Answer:
Is a bone marrow biopsy painful? Most people need only local anesthesia, as bone marrow aspiration, in particular, can cause brief, but sharp, pain. Individuals are fully awake during the procedure, but the aspiration and biopsy site will be numbed to reduce pain.
Answer:
True
Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).
Answer:
Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells.

Whole body: chills, fatigue, fever, night sweats, shivering, or sweating

Answer:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.
