Two layers of phospholipid molecules make up most of the cell membrane in the cells of living things. Q: What are lipids that contain phosphorus called? Choices: - amino acids - alkaloids - eukaryotes - phospholipids A:
(Answer)
phospholipids
Ques: Answer the following question given this paragraph: CHAPTER REVIEW 17.1 An Overview of the Endocrine System The endocrine system consists of cells, tissues, and organs that secrete hormones critical to homeostasis. The body coordinates its functions through two major types of communication: neural and endocrine. Neural communication includes both electrical and chemical signaling between neurons and target cells. Endocrine communication involves chemical signaling via the release of hormones into the extracellular fluid. From there, hormones diffuse into the bloodstream and may travel to distant body regions, where they elicit a response in target cells. Endocrine glands are ductless glands that secrete hormones. Many organs of the body with other primary functionssuch as the heart, stomach, and kidneysalso have hormone-secreting cells. Q: The endocrine system consists of cells, tissues, and organs that secrete what critical to homeostasis? Choices: - antibodies - acids - saliva - hormones A:
Ans: hormones

Answer the following question given this paragraph: NaN3 is 1.847 g/cm . What is the volume of the gas produced compared to the solid reactant? Suggest a plausible reason to explain why skin burns can result from the inflation of an airbag during an automobile accident. Under basic conditions, the reaction of hydrogen peroxide (H 2O2) and potassium permanganate (KMnO4) produces oxygen and manganese dioxide. During a laboratory exercise, you carefully weighed out your sample of KMnO4. Unfortunately, however, you lost your data just before mixing the KMnO 4 with an H2O2 solution of unknown concentration. Devise a method to determine the mass of your sample of KMnO4 using excess H2O2. Carbonated beverages are pressurized with CO 2. In an attempt to produce another bubbly soda beverage, an intrepid chemist attempted to use three other gases: He, N 2, and Xe. Rank the four beverages in order of how fast the drink would go "flat" and explain your reasoning. Which beverage would have the shortest shelf life (i. , how long will an unopened bottle still be good)? Explain your answer. ♦️ Urea is synthesized industrially by the reaction of ammonia and carbon dioxide to produce ammonium carbamate, followed by dehydration of ammonium carbamate to give urea and water. This process is shown in the following set of chemical equations:. Q: What are carbonated beverages pressurized with? Choices: - helium - dioxide - hydrogen - co2 A:
(A).
co2
Ques:Answer the following question given this paragraph: Some mammals are strictly herbivores or strictly carnivores . However, most mammals will eat other foods if necessary. Some mammals are omnivores . They routinely eat a variety of both plant and animal foods. Most mammals also feed on a variety of other species. The few exceptions include koalas, which feed only on eucalyptus plants, and giant pandas, which feed only on bamboo. Types of mammalian diets and examples of mammals that eat them are given in Table below . How would you classify your own diet?. Q: Mammals are either herbivores, carnivores or what? Choices: - nematodes - vegetarians - decomposers - omnivores A:

Ans:omnivores
Ques:Answer the following question given this paragraph: Bacteria in food or water usually can be killed by heating it to a high temperature. Generally, this temperature is at least 71 C (160 F). Bacteria on surfaces such as countertops and floors can be killed with disinfectants, such as chlorine bleach. Bacterial infections in people can be treated with antibiotic drugs . These drugs kill bacteria and may quickly cure the disease. If you've ever had strep throat, you were probably prescribed an antibiotic to treat it. Q: What helps treat bacterial infections in people? Choices: - respiratory drugs - vaccines - rest - antibiotic drugs A:

Ans:
antibiotic drugs
