Answer:
Digestion
Explanation:
The breakdown of foods into forms that can be transported to cells and absorb into these cells(this process has two parts): Mechanical(breaks down large pieces of food into smaller ones) and Deglutition(swallowing).
You will suffer a variety of painful symptoms, including indigestion, bloating, and stomach discomfort, if your digestive system isn't in good shape.
What are the important component of digestion?
The process of physically and enzymatically converting food into chemicals that may be absorbed into the bloodstream is called digestion.
The gastrointestinal tract is composed of the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine, and anus.
The secret to comprehending how digestion functions is to be aware of how these organs cooperate to break down food. Beginning in the mouth, the digestive process.
Therefore, The digestive system is crucial to your overall health since it provides your body with nutrients.

What are the 4 ways or mechanisms by which a planet or moon can gain an atmosphere?
Four processes—outgassing, evaporation, sublimation, and surface ejection—can help a planet or moon to gain an atmosphere.
1) Outgassing: The release of a gas that has been dissolved, trapped, frozen, or absorbed in a substance is known as outgassing.
The outgassing that took place as the smaller, inner planets cooled down is likely how they acquired their atmospheres (volcanoes).
2) Evaporation : The process of converting anything from a liquid or solid state to vapors is called evaporation (like fog, mist, or steam).
So upon evaporation, water converts into gas and that's how moon gain an atmosphere by evaporation.
3) Sublimation : Converting a solid directly into a gas without first going through a liquid phase.
4)Surface ejection: A surface ejection is a massive discharge of plasma and magnetic field into the heliosphere from the Sun's corona.

What is the composition of the tracts in the cns that link the brain with the rest of the body?
Tracts in the CNS that link the brain with the rest of the body are composed of sensory and motor pathways.
Neural pathways called tracts can be found in the brain and spinal cord (central nervous system). Each tract runs bilaterally, either in a hemi section of the spinal cord or on each side of the cerebral hemisphere. A few of the tracts decussate, or crossover, to move downward or upward on the obverse side.Neurons synapsing onto one another create tracts, and based on where and how they are arranged inside the tract, these neurons can be categorized as first-order, second-order, or third-order neurons.Sensory neurons and motor neurons are both a part of the peripheral nervous system (PNS), which is made up of neurons and neuronal fragments outside of the central nervous system.

About how many total atp equivalents are generated by the complete oxidation of one molecule of acetyl coa?
Around 12 ATP equivalents are generated by the complete oxidation of one molecule of acetyl CoA.
Glycolysis begins when glucose enters, producing 2 pyruvate molecules. These pyruvates are subsequently transformed into two molecules of acetyl CoA. With each acetyl CoA that enters the citric acid cycle, three NADH (9 ATP), one FADH (2 ATP), and one GTP are produced (1 ATP). Each mole of acetyl-CoA will therefore yield 12 ATP molecules in total.
Electron transport from the citric acid cycle's energy precursors in step 3 causes oxidative phosphorylation, which phosphorylates ADP to produce ATP. In animals the majority of the energy required in biosynthesis, preserving appropriate ion balance, and mechanical work comes from oxidative phosphorylation.

Why does strength and contrcation increase somwhat after a few stimulation/contraction events?
The muscle generates stress during the contraction phase, which is accompanied by the cycling of the cross bridges. During the relaxation phase, the muscle lengthens back to normal.
All of the muscle fibers connected to that motor neuron will contract as an action potential moves down the motor neuron. A muscle twitch is the contraction caused by a single action potential. A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase. The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle. This period of time is necessary for calcium to diffuse out of the SR, bind to troponin, transfer tropomyosin away from the active sites, build cross bridges, and pick up any slack in the system.learn more about contraction phase here: https://brainly.com/question/26765109

During the t wave of the electrocardiogram, the ventricles are electrically repolarizing and functionally relaxing.
The T Wave shows ventricular repolarization when the ventricles relax after contracting and depolarizing. The ST segment shows the period between ventricular depolarization and repolarization, which is the space (a flat or slightly upcurved line) between the S wave and the T wave.
Although absent or downward sloping ST segments may suggest myocardial ischemia, a raised ST segment is the typical sign of myocardial infarctions. The U wave, which denotes the repolarization of the Purkinje fibres, comes after the T wave.

What differences did you observe in the structure of an artery versus the structure of a vein?
Arteries Larger, more muscular and more elastic, carry oxygenated blood from the heart, with the exception of the pulmonary artery. The blood has more pressure from the heart. Veins Under less pressure, so valves are needed. They are less strong than arteries and appear more floppy.
Arteries have thick, elastic, muscular walls whereas veins have thin walls with few elastic fibers. Arteries need these properties to give them the strength and elasticity needed to cope with the high pressure surges of oxygenated blood coming from the heart. Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries.

The active fraction of soil organic carbon largely accounts for which of the benefits of adding organic matter to soils?
Water-holding capacity, nutrient mineralization, biological activity, and water and air infiltration rates are the active fraction of soil organic carbon.
By enhancing the physical, chemical, and biological processes in the soil, organic matter contributes significantly to crop productivity and soil health. A soil's structure, water-holding capacity, nutrient mineralization, biological activity, and rates of air and water infiltration all benefit from higher amounts of organic matter.Increased tilth or soil structure is a result of higher soil organic carbon, which increases physical stability. This lowers the risk of erosion and nutrient leaching while increasing soil aeration (the amount of oxygen in the soil) and water drainage and retention. Although it only makes up 10 to 20 percent of the total organic matter in the soil, active organic matter is an essential component because it promotes microbial activity and releases nutrients into the soil.Learn more about soil organic carbon here brainly.com/question/21026038
