how would you compare the magnetic field generated by a simple length of wire to a magnetic field generated by a coil length of wire?

Answers

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.

Define the four major types of symbiosis?

Answers

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.

A group of scientists discovered a new organism with the following characteristics:  Eukaryotic  Nonvascular Reproduces by spores Heterotrophic Cell walls contain chitin. Based on these characteristics, in what kingdom should this new organism be classified?

Animalia
Fungi
Plantae
Protista

Answers

The giveaway here is chitin: that is a component of cell walls unique to fungi. All of the other characteristics listed would also be consistent with those of a fungus.

Thus, the fungi kingdom would be the most appropriate classification.

Based on these characteristics, the new organism should be classified within the FUNGI kingdom.

The Fungi kingdom is composed of multicellular heterotrophic organisms.

It means that fungi need to obtain their food from other organisms.

Fungi can reproduce by different types of spores and their cells have a cell wall.

In conclusion, based on these characteristics, the new organism should be classified within the FUNGI kingdom.

Explain why finding the average energy of the system would be a smarter way to record the temperature than giving the energy of each individual particle

Answers

Answer:

See Explanation

Explanation:

Temperature is defined as the average kinetic energy of the particles of a system.

In a system, there are several particles moving at various velocities and having various values of kinetic energy. It is very difficult to determine the individual kinetic energies of each individual particle.

Hence, we only need to obtain the average kinetic energy of the particles of the system in order to record the temperature.

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.

[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?

Answers

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.

Increased input to this cycle may be responsible for global warming.
carbon

phosphorus

Answers

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.

Why do surface currents move in circular patterns?

Answers

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.

The Coriolis effect causes winds and currents to form circular patterns.

True or False

Answers

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.
