Answer:
The coral reefs of the Caribbean are thought to be under threat
Explanation:
Overfishing threatens over 60 percent of Caribbean coral reefs. Declines in coral cover and increases in algal cover have been observed across the region. This analysis identified about one-third of Caribbean reefs at high threat from overfishing pressure and about 30 percent at medium threat.

Which of the following describes erosion caused by glaciers?
It forms big ice chunks.
It changes the temperature.
It happens quickly.
It takes a long time.
Answer:
The 4th option.
Explanation:
Erosion from glaciers takes a long time because glaciers move very slowly across the land. For example, The Appalachian Mountains in the U.S. used to be really tall but slowly overtime, glaciers rounded them off.

What would a graph of carbon dioxide absorption look like for this forested
area?
A. A line that goes up and down
B. An increasing line
C. A decreasing line
D. A flat line
Answer:
A decreasing line
Explanation:
The graph of carbon dioxide absorption look like a decreasing line for the forested area. Thus, the correct option will be C.
What is Carbon dioxide absorption?The absorption of carbon dioxide gas is an important process in many of the practical applications such as the reduction of greenhouse gases, separation as well as the purification processes in the chemical and the petroleum industries, and it also involve capturing of the radioactive isotopes in the nuclear fuel cycle and environment.
The carbon dioxide gas is captured and it can be put to the productive use in enhanced oil recovery as well as the manufacture of fossil fuels, building materials, and more, or it can be stored in the underground geologic formations in the environment.
Therefore, the correct option will be C.

Answer:
invasive species
Explanation:
they ruin the natural habitat and are therefor invasive
A species which is carried into a new location by people is called an invasive species. An invasive species can damage the food chain of an ecosystem.
What is an invasive species?An invasive species is an introduced species which becomes overpopulated and harms the environment into which it is introduced. Although most of the introduced species are neutral or beneficial with respect to other species, an invasive species adversely affect habitats and bioregions, which causes ecological, environmental, and economic damage.
Some of the examples of invasive species are Zebra mussels are native to the Black Sea and the Caspian Sea in Central Asia. Zebra mussels arrived in the Great Lakes of North America accidentally.

Which activity causes the least amount of wetland and estuary degradation when it occurs near the coast?
A. dune grass rehabilitation
B. hydrologic alterations
C. agricultural development
D. urbanization and land development
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

A student noticed that when a dog is cut, the dog periodically licks its wounds. Usually
after a few days, the wound begins to heal without ever showing
signs of infection. The
following steps outline the student's line of reasoning:
1. I wonder why the dog's wound doesn't become infected.
2. The dog's saliva must prevent the growth of infection-causing bacteria.
3. I'll obtain a bacterial culture and grow the same kind of bacteria in two identical
culture dishes. Once the bacteria start growing, I'll add dog saliva to only one of the
dishes and leave the other alone. I'll cover both dishes. Then I'll observe what
happens each day for a week.
4. Even after adding the dog saliva to one of the dishes, the bacteria continued to grow
in both dishes over the course of the week. However, the bacteria in the treated dish
grew more slowly than the bacteria in the untreated dish.
5. I think I'll try something else. I'll start with two identical culture dishes, as before, and
use the same kind of bacteria in each dish, but this time I'll treat one dish with dog
saliva before I add the bacteria. I'll observe what happens each day for a week. 12.
For the dog scenario above, what is the control

Answer:
Frogs go brrrrr
Explanation:
If a brown toad is in a forest then it will be harder to spot. If a bright yellow-green colored frog were in the same forest, it would be much easier to spot. So their appearence helps them survive by being harder to spot and allowing them to live and avoid preadators.

Which biomolecule provides cells with the most energy per gram?
lipids
proteins
nucleic acids
carbohydrates
Answer:
carbohydrates
Explanation:
Among the choices above, it is "carbohydrates" that provide the most energy per gram. Although both carbohydrates and proteins provide 4 calories per gram, carbohydrates contain the most number of glucose, which is being used in order for the body to have energy. So, if you want a quick way to become energetic, it is best to eat "healthy carbohydrates" than proteins.
Around 60% of proteins are converted into glucose while 100% of carbohydrates are converted into glucose. Therefore, carbohydrates provides more energy.

If you are building a dichotomous key and you have 10 species to identify, how many couplets should your key have?
A) 04
B) 05
C) O9
D) 10
Answer:
10
Explanation:
easch couplet presents the user with 2 alternatives and exclusive sets of character's.
10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.
What is dichotomous key?A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.
A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.
The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.
