13. The Law of Conservation of Mass states that matter cannot be created or destroyed but transferred. This law was proven by the scientist Antoine Lavoisier, who heated various substances and documented quantitative relationships. His observations proved that the mass of the reactants is equal to the mass of the product in a chemical reaction. Justify (give good reason) why Lavoisier's conclusions were considered a law instead of a theory, A. Lavoisier attempted to explain the results of his experiments. B. Lavoisier provided sufficient empirical evidence to support his claim.. Lavoisier provided an explanation of an observed phenomena in nature. D. Lavoisier applied the results of one experiment to explain a wide variety of circumstances.
The most observed human variations changes gradually rather than having discrete boundaries as expected-This gradual change is referred to as a? Cine Slow change Gradient Clinal Please and thank you
What is determined by genes that direct the amount of eumelanin or pheomelanin produced by melanocytes associated with hair follicles?
Rats are endothermic (warm blooded) animals. Explain why the physiology of a perch (an exothermic or cold blooded animal) would not support the metabolic needs of a rat.
Explain how the reproductive system of each animal corresponds to the environment that they live in and compare it to the energy needed for reproduction. 1. Earthworm 2. Crayfish 3. Squid 4. Perch 5. Rat
describe another situation in which the cell cycle short to allow rapid cell division before returning to normal
Using pictures and text, compare and contrast the digestive, circulatory and respiratory systems of an earthworm, crayfish, squid, perch and rat.
1. Imagine that your biology class is going to dissect a rabbit. Using your understanding of phylogeny and the knowledge used from previous dissections, predict and explain what a rabbit’s respiratory, digestive and reproductive systems will look like. Fully explain, using pictures and the terms and information learned in lecture and lab. Be sure to include which animal you are comparing the rabbit to and why you are comparing it to that animal(compare to a rat). Do not just name organs.
How does the body respond if the skeletal system does not function properly? I would like a detailed answer please :)
