Gamma leaves the body quickly so minimizes damage to tissue and can be detected using scintillation devices.

<h3>What is the effect of gamma rays on tissue?</h3>

Gamma rays can completely permeate the human body and cause ionizations that can damage DNA and tissue.

The most hazardous methods of exposure to radioactive elements that release alpha and beta particles are ingestion, inhalation, absorption, and injection. The most damaging external threat is gamma radiation. "Beta burns" can result from beta particles partially penetrating skin.

<h3>How do gamma rays destroys cell?</h3>

They produce indiscriminate chemical reactions due to their extremely high degrees of chemical reactivity. The several molecules that make up the cell are damaged as a result of radiation and the battered electrons' chaotic movement inside the cell. Additionally, chromosomal DNA within the cell nucleus may sustain damage.

Drupady [299]

Answer:

The given statement is TRUE

Explanation:

Urinary bladder is the hollow, muscular and distensible (elastic) organ in the urinary system of a human. The urine enters the bladder through the ureters from the kidneys. The urine collected in the bladder expands it.

The urinary bladder is made up of transitional epithelium. Once the urinary bladder is expanded to a certain extent it stimulates the stretch receptors in the transitional epithelium for the excretion of urine through the urethra.

Therefore, when the urine is accumulated in the urinary bladder, the bladder distends or expands and stimulates the stretch receptors in the transitional epithelium for urine excretion.

Tuberculosis

Mycobacterium tuberculosis is the bacteria that causes tuberculosis (TB). Although TB germs typically assault the lungs, they can also affect the kidney, spine, and brain. Not every person who contracts TB germs gets ill. Latent TB infection (LTBI) and TB disease are consequently two TB-related diseases. TB disease can be lethal if it is not adequately treated.

Infections of tuberculosis, once uncommon in wealthy nations, started rising in 1985, in part due to the appearance of HIV, the virus that causes AIDS. HIV impairs the immune system, making it incapable of warding off TB pathogens. In the United States, tuberculosis started to decline once more in 1993 as a result of more effective control initiatives. But it still raises questions.

Classify each characteristic of grains as refined grain or whole grain.
mylen [45]
