Answer:
OCEAN LITTER
Litter in the world’s oceans comes from many sources, including containers that fall off ships during storms, trash that washes off city streets into rivers that lead into the sea, and waste from landfills that blows into streams or directly into the ocean. Once in the ocean, this debris may degrade slowly and persist for years, traveling the currents, accumulating in large patches and washing up on beaches.
PESTICIDES AND FERTILIZERS
Use of pesticides and fertilizers on farms has increased by 26-fold over the past 50 years, fueling increases in crop production globally. But there have been serious environmental consequences. Indiscriminate pesticide and fertilizer application may pollute nearby land and water, and chemicals may wash into nearby streams, waterways and groundwater when it rains. Pesticides can kill non-target organisms, including beneficial insects, soil bacteria and fish. Fertilizers are not directly toxic, but their presence can alter the nutrient system in freshwater and marine areas. This alteration can result in an explosive growth of algae due to excess nutrients. As a result, the water is depleted of dissolved oxygen, and fish and other aquatic life may be killed
AIR POLLUTION
Air pollution brings to mind visions of smokestacks billowing black clouds into the sky, but this pollution comes in many forms. The burning of fossil fuels, in both energy plants and vehicles, releases massive amounts of carbon dioxide into the atmosphere, causing climate change. Industrial processes also emit particulate matter, such as sulfur dioxide, carbon monoxide and other noxious gases. Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease. Long-term exposures also can lead to significant climatic changes that can have far reaching negative impacts on food, water and ecosystems.
NOISE AND LIGHT POLLUTION
Artificial light and noise often drown out natural landscapes. In the Arctic, the sounds of oil and gas explorations are so loud that belugas, bowhead whales and other sea life have had difficulty feeding and breeding. Light pollution disrupts circadian rhythms for both humans and animals alike and may even contribute to the development of cancer. Light pollution also can impact sea turtles. Adult and hatchling sea turtles are drawn toward lights along the beach, thinking they are heading toward the moon. Coastal developments, therefore, are encouraged to turn off their lights or cover them at night

The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle. What is a result of preventing spindle fibers from forming? Answer
A The cell cycle skips G1 phase
B Mitotic division is skipped, and the cell cycle proceeds to cytokinesis.
C Mitotic division stops in metaphase and cannot proceed to anaphase.
D The cell cycle skips S phase and proceeds to G2 phase.
Answer: the correct answer is C
Explanation:
Preventing the formation of spindle fibers makes the mitotic division stop in metaphase, and thus fail to proceed to anaphase.
• Colchicine prevents the polymerization of the microtubule, and thus, prevents the arrangement of the mitotic spindle, which shows the prevalence of another checkpoint in the cell cycle.
• As a result, the activity of the maturation promoting factor remains high, the chromosomes stay condensed, and the nuclear envelope fails to redevelop.
• A toxic effect is exerted on the living cells by the colchicine, which usually results in the arrest of the process of mitosis at an eventual stage, generally the metaphase, with the generation of unusual and bizarre nuclear configurations, and thus, resulting in the death of the cell.
Thus, the correct answer is option C.

What can a person do to prevent barriers to exercise? Select three options.
Answer:
Explanation:
Three things that anyone can do to prevent this would be
understand myths about working out
look for inexpensive classes in the area
take a physical education course at school
Most barriers to exercise revolve around becoming discouraged/depressed about the results due to having unrealistic and high expectations. Learning about what you can expect realistically from a set routine will greatly increase motivation and prevent such barriers. The same applies to learning which routines and diets work best and all of this can be learned by taking physical education courses or classes near you.
Answer:
understand myths about working out
look for inexpensive classes in the area
take a physical education course at school
Explanation:

What do surface current affect !!!!
Answer:
Surface currents affect climate by moving cold and warm water around the globe. In general, currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. A surface current warms or cools the air above it, influencing the climate of the land near the coast.

Which graphic organizer best represents asexual reproduction? Which graphic organizer best represents sexual reproduction? Explain your answers.
The one with one parent and five offspring represents asexual reproduction. Asexual reproduction only requires one parent, so the offspring are genetically identical to the parent. The advantage is that organisms can reproduce much quicker using this method.
The organizer with two parents and one offspring represents sexual reproduction. Again, sexual reproduction requires two parents.
What would happen to the geosphere if there was no hydrosphere? Think of weathering and erosion
Answer:
Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of air temperature between the land and oceans). This rock cutting shows the rocks that have formed on the surface of the Earth. Last of all, without the geosphere, there would be no world to live on!

Answer:
bacteria is the pathogen
Answer:
Virus
Explanation:
A virus is the smallest pathogen and can spread easily.
True or false. Without wind there would be no weather.
Answer: Absent a gentle breeze or mighty gale to circulate both warm and cold weather around the Earth, the planet would become a land of extremes. Areas around the Equator would become intensely hot and the poles would freeze solid. Whole ecosystems would change, and some would completely disappear.

Select ALL the correct descriptions that help to define luminosity.
A. How much energy is emitted per second
B. How much surface area the object has
C. The amount of brightness of an object
D. The color emitted by the start
The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

1.What is a plate boundary?
2.What are three interactions can plates have? these are the three major types of plate boundaries.
3. In general what does the theory of plate tectonics explain?
Answer:
1. Plate boundaries are the edges where two of the Earth's plates meet
2. The three types of plate interacts include divergent boundaries, convergent boundaries, and transform boundaries.
3. This is the theory that the Earth's crust is separated into plates that move over the Earth's mantle. As stated, they can move in ways such as coming together, spreading apart, and interacting at boundaries all over the planet, which can cause things such as volcanos and earthquakes. Scientists created this theory as a way to explain why certain events like these are caused.
