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? A:
A:
output: 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? A:

OPTIONS:
- helium
- dioxide
- hydrogen
- co2

Answer: co2

Problem: OPTIONS:
- nematodes
- vegetarians
- decomposers
- omnivores
Q: 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? A:
Answer: omnivores

Problem:OPTIONS:
- metamorphosis
- creep
- leaching
- weathering

Answer the following question given this paragraph: Weathering changes solid rock into pieces. These pieces are called sediments. Sediments are described in the chapter Earth's Materials and Crust . Sediments are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments. Weathering may also cause the minerals at the Earth's surface to change form. The new minerals that form are stable at the Earth's surface. There are two types of weathering, mechanical and chemical. These are discussed in the next two concepts. Q: Over time, what changes solid rock into pieces? A:
****
A: weathering

Answer the following question given this paragraph: Today, these ideas about electrons are represented by the electron cloud model. The electron cloud is an area around the nucleus where electrons are likely to be. Figure below shows an electron cloud model for a helium atom. Q: What is the area around the nucleus of an atom where electrons are likely to be, called? A:
OPTIONS:
- electron wave
- electron membrane
- electron pocket
- electron cloud
electron cloud

Answer the following question given this paragraph: Most aquatic organisms do not have to deal with extremes of temperature or moisture. Instead, their main limiting factors are the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water. Q: Besides the concentration of dissolve oxygen and nutrients in the water, what other factor limits aquatic organisms? A:
OPTIONS:
- rainfall
- temperature
- lake size
- availability of sunlight

Answer:
availability of sunlight
