<span>Tight junctions, at the site of a tight junction, cells are held tightly against each other by many individual groups of tight junction proteins called claudins, each of which interacts with a partner group on the opposite cell membrane. For example, the tight junctions between the epithelial cells lining your bladder prevent urine from leaking out into the extracellular space.</span>
Explanation:
The rock cycle is powered by the internal and the external heat engines.
The sun is the ultimate source of energy that drives surface processes.
The heat from radioactive decay, frictional heat, accreted heat during the formation of the earth all combines to drive subsurface event.
- Surface events that impacts the rock cycle are weathering, erosion, transportation and deposition of sediments.
- Surface events leads basically to the production of sediments.
- The agents that drives the production of these materials are the wind, water and glacier.
- The sun is the major drive for the formation of these agents.
- The process leads to the formation of sedimentary rocks
For the subsurface process, the internal heat engine provides the energy that powers the convection current within the mantle.
This process leads to the formation of igneous and metamorphic rocks.
Where plates diverges and converges, igneous rocks form due to the upwelling of magma.
At convergent margin, a subduction zone allows for the changing of rock type into a metamorphic one. This is due to the temperature and pressure in those areas.

A dog's stomach acid is stronger than ours so they can digest bigger chunks of food unlike us superior humans lol
Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
