Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.
Define the four major types of symbiosis?
Answer:
There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition. To explore these relationships, let's consider a natural ecosystem such as the ocean. Oceanic environments are known for their species diversity
Explanation:
Answer:
Mutualism - An interaction between two organisms in which both organisms benefit from.
Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.
Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm to the host
Mimicry - imitation of another organism for survival
Explanation:
First lets define symbiosis
Symbiosis : Interaction between two organisms predominantly to benefit one or both of the organism
Now lets find the 4 types of symbiosis
The four major symbiotic relationships include mutualism, commensalism, mimicry and parasitism
Now lets describe/define each symbiotic relationship
Mutualism - An interaction between two organisms in which both organisms benefit from.
An example would be sharks and remora fish. Remora fish keep the water fairly clear of scraps around the shark which prevents the development of unhealthy organisms resulting in a healthy shark. In return remoras receives a fairly convenient food source and they receive protection.
Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.
An example would be frogs and plants. Frogs use plants for protection and the plants way of life does not change in any way
Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm
An example would be fleas and dogs. Fleas live off of the blood in the organism (the dog in this case). Consequently the dog experiences hair loss, scratching, and irritated skin.

Because of rising ocean temperature, the Great Barrier Reef off the coast of Australia is experiencing coral bleaching, which kills resources such as plants and fish populations. This ultimately leads to tremendous .
Answer:
The correct answers are:
1. stratospheric ozone depletion
2. climate change
3. desertification/land degradation
4. freshwater decline
5. biodiversity loss.
Explanation:
1) Stratospheric ozone depletion- ozone layer is the protective layer around the earth that protects us from harmful rays such as UV rays coming from the sun. There are depletions or holes in the ozone layer in some parts of Australia and therefore, therefore leading to skin cancer.
2) climatic change - The change in the average temperature or precipitation of an area that takes place due to global warming that changes the earth's climate is changing rapidly.
3) desertification or land degradation - It occurs due to past overuse of fertilizer or barren land that has zero crop yield.
4 )freshwater decline - freshwater is an essential part of the irrigation of crops in agriculture and due to the downfall of groundwater its decline the freshwater produce in these parts.
5) biodiversity loss - Coral reefs are habitats for many aquatic organisms and used as various ways of biodiversity. If there is a loss or decrease in their numbers it will affect and decline the biodiversity of the area.

Increased input to this cycle may be responsible for global warming.
carbon
potassium
nitrogen
phosphorus
Answer:
Carbon
Explanation:
Global warming is currently a great concern to the world. It is the process whereby the temperature of the atmosphere rises due to the effect of certain gases called GREENHOUSE GASES. Greenhouse gases are those gases that have the ability to trap and emit heat into the atmosphere e.g carbon dioxide, methane, CFC etc.
Carbon dioxide and methane, for example, are greenhouse gases that contain CARBON element in their structure. This implies that an increased input to the CARBON cycle may be responsible for global warming because more carbon input produces more carbon-based greenhouse gases, utterly leading to global warming.

Answer:
Industrial waste (toxic chemicals)Sewage (contains harmful bacteria)Oil spills from boatsAgriculture (pesticides and animal waste)Radioactive waste from nuclear powerplantsDumping trash (trash such as plastics, glass, styrofoam, etc.)Acid rain (caused by the burning of fossil fuels)Mining activities (particles from mining)Soil erosion due to deforestationLeakage from landfillshow would you compare the magnetic field generated by a simple length of wire to a magnetic field generated by a coil length of wire?
Answer:
The coil generates a stronger magnetic field. The coil generates a weaker magnetic field. The field generated by the coil has a different polarity than the field generated by the length of wire.
Explanation: Good Luck!!
Answer:
The amount of magnetic field generated by the wire can be calculated if you know the length of wire and current. ... You can add more coils on top of the first row, and this just adds more field strength. In technical terms, every coil of wire increases the "magnetic flux density" (strength) of your magnet.
The coil generates a stronger magnetic field. The coil generates a weaker magnetic field. The field generated by the coil has a different polarity than the field generated by the length of wire.

Toxic substances are also classified by how people are exposed to them. By definition, people may be exposed intentionally, accidentally, or deliberately.
True or False
Answer:
The statement is true.
Explanation:
When a chemical substance is dangerous for people's health, we speak of a toxic risk. This risk can materialize if exposure to the chemical agent is not controlled. Toxic substances are those substances capable of causing harmful effects in a living organism when they come into contact with it or when ingested, intentionally, accidentally, or deliberately. The toxic risk of a chemical product depends on two factors: the toxicity and the absorbed dose, where a series of factors influence: composition, properties, concentration, duration of exposure, route of entry into the organism and workload.

- A 47-year-old male presents to the emergency department complaining of malaise, fever,
and painful nodules on the pads of his fingers. He admits to being an active IV drug abuser,
while denying regular medical and dental care. Upon physical examination, the nurse notes a
soft systolic murmur and small painful nodules on the pads of his fingers. Based upon these
physical examination findings, the physician thinks that the patient may have infective
endocarditis and prescribes antibiotics.
a. What should the nurse ensure happens before the antibiotics are
given?
Answer:
To be sure about the cause of the pain.
Explanation:
The nurse must ensures the presence of bacteria or microbes before the antibiotics are given because the antibiotic is used for the killing of these microbes such as bacteria. endocarditis happens when the bacteria or fungi enters to the heart through blood streams and cause problems there so for removing this infection we must use antibiotic that kills this microorganisms so the nurse has to make sure that the symptoms is due to microbes or not before the use of antibiotic to avoid any consequences.

Why do surface currents move in circular patterns?
Answer:
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
Surface currents are created by three things:
global wind patterns
the rotation of the Earth
the shape of the ocean basins
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Answer:
The Coriolis effect causes winds and currents to form circular patterns.

[Please help me with this question and please explain WHY you chose what you chose] The diagram shows a plant and an animal cell. Which is most likely true about both cells?
Both plant and animal cells use the same molecules for energy for the production of ATP (adenosine triphosphate) and glucose. Therefore, the correct statement is option B.
What is ATP?ATP is the energy currency of the cell and provides energy required for many cellular processes, such as muscle contraction, protein synthesis, etc. Both plant and animal cells produce ATP through cellular respiration, where glucose is breakdown to release energy in the form of ATP.
Glucose is a simple sugar serving as a source of energy for both plant and animal cells obtained from breakdown of complex carbohydrates in plant cells and animal cells.
However, plants can also produce energy through photosynthesis by converting light energy into chemical energy in the form of glucose. During photosynthesis, plant cells use sunlight to convert carbon dioxide and water into glucose and oxygen.
Therefore, both plant and animal cells use the same molecules for energy, primarily ATP and glucose.
