Answer the following question given this paragraph: Outcomes of Glycolysis Glycolysis starts with glucose and ends with two pyruvate molecules, a total of four ATP molecules and two molecules of NADH. Two ATP molecules were used in the first half of the pathway to prepare the six-carbon ring for cleavage, so the cell has a net gain of two ATP molecules and 2 NADH molecules for its use. If the cell cannot catabolize the pyruvate molecules further, it will harvest only two ATP molecules from one molecule of glucose. Mature mammalian red blood cells are not capable of aerobic respirationthe process in which organisms convert energy in the presence of oxygenand glycolysis is their sole source of ATP. If glycolysis is interrupted, these cells lose their ability to maintain their sodium-potassium pumps, and eventually, they die. The last step in glycolysis will not occur if pyruvate kinase, the enzyme that catalyzes the formation of pyruvate, is not available in sufficient quantities. In this situation, the entire glycolysis pathway will proceed, but only two ATP molecules will be made in the second half. Thus, pyruvate kinase is a rate-limiting enzyme for glycolysis. Q: What process starts with glucose and ends with two pyruvate molecules, a total of four atp molecules and two molecules of nadh? Choices: - secretion - absorption - photosynthesis - glycolysis A:
glycolysis

Answer the following question given this paragraph: Earth has a magnetic field ( Figure below ). The magnetic field has north and south poles. The field extends several thousand kilometers into space. Earth's magnetic field is created by the movements of molten metal in the outer core. Q: What type of field does earth have? Choices: - atmospheric - seismic - force field - magnetic A:
(Answer)
magnetic
Ques: Answer the following question given this paragraph: Cutting down on the use of chemical fertilizers is one way to prevent dead zones in bodies of water. Preserving wetlands is also important. Wetlands are habitats such as swamps, marshes, and bogs where the ground is soggy or covered with water much of the year. Wetlands slow down and filter runoff before it reaches bodies of water. Wetlands also provide breeding grounds for many different species of organisms. Q: Cutting down on the use of chemical fertilizers and preserving wetlands are ways to prevent what "unlivable" regions in bodies of water? Choices: - inhabitable zones - hostile zones - fresh zones - dead zones A:
Ans: dead zones

Answer the following question given this paragraph: People have long known that the characteristics of living things are similar in parents and their offspring. Whether it's the flower color in pea plants or nose shape in people, it is obvious that offspring resemble their parents. However, it wasn't until the experiments of Gregor Mendel that scientists understood how characteristics are inherited. Mendel's discoveries formed the basis of genetics , the science of heredity. That's why Mendel is often called the "father of genetics. " It's not common for a single researcher to have such an important impact on science. The importance of Mendel's work was due to three things: a curious mind, sound scientific methods, and good luck. You'll see why when you read about Mendel's experiments. Q: Who is called the father of genetics? Choices: - Nostradamus - Vincent van Gogh - raphael - mendel A:
(A).
mendel
Ques:Answer the following question given this paragraph: Gymnosperms are seed plants that produce naked seeds in cones. There are about 1000 species of gymnosperms. Conifers are the most common group of gymnosperms. The spruce tree in Figure below is an example of a conifer. Q: What are seeds plants that produce naked seeds in cones called? Choices: - cytoplasm - lipids - angiosperms - gymnosperms A:

Ans:gymnosperms
Ques:Answer the following question given this paragraph: CHAPTER SUMMARY 42.1 Innate Immune Response The innate immune system serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body. Using a combination of cellular and molecular attacks, the innate immune system identifies the nature of a pathogen and responds with inflammation, phagocytosis, cytokine release, destruction by NK cells, and/or a complement system. When innate mechanisms are insufficient to clear an infection, the adaptive immune response is informed and mobilized. Q: What serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body? Choices: - cells immune system - super immune system - immense immune system - innate immune system A:

Ans:
innate immune system
