Select the living organisms that will decrease as a result of the loss of coral in the food web.

Answers

Answer:

Butterfly fish, Triggerfish, parrotfish, and sharks

Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?

Answers

Answer:

40% increase

Explanation:

Percentage Increase Formula:

Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%

To Calculate Percentage Increase:

   1) Subtract final value (later value) minus starting value (initial value)

  2) Divide that amount by the absolute value of the starting value (initial value)

  3) Multiply by 100 to get percent increase

Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.

So for your problem,

[(420-300)/300]*100% = 40% increase

which bone layer holds calcium and other minerals

Answers

Answer:

In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

C. long cool summers, short dark winters, migrating animals

D. treeless, permafrost, cold dark winters

Answers

Answer:

D. treeless, permafrost, cold dark winters

Explanation:

The correct answer would be D

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.

What is a tundra?

The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.



Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.

Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.

Therefore, option (D) is correct.

A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.

Answers

Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to  use

When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.

Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).

When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.

In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

[2x + 3y = 1][5x - 4y = 14] Your job as a researcher for a college is going well. You have gained confidence and skill at pulling data and you are not making as many rookie mistakes. The college executives are begging to take notice of your skills. The college has had serious problems with reporting in the past for several reasons. One problem is there was no centralized department for numbers. Human Resources did some reporting, financial aid another, and the rest was covered by the registrars office. It was difficult to determine simple things like number of students enrolled in the fall semester because different departments would generate different. The higher ups want one consistent number they can rely on and they think your department should be in charge of generating that number. As the first report as the official office numbers they want you to generate a report that tracks student demographics over time (a longitudinal study). Your college has a large percentage of its student body who are affiliated with the military (active duty military, retired military, military spouse, military dependent). For this study the college executives want to see how they stack up to other colleges that have a large percentage of military students. After doing some research you find a field in the database that named mil_status. The documentation you have on the field says this is the field you are looking for. Since you need to determine when the student was in the military to generate this report you look for a start and end date associated with mil_status. Sure enough the table also has a mil_status_start and a mil_status_end field. These fields when combined with enrollment data allow you to determine if a student was in the military when they were a student. You query the data to check for bad dates and discover a serious issue. Most of the start dates and end dates are NULL. You once again make some quick phone calls to find out whats going on. It seems this field is not populated unless the college receives official paperwork from the military listing the soldiers enlistment date. In addition to this you find out that students are not required to update their information ever semester. This means once their mil status is set it is unlikely to ever change. Based on this information prepare a post that addresses the following: 1) What recommendation(s) would you make to the colleges executives to address this issue? 2) Collecting this data will have tangible and intangible costs associated with it. For example requiring official paper work adds an extra burden on registration and on the student. Students may decide to go elsewhere instead of supplying the paperwork or may stop identifying themselves as military. The executives want the data but they dont want its collection to impact enrollment or place an undue burden on registration (the line is long enough already). How would you respond to these concerns?3) You noticed something odd in the mil_Status field. The possible values are "Active Duty Military", "Military spouse", "Retired military", "Military Reserves", and "Military dependent". In what way is this field problematic?
