Waters high heat protects organisms in ocean from what
Alja [10]

Answer:

Water's high specific heat allows it to absorb a large amount of heat without changing much in temperature, keeping a relatively constant temperature in oceans and lakes which is beneficial to marine life. If water did not have a high specific heat, then it would increase in temperature very quickly and oceans and lakes would have drastic changes in temperature in very short periods of time. This could harm or kill the organisms living in them.

If, and only blood sugar levels rise past a certain point, the cells will release a hormone called insulin. Insulin acts as a/an
lakkis [162]

Answer:

When blood glucose level rises beyond the threshold levels, the pancreas secrets hormones insulin. The latter ensures entry of  glucose into the cells through Glut transporters for cellular utilization, therefore reducing the blood levels., and promotes storage as glycogen in the liver and muscles.  

How ever if  the glucose levels drops below the  set point, an hormone glucagon is also produce by the pancreas to cause the liver o withdrawal and breakdown glucose storage as  glycogen back to glucose thus raising the blood glucose level back to the normal levels.

This is an example of negative feedback mechanism, because the increase in the input levels (blood glucose levels) brings about a counter  mechanisms (insulin secretions)as output , to reduce the  elevated   levels by promoting  entry into the cells,, thus bringing the levels to threshold levels.

Thus insulin is acting in a negative feedback mechanism to control blood glucose levels

What results when there is very heavy competition between two species??
BlackZzzverrR [31]
When there is heavy competition between two species these results may surface. First, even if there is just a little advantage of one species, the tendency is the best competitors will dominate the other. This may lead to the extinction of the weaker species. Another result is, competition may cause the traits of the competing species to evolve. This result is called character displacement. This is what happens when for instance the species live in the same area and have the same and common niche; the characteristics of the species evolve in order for them to minimize niche overlap. This is also for them not to have competitive exclusion. To add to that, when there is heavy competition, the finite resources will not be enough for all competitors who have all access to the resources. This may lead to very low survival rates.

1. How do artificial stabilization and development impact shorelines? Explain.
lora16 [44]

Explanation:

1.

Natural shorelines are the undeveloped fringe areas along the edge of a waterbody, which connect the shallow aquatic portion of the waterbody with adjacent upland. These riparian areas provide important environmental functions, such as regulating water quality (including temperature, clarity, nutrients, and contaminants) and sustaining critical habitat for a variety of aquatic and terrestrial organisms (including invertebrates, fish, amphibians, reptiles, shorebirds and waterfowl, and mammals).

For decades, "traditional" shoreline stabilization methods have centered on "hard" construction approaches such as vertical concrete, metal, or wood break-walls, gabions (stone-filled wire baskets) and rip rap (loose rocks or stones). Biologists and engineers now realize that in addition to creating a physical barrier, these hardened vertical or near-vertical structures reflect wave energy rather than absorb it, thereby worsening turbulence and increasing erosion in front of, under and adjacent to the "fix".

The effects of turbulence and erosion are not as severe when rip rap is used because it absorbs some of the energy from moving water. However, depending on its size and placement, rip rap still can create a barrier to many wildlife species, and, as with solid structures, reduces vegetated habitat.

The adverse effects of traditional shoreline stabilization methods can be significant, as hard erosion-control solutions do not provide the water quality or habitat benefits of a natural or restored vegetated shoreline.

2.

New ecology research reports that different ski slope construction methods can greatly impact mountainside ecology. Grading removes more vegetation than clearing and makes the soil less conducive for plant growth, which results in more erosion.

Conclusion

Is artificial stabilization and development really working?

Methods such as seawalls do actually help to protect shorelines from being flooded by strong waves, but if the wave bounces off the wall, there will.be more erosion.

Developers continue to attempt to protect our terrain but it is most likely not helping as much as they hoped it would.
