Answer:

the main causes are, infection,abdominal growth,inflammation,obstruction blockages

Explanation:

“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.

Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).

Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.

Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.

In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.

Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.

The reproductive organs of the plant are stamen, stigma, calyx, pistil, and colas.

Stamen is the male part of a flower. Stigma is responsible for collecting pollen grains. Calyx is a component of sepals and responsible for protecting the inner part of the flower while it is under development. Pistil is the female reproductive part of the flower. Cola is the bud. It is a cluster of buds. In general, the reproductive parts are the androecium (group of stamens) and gynoecium (carpels/pistils).

Answer:

H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane

Explanation:

ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.

Answer: the answer is B or during the negative feedback loop.

Explanation: the body is trying to counteract the negative feed back.

During a negative feedback loop, the body is working on counteracting an effect. thus, option B is correct.

Positive feedback loops amplify or exacerbate changes, moving a system farther from equilibrium and making it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

A self-regulating system is a negative feedback loop, often known as an inhibitory loop. Increased output from the system restricts future production in a negative feedback loop. When the quantities of particular proteins or hormones in the body get too high, the body reduces their production.

Answer:

its B. a cloud of gas and dust in space

Nebula is a cloud of gas and dust in space. The correct option is B.

A nebula is a distinct luminescent component of the interstellar medium that can be composed of ionized, neutral, or molecular hydrogen, as well as cosmic dust.

When stars form within a nebula, they emit a stream of charged particles known as stellar wind.

Massive stars and young stars have stellar winds that are much stronger than the Sun's.

When the wind collides with the gas in the nebula, it creates shock waves or hydrodynamic instabilities, which shape the gas clouds.

Nebulae are frequently star-forming regions, as seen in the Eagle Nebula's "Pillars of Creation."

Thus, the correct option is B.

The primary distinction between preganglionic and postganglionic neurons is that preganglionic neurons arise from the central nervous system and supply the ganglia, whereas postganglionic neurons arise from the ganglia and supply the tissues.

Motor neurons are brain and spinal cord cells that allow us to move, speak, swallow, and breathe by transmitting commands from the brain to the muscles that perform these functions.

Acetylcholine is used by preganglionic neurons in the sympathetic and parasympathetic nervous systems, as well as postganglionic neurons in the parasympathetic nervous system (ACh). The sympathetic nervous system's postganglionic neurons use norepinephrine and epinephrine. However, there are some exceptions, as described below.
