Answer the following question given this paragraph: Respiration is the process in which gases are exchanged between the body and the outside air. The lungs and other organs of the respiratory system bring oxygen into the body and release carbon dioxide into the atmosphere. Q: What is the process in which gases are exchanged between the body and the outside air? Choices: - ingestion - metabolism - precipitation - respiration A:
respiration

Answer the following question given this paragraph: Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics. A number of genes factor into determining a person's natural skin color, so modifying only one of those genes changes the color only slightly. It is currently thought that at least three separately inherited genes contribute to skin pigmentation. Let's call these three genes A, B, and C. A, B, and C are incompletely dominant to a, b, and c, with A, B, and C each contributing a "unit of darkness" to the phenotype. Therefore an AABBCC individual is very dark, darker than an AaBbCc individual, and much darker than a aabbcc individual. A person may have as many as 6 "dark units" to as few as no "dark units," and any combination in between. This will result in a phenotypic spectrum of color gradation. When graphed, a phenotypic spectrum usually results in a bell-shaped curve, with extreme phenotypes on both ends and more common phenotypes in the center of the curve. Q: Human skin color is primarily due to the presence of what pigment in the skin? Choices: - tannin - melatonin - cytoplasm - melanin A:
(Answer)
melanin
Ques: Answer the following question given this paragraph: Producers such as plants or algae use carbon dioxide in the air to make food. The organisms combine carbon dioxide with water to make sugar. They store the sugar as starch. Both sugar and starch are carbohydrates. Consumers get carbon when they eat producers or other consumers. Q: Sugar and starch are examples of what type of nutrient? Choices: - proteins - fat - vitamins - carbohydrates A:
Ans: carbohydrates

Answer the following question given this paragraph: 9.4 | Translation By the end of this section, you will be able to: Describe the different steps in protein synthesis Discuss the role of ribosomes in protein synthesis Describe the genetic code and how the nucleotide sequence determines the amino acid and the protein sequence The synthesis of proteins is one of a cell's most energy-consuming metabolic processes. In turn, proteins account for more mass than any other component of living organisms (with the exception of water), and proteins perform a wide variety of the functions of a cell. The process of translation, or protein synthesis, involves decoding an mRNA message into a polypeptide product. Amino acids are covalently strung together in lengths ranging from approximately 50 amino acids to more than 1,000. Q: With the exception of water, what accounts for more mass than any other component of living organisms? Choices: - hormones - nervous tissue - fats - proteins A:
(A).
proteins
Ques:Answer the following question given this paragraph: Secondary succession occurs in a formerly inhabited area that was disturbed. Q: What occurs when a former inhabited area gets disturbed? Choices: - tertiary succession - primary succession - tropical succession - secondary succession A:

Ans:secondary succession
Question: Answer the following question given this paragraph: All living things are made of matter . In fact, matter is the "stuff" of which all organisms are made. Anything that occupies space and has mass is known as matter. Matter, in turn, consists of chemical substances. It is the carbons, hydrogens, oxygens and other elements that combine to form molecules, compounds, organelles, cells and eventually tissues, organs and organisms. In addition to being made of matter, all living organisms also need energy to survive. Q: Anything that occupies space and has mass is known as what? Choices: - opaque - solid - dense - matter A:
Answer:
matter
