In QRS, mQ = 70, mR = 44, and mS = 66. Which side of QRS is the shortest?a. Cannot be determined b. RS c. QR d. QS
Answers
Answer 1
Answer:
The answer will be d. QS With the given set of angles, we can conclude that this is a scalene triangle provided that the measurement of the angles given are different. Logically, if you will try to infer to the given angles, you can conclude that the bigger the angle, the wider the opposite side will be and the smaller the angle, the shorter the opposite side will be. In the Given angles, R has the smallest angle of 44, meaning it will also have the shortest opposite side and that will be QS.
P450 encodes an enzyme that detoxifies insecticides. Abc8 encodes a transporter protein thatpumps insecticides out of cells. Cps encodes an external structural protein located in theexoskeleton that greatly reduces the absorption of insecticides. Based on this information andthe data in Figure 1, explain how a deletion of both P450 and Abc8 results in lower survival inbedbugs compared with a deletion of Cps only.

15. Which of the following is not an accurate description of chemical reactions? A. The rates of chemical reactions can vary. B. Chemical reactions that take in energy never need a source of energy to start. C. During chemical reactions, energy can be released or used up. D. During chemical reactions, bonds can be broken or formed.
Answers
The correct answer is "B". All chemical reactions require "activation energy". Activation energy can be thought of as kickstarting a chemical reaction. If you consider lighting a match, the match does not spontaneously combust upon its removal from the matchbox. You must kickstart the reaction by heating the chemicals in the match head. This heat is generated by the friction of rubbing the match head against the side of the box.In any case, reactions that take in energy, must take that energy from somewhere, so they absolutely need a source of energy to start, and to continue!

Which describes the relationship between a genotype, a phenotype, and an organism’s experiences?
Answers
the one that describes the relationship between a genotype, a phenotype, and an organism’s experiences would be:A genotype is an organism's allele combination. A phenotype is the physical appearance of a trait in an organism, which may be influenced by the organism’s experiences.A genotype exist since birth and couldn;t be influenced by anything else, meanwhile a phenotype that an organism have will be influenced by a lot of external factors
We are asked to describe the relationship between a genotype, a phenotype, and an organism's experiences. The answer is that the genotype pertains to an organism's allele combination while a phenotype is the physical features which may be influenced by an organism's experience.

Animal cells have all of the following exceptA. mitochondria. B. chloroplasts. C. a nucleus. D. Golgi apparatus.
Answers
Animal cells do not have chloroplasts, so answer choice (B) is the correct one. All animals (unless there are any bizarre exceptions that I'm not aware of, or as long as we're not categorizing some unicellular organisms as animals) are eukaryotic, which means that their cells contain nuclei, meaning that (C) is not valid. Mitochondria are found in all eukaryotic cells, including those of mammals, so (A) is also not correct. The Golgi apparatus is another organelle found in eukaryotic cells, and they are found in animal cells, so (D) is not correct. But chloroplasts are the organelles responsible for conducting photosynthesis, which is something that only plants and not animals are capable of, so there are no chloroplasts in animal cells.
