Before the food handler handles any type of food or cooks and prepares them. It is best that they should properly wash their hands in order to prepare them with clean hands. It is best to wash the hands before handling the food so that the hand that could have exposed to dirt could be cleaned and it will prevent the food from being contaminated.
Radioactive materials that are high energy and will cause cellular and tissue damage are usually known as ; Alpha radiation.
<h3>
What is Radioactive material and Alpha Radiation ?</h3>
- Chemicals in the class of radionuclides (also known as radioactive materials) have unstable atomic nuclei. They stabilize themselves by altering the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse).
- For example, the Earth's crust naturally contains the radioactive elements uranium and thorium. These two elements slowly alter their forms over billions of years, leading to the production of decay byproducts like radon and radium. Energy is released during this process. Alpha radiation is one type of this energy.
- Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.

<span>Covered by the two cerebral hemispheres, the diencephalon is
the structure of the central nervous system that surrounds the third ventricle.
It is composed of several other structures. The most important of them are the
Thalamus, which plays a very important role in movements and emotions; and the
Hypothalamus, which provides functions including thermoregulation, appetite and
regulation of the sleep-wake cycle.</span>
Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.
