It is false that portable alcohol breath testing devices cannot be used for persons under the age of 21".
Accuracy depends on the sample of breath being deep lung air (alveolar air). As the driver breathes out, the device continuously monitors the expired air using an infrared cell. The concentration of ethanol climbs as expiration continues, and when the level of ethanol stabilizes, the sample of breath is analyzed.
Attach a mouthpiece to the breathalyzer. Press and release the power button. Wait for the unit to warm up to optimal test conditions until the display shows "blow". Blow into the mouthpiece for approximately 4 seconds.
Therefore, the correct answer will be " it is false that portable alcoholbreath testing devices cannot be used for persons under the age of 21".

B. undernutrition.
C. overnutrition.
D. glaucoma
Consuming inadequate calories or having a deficiency in certain vitamins or minerals is known as undernutrition. The correct option is B. Undernutrition occurs when the body does not receive enough essential nutrients to maintain proper growth, development, and overall health.
It can lead to various health issues, including malnutrition, stunted growth, weakened immune system, and impaired cognitive function. Undernutrition is a significant concern, particularly in areas with food scarcity or limited access to a balanced diet.
Addressing undernutrition is crucial for ensuring proper growth, development, and overall health of individuals and communities. It requires a coordinated effort from governments, healthcare organizations, non-governmental organizations (NGOs), and the community to provide sustainable solutions and improve nutrition for those in need.

Explanation:
Cells and tissues are both fundamental components of living organisms, but they serve different roles and have distinct characteristics:
Cells:
Cells are the basic structural and functional units of life.
They are the smallest living entities in the body.
Cells can perform a wide range of functions depending on their type, such as nerve cells transmitting signals, muscle cells contracting, or blood cells transporting oxygen.
Cells can exist independently as single-celled organisms (e.g., bacteria) or as part of multicellular organisms.
The human body is composed of trillions of cells with various specialized functions.
Tissues:
Tissues are groups of similar cells that work together to perform specific functions.
Tissues are formed when multiple cells of the same type come together and organize themselves to carry out a particular task more efficiently.
There are four primary types of tissues in the human body: epithelial tissue (covering and lining), connective tissue (support and protection), muscle tissue (movement), and nervous tissue (communication and control).
Tissues are organized into organs, and organs work together to form organ systems, ultimately contributing to the functions of the entire organism.
In summary, cells are the fundamental units of life and can exist independently or as part of tissues. Tissues, on the other hand, are groups of similar cells organized together to perform specific functions within an organism. Cells make up tissues, and tissues, in turn, make up organs and organ systems in complex multicellular organisms.
Sanitation is a way that both individuals and communities can help prevent the spread of communicable diseases.
Further Explanation:
Many pathogen or organism is present inside or outside the body. Sometimes they are harmful. Communicable diseases are mainly developed in an individual due to the presence of microorganisms such as viruses, fungi, and parasites. These microorganisms can be present inside the body and can be present in the exterior environment. These communicable diseases can be passed to one being to another being through the contaminated water and food. These microorganisms can cause fever, diarrhea, and vomiting. These communicable diseases can be prevented through proper sanitation. It is a significant prospect for all individuals to maintain proper health and increase their life span. Though it is important for infants below five years old, it also helps in maintaining proper health for all individuals. It prevents the transmission of communicable diseases such as diarrhea, dysentery, and others.
