Sickle-cell disease can result.
Hope this helped you.
Answer:
A rock's exposure to the weathering elements and its surface area can affect its rate of weathering. Rocks that are constantly bombarded by running water, wind, and other erosion agents, will weather more quickly. Rocks that have a large surface area exposed to these agents will also weather more quickly.
Explanation:
Properties of the Parent Rock ;
- The mineralogy and structure of a rock affects it’s susceptibility to weathering.
- Different minerals weather at different rates. Mafic silicates like olivine and pyroxene tend to weather much faster than felsic minerals like quartz and feldspar. Different minerals show different degrees of solubility in water in that some minerals dissolve much more readily than others. Water dissolves calcite more readily than it does feldspar, so calcite is considered to be more soluble than feldspar.
-
A rock’s structure also affects its susceptibility to weathering. Massive rocks like granite generally to not contain planes of weakness whereas layered sedimentary rocks have bedding planes that can be easily pulled apart and infiltrated by water. Weathering therefore occurs more slowly in granite than in layered sedimentary rocks.
The major problem with using foreign cells grown in culture for transplantation in humans is the host immune system would destroy such cells.
The body of your child is shielded from external invaders by the immune system. These include poisons, bacteria, viruses, fungus, and other types of germs (chemicals made by microbes). The various organs, cells, and proteins that make up the immune system cooperate with one another. Infections like measles, mono (mononucleosis), and the flu virus can also temporarily impair immunity. Additionally, unhealthy eating habits, alcoholism, and smoking might impair your immune system.
Antigens, which are proteins on the surface of the invading cells, are used by the immune system to identify invaders. Every substance or cell has a unique set of antigens, and every person's cells include "self-antigens" that are particular to that person.

<span>amylase is an example of an enzyme</span>
In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.
