desplazaste?
Answer:
5 metros.
Explicación:
Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

What are the causes of variations ? please explain thi also
Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.What data provides the strongest evidence (most valid) that early Earth conditions provided what was necessary for life?
A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.
Answer:
A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.
Explanation:
Thanks OP for answering your own question!
The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.
What are genetic comparisons in evolution?Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.
Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!
Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the fossil record in an attempt to discredit the theory. Which statement would be the best counter argument as to why the fossil record can be relied upon to support evolution?
A. The fossil record provides evidence that extinct species only fossilized during certain geological eras.
B. The fossil record provides evidence that extinct species are genetically identical to current species.
C. The fossil record provides evidence of many different types of organisms, since most species fossilize well.
D. The fossil record provides evidence of many transitional organisms that show relationships between species.
Answer:
D. The fossil record provides evidence of many transitional organisms that show relationships between species.
Explanation:
Evolution is the process of changes in characteristics of an organism as time passes. In order for fossil records to support this, there must be some linkage between species to species. Therefore the correct answer is D. The fossil record provides evidence of many transitional organisms that show relationships between species..
Since its inception, the theory of evolution has been the subject of frequent debate, and the fossil record can be relied upon, the fossil record provides evidence of many transitional organisms that show relationships between species, which is in Option D.
What is the significance of the fossil record?The fossil record tells about the ancestors and explains the diversity of life on Earth over thousands or millions of years ago. It is commonly found in sedimentary rock formations and provides information about how organisms lived thousands or millions of years ago.

The earth is __blank__This trend most closely follows trends in the Earth's __blank__ Within the Earth's __blank__the component that is likely most responsible __blank__
Complete question:
Fill in the blanks.
The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).
Answer:
The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.
Explanation:
Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.
The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.
The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.

Explanation:
. Landfill are is a/an: (a) open area (b) high lying open area (c) open area near a river/lake (d) low lying open area
Answer:
d
Explanation:
Landfills are low-lying open areas specifically designed for the dumping of waste materials to be buried later.
Landfills can be for municipal/household wastes, industrial wastes, or for hazardous wastes. They are usually low lying to facilitate their burial after they must have been filled-up and they represent one of the oldest methods of disposing wastes.
Landfills are not just open areas, they are low-lying as opposed to high-lying, and they are not created near rivers or lakes.
The correct option is, therefore, d.
How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.
Explanation:
Which results from the interaction of solar weather on Earth's magnetic field? Select the two correct answers.
A. geomagnetic storms
B. auroras
C. radiation belts
D. solar wind
Answer:
A & C
Explanation:
In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.
The geomagnetic storms and auroras are the results from the interaction of solar weather on Earth's magnetic field. The correct options are A and B.
What are solar weathers?Solar or space weather refers to actions that take place on the Sun's surface.
These reactions usually have different effects on our planet, owing primarily to the Earth's magnetic field, which acts as a shield for the planet.
A geomagnetic storm happens when the solar radiation collides with the Earth's electromagnetic field, causing disruptions in the magnetosphere.
The interaction of loaded solar particles and the land based electromagnetic field produces an aurora, which is a luminescent formation.
The solar wind transports these particles to the terrestrial electromagnetic field, in which they are shown in various colors depending on the type of particle.
Thus, the correct options are A and B.

Inherited traits are described by probabilities. When experimenting on inherited traits, why is it important to have a large sample size?
Tysm! I love you<33
Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response
