A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell
Sickle cell is a disorder that affects the
molecules in the red blood cells, particularly the hemoglobin. The hemoglobin
is the molecule responsible for transporting oxygen throughout the body. When a
person has sickle cell anemia, the red blood cells are distorted crescent
shapes that do not travel in the bloodstream properly and efficiently. As a
result, this disorder hampers the distribution of oxygen throughout the body.

pain. The severity of this condition varies from person to person but is common
in African descents. </span>
Answer:
0 joules
Explanation:

Explanation:
All animals have collagen. Collagen is found exclusively in all animals. It is the main structures protein that is found in the connection tissues of animals.
Animals do possess embryos that undergoes gastrulation where the digestive cavity and germ layers are formed, these then develop into certain tissue systems, organs etc
Animals are heterotrophs in that they are unable to symthesize their own food but rather depend on plants which are autotrophs for their food and they also lack cell wall which differentiates them from plants. Not all animals are mobile for example, sponges.
