A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
<span>The
answer is bone. A new technique of
observing Harris lines (between the diaphysis and epiphysis of long bones), by
use of radiography, of bone is being used to postulate ancient diet of populations.
This is especially used to determine
stressful periods that were characterized
by poor diet (deficiencies) by comparing carbon
and nitrogen isotope ratios</span>
Answer: solid
Explanation: i remember learning this but if im wrong im sorry
Auscultation is a check-up administered in your abdomen by using a stethoscope to listen to bowel sounds. When you hear bowel sounds, then your systems are perfectly normal. When there are areas that do not produce any grumbling noises, then there must be blockage in that area.
Let's examine the area for auscultation. The diagram is shown in the picture. The abdomen is divided into four quadrants. The upper boundary is the latissimus dorsi which is the group of muscles behind the arm and stretches to the side.
The amplitude. Don't mind that other dude that attempted to answer. lol.
