How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

what kind of fault forms between two plates that are converging?
Answer:
Reverse faults occur at convergent plate boundaries, while normal faults occur at divergent plate boundaries. Earthquakes along strike-slip faults at transform plate boundaries generally do not cause tsunami because there is little or no vertical movement.

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.

1. Compact, complex animals have internal exchange surfaces that are extensively branched or folded, providing a large _____________.
2. In the _____________, nutrients are absorbed across the many fingerlike projections of the lining of the intestine.
3. In the _____________, oxygen and carbon dioxide are exchanged across the epithelial linings of sacs at the tips of tiny air tubes.
4. In the _____________, wastes are removed from the blood across the epithelial linings of excretory tubes.
5. The _____________ transports materials between the exchange surfaces of other organ systems and body cells.
6. Body cells are bathed in _______________, and exchange between body cells and the blood takes place through this fluid.
Answer:
1.) Surface area
2.) Digestive system
3.) Respiratory system
4.) Urinary system
5.) Circulatory system
6.) Interstitial fluid
Explanation:
In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:
--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.
--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.
--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.
--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.
For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood

Why isn't medical and chemical waste placed in landfills ? A. It would contaminate the land and water with dangerous poisons B. It would cause the landfills to fill up too quickly C. It would prevent refuse from breaking down over time D. It would contribute to global climate change
Answer:
A. It would contaminate the land and water with dangerous poisons
Explanation:
Putting medical and chemical waste into landfills has extremely dangerous consequences to the environment and public health.
If they were put into landfills, these toxic wastes would leech into the soil and groundwater below them.
These toxins can accumulate over time, and harm plants and animals.
Humans may also absorb these toxic chemicals.
So, the correct answer is A. It would contaminate the land and water with dangerous poisons
Answer:
A
Explanation:
The water and land will become contaminated which will harm or endanger all the living organisms and us humans around it. Because they use the water and land source.

rashid is conducting a seminar on the importance of coral reefs which point should he include
Answer:
Protect coastlines from storms, erosion and provide habitat.
Explanation:
Coral reefs protect coastlines from storms and erosion as well as provide a habitat for thousands of aquatic animals. These points rashid must include in his seminar. Coral reefs are very important for the marine ecosystem because it can save the soil from erosion and decreases the intensity of storms by acting just like barrier. It provides food as well as living place for many organisms so these point are very important to be included in the seminar.

How is a person exposed to toxins? Explain each. (There are three ways to be exposed to toxic substances.
Answer:
Three ways to be exposed to toxic substances:
1. Inhalation - Inhalation is when we are breathing something into our lungs. For example, a firefighter may ingest toxic gasses and chemicals when entering a burning house.
2. Ingestion - Ingestion is when we are taking something by mouth. If someone eats a piece of cheese that is expired, they will most likely get food poisoning.
3. Skin contact - Skin contact is when a substance is in direct contact with our skin. For example, if someone spills an acidic substance on their arm during science class, this is considered a toxin and they may get a painful chemical burn.
In what year should we expect ocean pH to adversely affect zooplankton population?
The year we should expect ocean pH to adversely affect zooplankton population is 2030.
What are zooplanktons?Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.
