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.
Cytoskeleton because it maintains cell's shape, secures organelles in specific positions, allows cytoplasm and vesicles to move within the cell
Answer:
the sun and earth are in different places but im not 100% sure bout it
“In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.”
<span>The
phosphorus cycle is different from the carbon cycle (and other cycles) because (1)
it is not in gas state; (2) a cycle happening only in lithosphere, hydrosphere,
and biosphere and (3) phosphorus is located in and on land, sea, and sediment.</span>
