The answer is; Physical weathering does not change the composition of the rock while chemical weathering does.
Physical weathering only cracks and breaks the rocks into smaller pieces. Chemical weathering causes a reaction between the rock minerals and acidic rain or organic acids from plants forming different minerals or dissolving the rock minerals.
Answer:
Hypothesis: If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue.
Explanation:
In a scientific research the hypothesis is an assumption, a possibility that will justify the purpose of the scientific research and will help in the establishment of all the steps of this research, so that it is possible to determine if the hypothesis is true or false. In other words, we can say that the hypothesis must be formulated as an assumption, before the research that will prove it or not.
An example of a hypothesis about research on the longevity of cells that line the esophagus is: "If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue."
Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
Answer:
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
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.<span> 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. </span>
