PUBLIC Questiоn 1: Anаlyzing Cоncepts аnd Predicting Outcоmes – Biology Give аn in-depth explanation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. Two thousand years in the future, astronauts from Earth have landed on a planet in a neighboring solar system to investigate recently detected signs of life. The atmosphere on Planet 89 is very similar to Earth - 73% nitrogen, 22% oxygen, and less than 5% carbon dioxide. The astronaut’s ship landed on the edge of a shallow body of water. The water contains much higher levels of iodine and nitrates than would usually be present in water from Earth. 1B. Predict what would happen if the astronauts bring these samples back to Earth. Assume you confirm that these organisms are alive. Will they survive on Earth? Explain your prediction. (2 pts) Copyright 2022 by Edmonds College Department of Biology. All rights reserved.

PUBLIC Questiоn 2: Cоmpаre аnd Cоntrаst – Macromolecules Give an in-depth explanation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. Several macromolecules are necessary for life as we know it (proteins, nucleic acids, carbohydrates and lipids). It is important to not only understand the basic elemental composition of these macromolecules but also the complex three dimensional structures they adopt to carry out their functions. 2B. Relate the STRUCTURE of a carbohydrate to the specific FUNCTION of this macromolecule in a cell. Your discussion should include the specific monomers that are brought together to form the polymer and what chemical reaction, if any, is needed to make the primary structure of this macromolecule. Also describe the secondary and tertiary structures these macromolecules can form, including their relevant molecular interactions. Include at least TWO specific examples of carbohydrates relevant to your discussion. (5 pts) Copyright 2022 by Edmonds College Department of Biology. All rights reserved.

PUBLIC Questiоn 3: Anаlyzing Cоncepts & Predicting Outcоmes- Nucleic Acid Forms & Functions Give аn in-depth explаnation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. Nucleic acids are broadly categorized by the sugar that forms the phosphodiester backbone - either ribose or deoxyribose. There are also important differences in the nitrogenous bases for these nucleic acids, and the types of secondary structures they form. Importantly, one type of nucleic acid exists within the cell primarily as single strands while the other type exists primarily as double strands. However, both types of nucleic acids are able to bind to complementary sequences, forming hydrogen bonds between nitrogenous bases. Consider the following sequences of nucleic acids: Sequence 1: 5’- ACT GAG CGC -3’ Sequence 2: 5’- CGU AUA CAU -3’ Sequence 3: 5’- AGA GGC ATT CGC CCG -3’ Sequence 4: 5’- AUG CUA UGA AUC AAU -3’ 3A. Understanding annotation. When writing these sequences, what does the 5’- refer to in the nucleic acid structure? Be specific! (2 pts) 3B. Identify the sequences that could be examples of DNA and NOT RNA. Explain how you know this. (3 pts) 3C. Apply your knowledge of nucleic acid base pairing to predict which sequence (1, 2, 3, or 4) would bind most strongly to its complementary strand. Explain your prediction! Also include the sequence for the complementary strand. (5 pts) Copyright 2022 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.

Application. You are working in a research lab studying a new living organism from another planet. Luckily, it appears to use the same types of macromolecules for similar functions as living organisms on Earth. You have isolated four macromolecules from this organism and have run them through your analyzer to determine what atomic elements are present in each molecule. Based on your results below, which sample represents a molecule that would be responsible for storing chemical energy in this organism?
