What are examples of pollution that can be caused by agriculture?
A) mercury and cyanide tailings
B) animal waste and pesticide
C) salt and soil sediments
D) gasoline and oil seeping into groundwater

Answers

Yeah it’s definitely B

Examples of pollution that can be caused by agriculture are animal waste and pesticides. The correct option is B.

What is agricultural pollution?

Agriculture can be a significant source of pollution, particularly from the use of chemicals such as fertilizers and pesticides, and the disposal of animal waste.

Animal waste can pollute waterways with excess nutrients, such as nitrogen and phosphorus, which can lead to harmful algal blooms and oxygen depletion in aquatic ecosystems. Additionally, animal waste can contain pathogens and bacteria that can contaminate water sources and pose a risk to public health.

Pesticides can also contaminate waterways and soil, which can have negative impacts on ecosystems and human health. Pesticide residues can accumulate in crops and animal products, leading to long-term exposure in humans and animals.

Other examples of agricultural pollution include soil erosion, which can lead to the deposition of sediments in waterways, and the use of excessive salt in irrigation practices, which can lead to soil salinization and reduce crop productivity.

Therefore, Animal waste and pesticides are examples of pollution that can be caused by agriculture.

the purpose of a nuclear power plant is to transform nuclear energy to electricity. this is done in steps starting with a nuclear reaction which generates heat to produce steam. the steam in turn is used to turn a generator which finally produces electricity. which answer best illustrates these energy transformation.

A. nuclear --> mechanical --> chemical --> electrical
B. thermal --> nuclear --> mechanical --> electrical
C. mechanical --> thermal --> nuclear ->electrical
D. nuclear --> thermal --> mechanical --> electrical

Answers

it's D, nuclear to thermal to mechanical to electrical

Energy order is nuclear --> thermal --> mechanical --> electrical.

What is  thermal energy?

The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process.

Mechanical energy, also known as kinetic energy or potential energy, is the energy that an object possesses when it is in motion or the energy that an object stores due to its position. Renewable energy is also fueled by mechanical energy.

15. Astronomers use different types of telescopes to observe different parts of the
electromagnetic spectrum. This allows astronomers to study objects in space. Some
electromagnetic waves are blocked by Earth's atmosphere, making it difficult for
astronomers to focus the energy into a viewable image. Instead of actually viewing
the energy, astronomers have learned to view the interactions of the energy with
the atmosphere. These faint interactions with the atmosphere allow them to study
highly energetic objects such as pulsars and black holes.

What is an electromagnetic spectrum?

The complete range of electromagnetic radiation, classified by frequency or wavelength. Despite the fact that all electromagnetic waves have a wide range of frequencies, wavelengths, and photon energies, they all move at the speed of light in a vacuum.

The range of all electromagnetic radiation is represented by the electromagnetic spectrum, which also includes numerous subranges, also known as portions, such as visible light and ultraviolet radiation.

The various parts have different names based on variations in the emission, transmission, and absorption of the corresponding waves as well as on the various practical uses for which they are put to use.

Use the information and model to answer the following question.



Echippus is an early ancestor to modern horses that lived 40 million years ago. The organism had a short neck, a short tail and feet with four toes. After ten million years, the tail and neck became longer and one of the toes disappeared as evidenced by the fossil of Mesohippus. Evolution of these organisms continued for 20 million years up to the present day causing the organisms to have longer necks and one solid hoof.

Answers

Answer:

D

Explanation:

The fossil record shows that the mammals gradually evolved so that their toes became one large hoof so this variation must have been more useful for survival than many toes. The correct option is 1.

What is fossil record?

Paleontologists, archaeologists, and geologists use the fossil record to place important events and species in the correct geologic era.

It is based on the Law of Superposition, which states that the bottom layers in undisturbed rock sequences are older than the top layers.

The neck and toes of early horse ancestors evolved in such a way that the neck and tail became longer and one of the toes disappeared over time. The fossil record demonstrates this, as Echippus had a short neck, a short tail, and four-toed feet.

The fossil record shows that mammals gradually evolved their toes into one large hoof, implying that this variation was more useful for survival than many toes.

Thus, the correct option is 1.

Objects that are denser than water will sink in water. Question 1 options: True False

Answers

Answer: True

For example, a very dense metal will sink to the bottom while something like wood will float on the surface. The wood is less dense compared to the water, which is why it floats. Density is the measure of how much stuff you can pack in a certain volume. The higher the density, the more stuff per volume. Think of it like packing a suitcase. If there's barely anything in there, then we can say its density is low. The more stuff crammed in the suitcase will increase the density (and therefore the weight), while keeping the volume the same.
