The answer is C because the key is “group that live in the same area”
Answer:
The correct selection of answers to the question: Identify the pieces of evidence describing the features of DNA that Watson and Crick used to determine the structure of DNA, would be:
C: The two chains are parallel, both running in a 5´ to 3´ direction
D: A purine base forms hydrogen bonds to pair with a pyrimidine base located on the opposite DNA strand. Specifically, A pairs with T, and C pairs with G.
E: The sugar-phosphate backbones of each DNA helix run antiparallel to one another
F: The diameter of the DNA doube helix is 2 nm, with each purine-pyrimidine base pair spanning an equivalent distance between the two chains.
Explanation:
Although Watson´s and Crick´s research, and model of the DNA helix, became the breakthrough for science, as it visually presented the now known characteristics of DNA, this research was possible due to the way that these two researchers used previous information found by other scientist on the molecule, to finally build their model. All of the options that were selected were part of the research of several scientis, including Mendel, Rosalin Franklin, Linus Pauling, Maurice Wilkins, Oswald Avery and many others, who worked on different aspects of specimens and their specific characteristics, and which led them to discover that organisms possessed DNA, that this was the unit of information that directed all functions in living cells and how this DNA helix was chemically built to understand how it worked, and why it worked the way it did.
Answer:
A: Large fins
Explanation:
Large fins help it propell through the ocean fast.
Answer:
The Testes.
Explanation:
Testes are contained in a sac of skin called the scrotum, it produces sperm, then make hormone testosterone. It aids testosterone which promotes the development of secondary sexual characteristics, which in humans include a deeper voice, more body hair, and more powerful muscles than that in their counterparts which are the female.
Answer:
The correct answer would be option D, Can help make sense of difficult problems.
Explanation:
In simple words, simulation is the Model. Simulation is the imitation of some procedure or method or process or situation. We can say it deception as well. Simulation is used as a method of analysis. When there are complex situations or processes that need to be tested before launching into the general public or to be used in the scientific researches or anything, Simulation is used. Simulation imitates the situation, checks for any errors, experiments the inputs and see the outputs of the process, method, system, etc, which they have developed. So A scientist uses simulation because it can help make sense of difficult problems.
