22 answer is: Molecules in food contain chemical energy that cells use to produce Adenosine triphosphate ATP.

23 answer is:  masticating

24 answer is: Absorptive

25 answer is: autonomous nervous system

26 answer is: a neuromuscular junction.

27 answer is: tendons

28 answer is: integumentary system

29 answer is: adrenal gland

30 answer is: Antigens

Explanation:

22 explanation is: Respiration is that the method by that cell get energy within the sort of ATP. Adenosine triphosphate captures energy obtained from the breakdown of food molecules and releases it to fuel alternative cellular processes.

23 explanation is : The teeth play an important role in masticating (chewing) or physically breaking food into smaller particles. The enzymes present in saliva also begin to chemically break down food. The food is then swallowed and enters the esophagus—a long tube that connects the mouth to the stomach.

24 explanation is : Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food.  The inside of the small intestine has many folds, called villi.

25 explanation is : When a person is unconscious due to head injury, but the autonomous nervous system of the body keeps the body function normal by ensuring the flow of information between the brain and the rest of the body part.

26 explanation is : A single motor neuron with all the muscle cells it innervates is called a: Motor unit.

27 explanation is : Many skeletal muscles are attached to the ends of bones that meet at a joint.

28 explanation is : The organs of the integumentary system are the skin, hair, and nails.

29 explanation is : The adrenal gland is the gland that produces hormones that cause you to feel frightened during a horror movie.

30 explanation is : When your body is infected with the cold virus, antibodies tag the pathogen’s antigens, which are found on their outer surface, for destruction by immune cells.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
