The correct answer is - a front.
On this image, the lines are representing a front, and since the signs are marked with blue color, it means that it is a cold front. The fronts are advancing masses of air. In this case, we have a cold front, thus we have advancing cold air masses in the western part of the US, and in the Great Lakes region and the northeastern part of the country. This means that these areas will be affected by colder air masses, that will bring in higher air pressure, colder weather, and cold winds from the direction from which these cold fronts are coming.
Answer:
The energy that was not passed on the next tropic level is lost as heat
Explanation:
In an ecosystem flow of energy occur from one tropic level to the next one as the organism of one tropic level eats another organism belongs to the tropic level that is lower from that of previous one.
The 10% of total energy of one tropic level is passed to the next tropic level the rest of the energy is lost as heat in the environment.
Tight junctions are cell junctions that seal tissues. These junctions form protective and functional barriers.
- The cell junction that is involved in creating a barrier between cells is the TIGHT junction.
- The tight junctions are cell-cell adhesion structures implicated in cell polarity and signaling.
- On the other hand, adherens junctions are cell junctions required for maintaining contact inhibition.
- Finally, desmosomes are intercellular junctions that bind intermediate filaments of the cytoskeleton with cadherin proteins.
