Answer:
the bones belong to an adult female
Explanation:
A female pelvic bone is thinner and lighter while the male pelvic is thicker and heavier. The female pelvic bone has a wider and round shape inlet mainly to deliver babies. The inlet of the male pelvic bone is narrow and normally has a heart shape.
The sciatic notch is a large notch in the pelvis located above the ischial spine. In females, this sciatic notch is wider whereas in males, it is narrower. The subpubic angle is located at the inlet of the pelvic. In females the subpubic angle is wider and it is narrower in males
Answer:
The skeletal system provides a frame to
support and protect the body and allows the
body to move.
Atoms contain a nucleus and orbitals. Protons and neutrons are within the nucleus and electrons are in the orbitals. The number of protons represents the atomic number. The atomic mass is the sum of the protons and neutrons. When the number of neutrons differ, it is called an isotope, like C12, C13, C14. The number of neutrons affect the stability.
Answer:
Bulk flow of gases and solutes works well over long distances, whereas diffusion is effective only over very short distances.
The rate of oxygen transport by diffusion across the lungs must generally match the rate of transport by the circulatory system.
Explanation:
The respiratory system is responsible for the intake of oxygen and removal of CO2 from the body while the cardiovascular system is responsible for the transport of these respiratory gases and other substances such as nutrients, wastes, hormones all over the body. To ensure their coordination, the rate of gaseous exchange at the lungs should match the rate of blood flow in blood vessels.
Bulk flow and diffusion are the passive processes responsible for the transport of solutes and respiratory gases in the body. Diffusion moves the gases and substances down their concentration gradient but is effective over shorter distances only. Bulk flow moves a large number of substances in the same direction from the region of higher pressure to their lower pressure. Since diffusion can not transport the substances all over the body and is a relatively slow process, other processes such as bulk flow assist in transport.
