported the theory of spontaneous generation.
2) The statement "The soup tastes salty" is qualitative data as it describes a sensory perception.
3) Marie Tharp and Bruce Heezen's new evidence, which showed what the ocean floors looked like, helped explain how continents move over time and contributed to the theory of plate tectonics.
4) The word "law" best describes the statement that mass is neither made nor destroyed by chemical reactions or physical changes. This statement refers to the law of conservation of mass.
5) The part of Newton's second law of motion that explains why it is easier to push an empty cart than a full one is "A greater force is needed to move an object with a greater mass." According to Newton's second law, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. So, a greater force is needed to accelerate an object with a greater mass.
