Perimeter = 3x. Area = x^2 * sqrt(3)/4. Explanation of area:. You can divide an equilateral triangle into 2 right triangles, each with a common side we will call y.. Area = area of first right triangle + area of second right triangle = (x/2)*y/2 + (x/2)*y/2 = xy/2. Now: y^2 + (x/2)^2 = x^2 so y…
Answer:
Mayor productividad de los cultivos.
Disminución de vertidos químicos en ríos y aguas subterráneas.
Mayor seguridad de los trabajadores.
Disminución del uso de agua, fertilizantes y pesticidas, lo que a su vez reduce los precios de los alimentos.
Explanation:
Answer:
What should be <u>TRUE</u> of the island of <em>Hawaii</em> :
- Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.
- Its species should be more closely related to those of nearer islands than to those of farther islands.
- It should have a rich fossil record of terrestrial organisms.
Explanation:
In cases of <em>geographic isolation</em>, and subsequent speciation, produced by dispersal and colonization phenomena we can find the island of Hawaii. Adaptation to these environments can be the trigger for divergence. The <em>large number of species</em> in this archipelago, more than 500, seems to have emerged through<em> migration</em> and diversification. Many of these are endemic to a nearby island, and the subsequent<em> evolutionary divergence.</em>
The volcanic islands, which have never been in contact with the continent, are especially<u> rich in endemic species; </u>the species that inhabit them are descendants of those who arrived in times past and <u>were able to adapt.</u>
Almost ninety years ago, in the south of the island of Hawaii, they revealed some <u>bones </u>that turned out to be the<u> first bird fossils discovered i</u>n the archipelago. The bones were under a flow of prehistoric lava and on a bed of volcanic ash.
In short, the Island of Hawaii is of great interest to scientists and there are always new developments buried years ago by volcanic activity.
Answer:
planetesimal assembly
Explanation:
The accretion model, also known as planetesimal assembly, is what gives us the perspective for the formation of the astronomical objects via the process of accretion. Some of the astronomical objects that are formed by this process are the galaxies, stars, planets,and moons. The process of accretion represents the accumulation of particles into an object by gravitationally attracting more and more matter, mostly gaseous matter, forming an accretion disk.
