Either fibrillation or Cardiac Arrest
Answer:
b. aggregate abnormally to form fibers and cannot adequately carry oxygen
Explanation:
The sickle cell hemoglobin is an abnormal form of hemoglobin. As the sickle cell hemoglobin release oxygen to the interstitial fluid, it forms long, stiff, and rod-like fibers. These aggregates of hemoglobin tend to bend the erythrocyte into a sickle shape. The sickled erythrocytes rupture easily and do not move easily through blood vessels. Sickled cells tend to stick together and form clumps which in turn cause blockages in blood vessels. Therefore, the presence of sickle cell hemoglobin adversely affects the ability of RBCs to carry oxygen.
Yes! a region of the body with greater sensory acuity to have cutaneous receptors with large receptive fields, or small receptive fields.
The sensory receptor located in the skin is known as a cutaneous receptor ( the dermis or epidermis). The somatosensory system includes them. Mechanoreceptors (pressure or distortion), nociceptors (pain), and thermoreceptors are cutaneous receptors (temperature). The lowest spatial resolution is found in the thigh and calf area, whereas the fingertips have the highest spatial resolution (and the smallest receptive fields) (and largest receptive fields). Two-point discrimination threshold measurements can be used to assess the spatial resolution in response to light touch stimuli.

#SPJ4
Carbon is four valence electrons they bond to the other carbon atoms
Answer:
Option B, O2
Explanation:
It is because the oxygen released during the process of photosynthesis comes from the water absorbed by the roots and not by the CO2containing heavy oxygen (18O). In fact oxygen from CO2 containing heavy oxygen (18O) is used in making sugar which is then stored for energy.
Hence, option B is correct
