There is external and internal so I'll list th external. The most important is skin then mucus, sweat or secretion, hair, nails and tears which are all part of the integumentary. Some internal defenses are white blood cells and T cells.
Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
I believe the answer for this would be B. Just using the process of elimination knocks out D and A, and plants make carbs not protein during photosynthesis :)
Answer:
The bottom of the cleft is in the palm domain. It is lined with beta sheet.
Explanation:
During DNA synthesis, a single DNA strand is being built in by polymerization of nucleotides. These polymerization process is catalyzed by enzymes called DNA polymerase. These DNA polymerase can be visualized as an open right hand which is composed of a thumb domain, a finger domain and a palm domain. The palm domain contains a prominent beta-sheet that forms a plate at the button of the DNA-binding cleft.
