Which function is performed by Earth's magnetic field?
mafiozo [28]

Answer:

D. Ultraviolet rays from the sun are prevented from reaching Earth.

surface.

Explanation:

What little is known is that the Earth's magnetic field creates the so-called "magnetic shield" that provides protection against some other dangerous forms of radiation, namely cosmic rays and solar wind.

While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.

Flura [38]

Answer:

The answer is C. The cell took in another ancient prokaryotic cell, which began living inside it.

Explanation:

  • The Endosymbiont Theory explains the evolution of membrane bound organelles such as mitochondria and chloroplasts.
  • According to the theory, mitochondria evolved when an ameoba like organism engulfed bacteria capable of cellular respiration.
  • Similarly, chloroplasts were developed when the ameoba like organism engulfed cyanobacteria or blue-green algae capable of photosynthesis.
  • These organisms survived inside the ameoba over millions of years to develop into mitochondria and chloroplasts.
  • The fact that mitochondria and chloroplasts have their own circular DNA and ribosomes is evidence of the endosymbiont theory.

Ber [7]

Answer:

Solar energy    

Explanation:

There are different kinds of energy, and one of them is radiation. By concept, radiation refers to the emission, propagation, and transference of energy in the form of electromagnetic waves or particles.  Living beings depend on solar energy from their origins.  

Throughout the trophic web, there exists a process of energy transference through the different trophic levels, in which every organism feeds on the preceding one and becomes food for the next one. Producers take solar energy and transform it into chemical energy, which is the one from one level to the other.  

<u>Energy flow</u>: From the whole quantity of solar energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.    

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.  

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels (4 or 5).

Climate has changed over geologic time. How does this map provide evidence to support this claim?
DedPeter [7]

Large sources of fossil fuels are found in cold regions shows evidence of climate change.

<h3>What this map shows?</h3>

This map shows that large sources of fossil fuels are found in cold regions because fossil fuels are extracted from the living organisms body so in cold regions once there was a large number of organisms lived there. When they died the fossil fuel sources are formed.

So we can conclude that large sources of fossil fuels are found in cold regions shows evidence of climate change.
