¿Cómo puede el río cambiar el lugar de la topografía?

Answers

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);

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.

Answers

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.

What is greenhouse effect?

Why could reproductive cells from an apple tree and a banana tree never combine to form an offspring? Use data and scientific reasoning to construct an explanation.

Answers

Answer:

Difference in chromosome number.

Explanation:

The reproductive cells from an apple tree and a banana tree never combine to form an offspring because of the difference of species. There is different number of chromosomes in the both apple and banana tree. There are 17 number of chromosomes in apple whereas 33 number of chromosomes in banana tree so due to this difference in the chromosome number apple and banana tree can produce offspring due to combination.

The process of formation of new offspring from the parents is called reproduction. Reproduction help to ensure the continuity of species generation after generation. There are two types of reproduction, these are as follows:-

SexualAsexual.

Reproduction required the gametes of the same species for fusion. The mating of the two gametes is known as fertilization.

According to the question, the apple tree and a banana tree never combine to form offspring because of the gamete difference, These gametes are from different species.

Hence, they cannot reproduce.
