Answer: The information can be obtained from an expert phlebotomist or through an internet.
<u>Explanation:</u>
The Phlebotomist is one who is trained especially for taking out blood from the veins of patients. Such blood samples are used for testing purposes. If a phlebotomist is new and has no idea regarding collecting a D-dimer or an HIV test then in that case, he can take the help of another phlebotomist who is an expert in collecting such samples.
Such expert the phlebotomist will guide him properly in it. A new phlebotomist might read a book on such tests or can collect information from the internet also. This will resolve his problem.
Answer: No he's not telling her the truth
Explanation: There's never a guarantee of not having it. There's always at least a 0.000000001% chance of having any disease.
Answer:
1. E) During muscle contraction all of the answers above are correct.
2. A) Myosin pulls actin filaments toward the M disk.
Explanation:
The mechanism of muscle contraction is also known as the sliding filament theory. It explains the activities which occur during contraction of muscles.
Muscles are made up of functional units called sarcomeres and these sarcomeres made up of myofibrils which are long and thin strands of protein. Myofibrils contain thin filaments called actin and thick filaments called myosin. Interactions between the thin and thick filaments results in contraction.
The I band contains thin filaments. The H band is the area of no thin filaments. The M line is the midline of the thick filaments. The Z line is the boundary between adjacent sarcomeres and the A band is the area of thick filaments.
Contraction occurs when muscle fibres are activated by neurons through the release of calcium ion. On stimulation, the H and I band get smaller, the zone of overlap gets larger and the Z lines move closer together and the A band remains constant. This the thin filaments slide towards the center resulting in the shortening of the sarcomeres and the muscle fibres as a whole.
One way health problems can be addressed is through <u>technology</u>, which includes the use of computers, lasers, and other revolutionary techniques.
<h3>How has technology helped us solve health-related problems?</h3>
Over the years, we've seen an increase in technological advancement which has been beneficial in solving problems related to medical and health sectors.
Some of these solution processes involves the use of computers in:
- Storing, and retrieving information about patients' health.
- The use of AI and technological devices to carry out appropriate medical treatment for patients. etc
