Biology Homework Assistance
The most challenging aspect of biology education is making students grasp the microscopic realm of biology, delving into cells and exploring genes and molecules. However, with the advent of information technology, biology homework assistance can play a crucial role when neither words nor illustrations suffice to elucidate biology concepts.
QuestionAI is an online biology learning platform that aids in learning and mastering biology concepts, featuring a variety of experiments and corresponding exercises, a departure from conventional biology question aids. Here, you can simulate experiments to replicate experimental scenarios, delving deeper layer by layer to comprehend and internalise key concepts.
- 30. The enzyme salivary amylase will act on starch but not on protein. This action illustrates that salivary amylase (1) contains starch (1) is chemically specific (3) is not reusable (4) lacks protein 31. The graph below shows the effect of tempera- ture on the relative rate of action of enzyme X on a protein. Which change would not affect the relative rate of action of enzyme X? (1) the addition of cold water when the reaction is at 50^circ C (2) an increase in temperature from 70^circ C to 80^circ C (3) the removal of when the reaction is at 30^circ C (4) a decrease in temperature from 40^circ C to 10^circ C 32. Enzymes influence chemical reactions in living systems by (1) becoming part of the product after the reactions occur (2) combining with atmospheric gases to form waste products (d) affecting the rate at which reactions occur (4) absorbing water during synthesis and digestion 33. The diagram below represents three steps in the structure X is most likely digestion of the sugar sucrose. In this diagram, (1) a molecule of oxygen (2) the end product (3) an enzyme molecule (4) the sugar 28 Tonic 2: Moments it the diagram of an enzyme-controlled cushing on your knowledge of biology. reaction - 34. Explain what is lagram. Use thing Steps 1: the following diagram. Use D, and E-to help you with your of your answer, indicate whickplanatics represent the enzyme and the product. 35. Is this reaction an illustration of synthesis or digestion? Support your answer.[1] 36. Explain why heating these molecules might __ the rate at which this reaction occurs? [1] Base your answers to questions 37 through 410 the diagram and data table below and on your knowledge of biology. A student is studying the effect of temperature on the action of a protein-digesting enzyme that's contained in stomach fluid An investigation isset up using five identical test tubes. Each test tube contains 40 milliliters of stomach fluid 40 mLd as well as a 20-millimeter glass tube filled with cooked gastrict egg white, as shown in the Glass tub diagram. After 48 hours the contain amount of egg white digested egg whit in each tube was measured. The data collected are shown in the following table. 37. Identify the independent variable in this investigation. (1) gastric fluid (2) length of glass tubing temperature (4)time
- 1. Identify which are the most common domestic plants and animals? 2. Hypothesize: why are the plants and animals so different in the Americas compared to the rest of the world?
- Cellular Respiration: Breaking down our Cellular Respiration: Breaking down Energy __ __ __ Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system that takes In nutrients, breaks them down and creates energy for the cell. The process of creating cell energy is known as respiration. Most of the chemical reactions involved in cellular respiration happen in the mitochondria. A mitochondrion is shaped perfectly to maximize its efforts. 1. What process happens in the mitochondria? 2. What is the purpose of the process in III (what does it create)? Introduction to Cellular Respiration Organisms, such as plants and algae, can trap the energy in sunlight through photosynthesis and store it In the chemical bonds of carbohydrate molecules The principal carbohydrate formed through photosynthesis is glucose. Other types of such as animals, fungl, protozoa, and a large portion of the bacteria, are unable to perform this process. Therefore, these organisms must rely on the carbohydrates formed in plants to obtain the energy necessary for their metabolic processes This means they must eat plants and other animals in order to gain energy. __ 4. Some organisms perform photosynthesis to produce energy Other organisms cannot do photosynthesis. What can __ the In animaly/criters.through the processor cellular 5. Animals and other organisms obtain the energy available in carbohydrates through the process of cellular Cells take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrates and release the energy The energy is generally not needed immediately; rather it is used to combine adenosine diphosphate (ADP)with another phosphate to form adenosine triphosphate (ATP) molecules. The ATP can then be used for processes in the cells that require energy, much as a battery powers a mechanical device During the process of cellular respiration, carbon dioxide is given off. Plant cells can use this carbon dioxide during photosynthesis to form new carbohydrates. __ disappointed 7. What is the chemical energy in the cell called? __ 8. What does ATP stand for? __ 9. What is one product of cellular respiration? __
- RECOGNIZING SIMII ARITIES AND DIF FERENCES One reading skill is the ability to recognize similarities and differences between two phrases, ideas , or things. This is sometimes known as comparing and contrasting. Read the question and write the answer in the space provided. 6. Name two ways in which fungi are similar to bacteria. __
- 1 point Which statement best describes the relationship that exists among proteins, DNA and cells? Cells contain DNA, which controls the production of proteins. Proteins-Combine to produce cells, which produce DNA. Proteins are made up of DNA, which determines the cells that are produced DNA is made up of proteins, which tell a cell how to function.
