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°

Which best describes the lower body structures of humans and chimpanzees?

The big toes of humans and chimpanzees are enlarged.
The human foot has three arches, but the chimpanzee foot only has one.
Human knees are very mobile, but chimpanzee knees are stabilized by tendons.
The blades of the human pelvis are not rotated inward like those of the chimpanzee.

Answers

Answer:

B. The human foot has three arches, but the chimpanzee foot only has one.

Explanation:

On edge finished the quiz

The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.

What is the difference between humans and chimpanzees?

Humans have a significantly more developed brain, better motor control, and less body hair. The human brain's neural network has been found to be much more complex, and spindle neurons have also been discovered.

Nucleotide-for-nucleotide was discovered to differ from the human genome with which it was compared by roughly 1.23 percent. This equates to roughly 40 million changes in our DNA, with half most likely the result of mutations in the human ancestral line and the other half occurring in the chimpanzee line since the two species split.

The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.

In this case, we have a large population of lizards that live on an island. These particular lizards can either have an all-green tail or a tail with a black tip. In the large population there are many of each type, but one day, two green-tailed lizards and three lizards with black-tipped tails were picked up by a sailor and dropped off on an island that had no lizards of this kind. It was noted that the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators. The lizards began to breed and eventually produced their own large population after a few years. Make a prediction about what you might find if you visited this island after several years based on what you have learned.

PLEASE HELP!!!

Answers

This is a complicated question that's a little easier if you break it down!

Island One:

- Lizard tails are all green or black tipped.

- This island has many of each type.

Sailors Moved:

- two green-tailed lizards

- three black-tipped lizards

On Island Two, we know that the black-tipped lizards are more likely to survive since the question tells us that "the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators".

The green tailed lizards do not have this advantage, and the predators are eating more of them because of this (especially if there are a lot of predators!).

We also know that the lizards on the island were able to reproduce and form a large popuation- not all of them were eaten by predators.

Based on this information we can predict:

There are going to be a lot more black tipped lizards (or they may all be black tipped lizards) because they have an advantage in surviving longer.

In the 1950s, Stanley Miller performed experiments to study the origins of life. He created an atmosphere rich in methane, hydrogen, ammonia, water, and simulated lightning. Which substances were most likely produced during Miller’s experiments?


A. protists


B. bacteria


C. amino acids


D. RNA strands

Answers

Answer:

c. amino acids

Explanation:

The substances most likely produced during Miller's experiments would be amino acids.

In their simulation of the early atmosphere, Stanley Miller was able to obtain a mixture of organic compounds in the broth with the major one being amino acids.

The discovery of Stanley Miller gave further credence to the chemosynthetic theory of the origin of life because amino acids form the building blocks of proteins and proteins are essential for the onset of life.

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?

Answers

Answer:

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?

Explanation:

The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.

What are the layers of atmospheres?

There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.

Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.

In recent years, scientists and the public have raised a number of ethical and legal questions about DNA. Many of the questions involve issues of ownership and privacy of personal genetic information. Issues like these became relevant to society because which of these scientific achievements?

Answers

ANSWER: The completion of the Human Genome Project

EXPLANATION:

Human Genome Project (HGP) was completed in April, 2003. Genome varies from one individual to another.

The project involved mapping and sequencing of some people and in other to get each chromosome full sequence in individuals.

However, at the beginning of this project, concerns like ownership and privacy of personal genetic information began to spring up. People are afraid that employers may have access to their genetic information and would reject persons with health issues indicated by their unique genes and health insurance companies may also not provide insurance to people that have deficiency.

In the view of this concern, the United States in 1996 passed the Health Insurance Portability and Accountability Act (HIPAA) which guides against the non-consensual and unauthorized release of health information of individuals.

Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli allow oxygen to enter the blood through the capillary beds as pictured above. Alveoli provide much more surface area for the lungs to contact the capillary beds. What is the advantage of lungs with alveoli compared to lungs without alveoli?

Answers

Answer:

It provides more surface area for the absorption of oxygen.

Explanation:

The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.
