A fire sits 72 feet from the abs of 125 foot tall building. Find the angle of Evel at ion from the fire to the top of the building
Answers
Answer:
60°
Explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°

Moving a book to a lower shelf decreases potential energy.
True
False
Answers
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

A. as you move down the structure, the groups become more general
B. there are more organisms in each group as you move down the structure
C. as you move up the structure the group becomes more specific
D. as you move down the structure, there are fewer organisms in each group
Answers
Answer:
D. as you move down the structure, there are fewer organisms in each group.
Explanation:
When we move down from kingdom to species, the number of organisms decreases because more closely related organisms are placed down the group. There are fewer kingdoms that have a large number of organisms in it and has less similarities among them and when we move down, the number of organism decreases in number and at the end there are few organisms are present in it which is more closely related to each other.
Matt use a camera to take a picture of a rose on a piece of paper in the picture the rose appear to be bright red and the background appear to be white then Matt place a blue glass filter over the camera lens and took another picture in this picture of the Rose appear to be black in the background appear to be blue explain what happens to light waves to make the appearance of the rules in the appearance of the background different in the two pictures.
Answers
The blue glass filter absorbed most of the red light waves and allowed only the blue light waves to pass through, resulting in the appearance of the rose and the background being different in the two pictures.
What is Light?
Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in straight lines and has both wave-like and particle-like properties. Light is a fundamental part of our world and plays a crucial role in our lives.
Light is produced by the motion of charged particles, such as electrons, and can be emitted by sources such as the sun, light bulbs, and fires. Light travels at a constant speed of approximately 299,792,458 meters per second in a vacuum, which is known as the speed of light.
When Matt took the first picture of the rose on a piece of paper without any filter, the camera captured the visible light waves that were reflected by the rose and the background. The rose appeared bright red because it reflects mostly red light waves and absorbs other colors, and the background appeared white because it reflects all the visible light waves equally.

anaerobic, heterotrophic bacteria
Answers
Answer:
Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.
Autotrophic can be called producers, and heterotrophic can be called consumers.
The question states that "did not use oxygen for respiration and were unable to make their own food"
Only one option satisfies the question:

What are Single-celled organisms?A unicellular organism is also known as a single-celled organism. It is an organism which consists of a single cell, unlike a multicellular organism that consists of multiple eukaryotic cells. Organisms fall into two major categories including prokaryotic organisms and eukaryotic organisms.
All of the life forms can be divided into three major domains, based on the type of cells of the organism into
a. Bacteria: These cells do not contain a nucleus.
b. Archaea: These organisms do not contain a nucleus, however they have a different cell wall from bacteria.
c. Eukarya: These cells contain a well-defined nucleus

Answers
Answer:
Decreased production of energy.
Explanation:
Decrease in bile juices may lead to decreased production of energy from eating of food having fats because our body has no ability to absorb fat-soluble vitamins and fatty acids. Bile juices is responsible for the absorption of fat-soluble vitamins and fatty acids which is then transported to the cell for producing energy that is required by our body for different processes. Fats have more energy than carbohydrates and protein so if there is no bile juices are present so it break down does not occurs.

How did New Zealand's early ecology affect which traits were selected for/against in the kakapo's ancestors?
Answers
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.
Some cells can die as a result of external agents suck as poison or trauma. However, most cells die through a process known as apoptosis, or programmed cell death. What is a likely consequence of a mutation that prevents apoptosis
Answers
Answer: A tumor
Explanation:
A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.
What is apoptosis?A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.
When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.

What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism.
