You are on a carnival ride that makes you very dizzy. what could be causing this?

2 answers:

8 0

Dizziness is usually caused by an upset in the balance centers of the inner ear, which is called vestibular system. This is where balance is regulated. Upsetting the vestibular balance results in brief and intense sensation of spinning. Dizziness is often initiated by rapid change in head movements. An individual may also experience dizziness because of pregnancy, headache, low or high blood pressure, etc.

Explain Gynecomastia in males.

PolarNik [594]

Gynecomastia is an increase in the size of the mammary gland in men. The condition can occur in one or both breasts. It starts as a small mass under the nipple, which can be sensitive. One breast can be bigger than the other. Its cause is an imbalance between the stimulatory effects of estrogen (female sex hormones) and the inhibitory effects of androgens (male sex hormones) in the breast tissue, when the first ones increase, or the second ones descend.

Gynecomastia is a problem relatively common in the population, and there are three prevalence peaks throughout life:

Newborns: Between 60 and 90% of newborns have gynecomastia, produced by the passage of maternal estrogens through the placenta. It is a transient gynecomastia that disappears in about 2-3 weeks.

Puberty: Gynecomastia in puberty affects mainly young people aged between 10 and 14 years, and is due to the transient and physiological increase in estrogen that occurs at this age.

Elderly: Is due to an increase in fatty tissue with a greater peripheral aromatization ( a process that occurs in adipose tissue and that involves the conversion of androgens into estrogens), a decrease in the production of testosterone by the testes and the use of drugs.

Is vitamin c prevents sore throat testable by scientific inquiry

sergey [27]

There is not enough evidence to support that <span>vitamin C aid in sore throat. But there is no harm too.

In the medical field, every treatment should be supported by evidence. This practice called evidence-based medicine. There is so much drug claim that actually wasn't supported by research and might be potentially doing more harm than benefit. Theory or argument about why it should work is not enough, you need to do a research to find the truth.</span>

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve

kkurt [141]

Answer:

The correct matches are:

In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
Since, NADH is donating its H+, it is being oxidized to NAD+.
