¿Cómo puede el río cambiar el lugar de la topografía?
Answer:
Los mapas topográficos utilizan el sistema de representación de planos acotados, mostrando la elevación del terreno utilizando líneas que conectan los puntos con la misma cota respecto de un plano de referencia, denominadas curvas de nivel, en cuyo caso se dice que el mapa es hipsográfico.
Explanation:Además de los campos mencionados anteriormente, la topografía es fácilmente aplicable a cualquier trabajo o proyecto donde se necesite realizar planos, obtener datos de un terreno y ubicar puntos en la superficie terrestre con gran precisión y rigurosidad técnica.Es posible determinar la posición de un punto sobre un plano horizontal: a partir de un solo punto conocido, por levantamiento de poligonales , un método que consiste en medir distancias horizontales y azimut a lo largo de una línea quebrada (ver Sección 71);

What can happen when a community becomes isolated from the rest of its species for many generations?
a) Competition between individuals will decrease.
b)The community will grow more slowly.
c)A new species can form.
d)There would be no effect on the community.
Answer:
C) A new species can form.
Explanation:
This is the concept of genetic drift, where a species being isolated gets an unnatural change in the gene pool, and thus can evolve differently.
Which two statements below correctly describe one similarity and one difference between cellular respiration and photosynthesis?
Cellular respiration and photosynthesis both involve water.
Cellular respiration uses sugar and photosynthesis produces sugar.
Cellular respiration and photosynthesis both use light to produce energy.
Cellular respiration requires light energy and photosynthesis requires chemical energy.
A. Statements 1 and 2
B. Statements 1 and 4
C. Statements 2 and 3
D. Statements 3 and 4
Answer:
The answer is A.
In the equation of breakdown of glucose (cellular respiration) and photosynthesis the end product of both is water, oxygen and carbon (iv) dioxide. And both involve glucose in the chemical reaction.

Match the structure with the correct type. A structure type may be used more than once. 35.bat wing and mouse arm_____A. homologous structure 36.reptile foot and bird foot ____B. analogous structure 37.dolphin fin and fish tail ____C. vestigial structure 38.eves on a blind cave fish ____ 39.snake tongue and dog nose ____
Answer:
35. A. homologous structure
36. B. analogous structure
37. B. analogous structure
38. C. vestigial structure
39. B. analogous structure
Explanation:
A homologous structure is a similar structure/trait found in different species because they diverged (evolved) from a common ancestor, i.e., these species share a common ancestor that had the homologous structure/trait. A homologous structure may have the same or different functions in the descendants. Conversely, an analogous structure is a similar structure/trait that evolved independently (i.e., by convergent evolution) in different species to have the same function, thereby these species don't share a common ancestor with the trait. Finally, a vestigial structure is a rudimentary biological structure found in an organism that has lost its original/ancestral function (e.g., the appendix in humans or the hindlimbs of the snake). Vestigial structures provide strong evidence for evolution by use/disuse of body parts.
Homologous and Analogous structures differentiate in origin and function. Vestigial structures have lost their function. A) Homologous, B) analogous, C) analogous, D) vestigial, E) analogous.
What is an homologous structure?Homologous characters are the structures of different organisms that,
are composed of the same basic elements. share the same position in the body and the same relationship with adjacent structures.share the same embryological development.These structures might express some variations between the organisms that might be related to their function and to the environment. Their function is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
What is an analogous structure?Analogous structures are those body parts of different organisms that accomplish the same function, but they are originated from different areas. These structures do not share the same origin.
What is a vestigial structure?Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.
Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.
According to these definitions, we can answer the questions.

Which weather event usually includes heavy precipitation, strong circulating winds, develops over water, and has warmer surface air temperatures?
Answer:hurricane tropical cyclone
Explanation:
A hurricane is a large rotating storm with high speed winds that forms over warm waters in tropical areas. Hurricanes have sustained winds of at least 74 miles per hour and an area of low air pressure in the center called the eye
As part of the greenhouse effect, Earth’s surface radiates heat back into the atmosphere and the atmosphere absorbs this heat. Why do areas near the equator generally radiate more energy back into the atmosphere than areas near the poles?
Areas near the equator have more clouds in the atmosphere than areas near the poles.
Areas near the equator receive more incoming solar energy than areas near the poles.
The greenhouse effect only occurs near the equator.
The greenhouse effect only occurs near the poles.
Answer:
The correct answer is B. Areas near the equator receive more incoming solar energy than areas near the poles.
Explanation:
The equator is located in the center of the planet from North to South, this location cause this zone and nearby zones to receiver more solar energy than areas near the poles. This occurs because the natural tilt of Earth makes sun rays directly hit the equator all the time of the year, while areas in the poles are not hit directly and the exposition to sunlight varies with the seasons of the years. This explains why in the equator the temperatures are higher than in the poles. Besides this, the difference in radiation received makes areas in the equator radiate more energy back due to global warming gases, and the global warming phenomenon.
Areas near the equator receive more incoming solar energy than areas near the poles.

The features of alveoli for the efficient exchange of gases.
A. Thin wall, moist layer and less blood vessels
B Thin wall, moist layer and more blood vessels
C. Thick wall, moist layer and more blood vessels
Explanation:
The alveoli are lined with mucus and are surrounded by a network of blood capillaries. They have very thin walls for gases to be absorbed through. An individual air sac is called an alveolus. The layer of moisture in the alveoli allows gases to dissolve so that they can diffuse quickly.
