Q: Dissolved fertilizer can ultimately lead to the creation of what in lakes or coastal oceans, which means a place where nothing can live? Read this paragraph and choose the correct option from the provided answers: Chemicals that are applied to farm fields include fertilizers and pesticides. Excess chemicals can be picked up by rainwater. The chemicals can end up in streams, ponds, lakes, or the ocean. Dissolved fertilizer causes tremendous numbers of water plants and algae to grow. This can lead to dead zones where nothing can live in lakes or the coastal oceans. Choices: - extinction zone - deceased zone - hydrothermal vent - dead zone A:
dead zone

Q: What is the name of the science that is concerned with naming and grouping organisms? Read this paragraph and choose the correct option from the provided answers: Carolus (Carl) Linnaeus (1707-1778) ( Figure below ) built on Aristotle's work to create his own classification system. He invented the way we name organisms today, with each organism having a two word name. Linnaeus is considered the inventor of modern taxonomy , the science of naming and grouping organisms. Choices: - geology - methodology - biology - taxonomy A:
(Answer)
taxonomy

Ques: Q: The nuclear envelope is a double-layered plasma membrane like the cell membrane, although without what? Read this paragraph and choose the correct option from the provided answers: Amoebozoa The amoebozoans characteristically exhibit pseudopodia that extend like tubes or flat lobes, rather than the hair-like pseudopodia of rhizarian amoeba (Figure 23.26). The Amoebozoa include several groups of unicellular amoeba-like organisms that are free-living or parasites. Choices: - cell walls - nucleic acids - cytoplasm - membrane proteins A:
Ans: membrane proteins

(Q).
Q: The remainder is transferred by contraction of what before the ventricles begin to contract? Read this paragraph and choose the correct option from the provided answers: Choices: - the arteries - the stomach - the large intestine - the atria A:
(A).
the atria

Ques:Q: Metabolic enzymes catalyze catabolic reactions that break down what? Read this paragraph and choose the correct option from the provided answers: 24.2 Carbohydrate Metabolism Metabolic enzymes catalyze catabolic reactions that break down carbohydrates contained in food. The energy released is used to power the cells and systems that make up your body. Excess or unutilized energy is stored as fat or glycogen for later use. Carbohydrate metabolism begins in the mouth, where the enzyme salivary amylase begins to break down complex sugars into monosaccharides. These can then be transported across the intestinal membrane into the bloodstream and then to body tissues. In the cells, glucose, a six-carbon sugar, is processed through a sequence of reactions into smaller sugars, and the energy stored inside the molecule is released. The first step of carbohydrate catabolism is glycolysis, which produces pyruvate, NADH, and ATP. Under anaerobic conditions, the pyruvate can be converted into lactate to keep glycolysis working. Under aerobic conditions, pyruvate enters the Krebs cycle, also called the citric acid cycle or tricarboxylic acid cycle. In addition to ATP, the Krebs cycle produces high-energy FADH2 and NADH molecules, which provide electrons to the oxidative phosphorylation process that generates more high-energy ATP molecules. For each molecule of glucose that is processed in glycolysis, a net of 36 ATPs can be created by aerobic respiration. Under anaerobic conditions, ATP production is limited to those generated by glycolysis. While a total of four ATPs are produced by glycolysis, two are needed to begin glycolysis, so there is a net yield of two ATP molecules. In conditions of low glucose, such as fasting, starvation, or low carbohydrate diets, glucose can be synthesized from lactate, pyruvate, glycerol, alanine, or glutamate. This process, called gluconeogenesis, is almost the reverse of glycolysis and serves to create glucose molecules for glucose-dependent organs, such as the brain, when glucose levels fall below normal. Choices: - proteins - lipids - impurities - carbohydrates A:

Ans:carbohydrates

Ques: Q: What is another word for saturated hydrocarbons? Read this paragraph and choose the correct option from the provided answers: Saturated hydrocarbons contain only single bonds between carbon atoms. They are also called alkanes. They may form straight-chain, branched-chain, or cyclic molecules. Compounds with the same number of atoms but different shapes are called isomers. Choices: - catalysts - enzymes - aldehydes - alkanes A:
Ans:
alkanes
