How much energy is transferred to the next level in a food wed?

1 answer:

4 0

Only a fraction of the energy available at one trophic levelis transferred to the next trophic level; the fractions can vary between 1-15%, with an average value of 10%. Typically the numbers and biomass of organisms decreases as one ascends the food chain.

Answer: teleconferencing

Explanation:

Using peer-to-peer collaboration will not work if the members work at many different locations.

While instant messaging may work, it can be hard to have a meeting this way.

Templates do not apply to this situation.

This leaves us with the answer of "teleconferencing" as you can have a meeting with people online, even when they are far apart.

What is relationship among the location of volcanues,earthquake epicenter,and mauntain ranges?

Korolek [52]

Volcanoes, earthquakes and mountain ranges are all results of the tectonic movement of the Earth.
When two plates collide and one does not completely give way and go under the other the crust is pushed up forming mountain ranges.
An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics).
And volcano is created when plates are pushed together or pulled apart.
So, the relationship between volcanoes, earthquakes and mountain ranges is their connection with the tectonic movement of the Earth.

JulsSmile [24]

There is an EE possibility, 2 Ee's and 1 ee. For the earlobes to be not detached, it would have to be ee, as attached earlobes are recessive. and 1 out of 4 options is ee, so 3 out of 4 options would lead to detached earlobes

A drought causes a wildfire which destroys a forest. Which Earth systems interact during this process? (1 point) Select one: a.

Ne4ueva [31]

Answer:

It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest. 

Explanation:

Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc. a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire

Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in a forest would then engulf the whole forest.

patriot [66]

Answer:

Option- D: Is the best choice to choose from the given options.

Now, let us explain the term Cell cycle in a more comprehensive way.

As the cell cycle is controlled at three checkpoints.

The integrity of the DNA is assessed at the G₁ checkpoint.

Proper chromosome duplication is assessed at the G₂ checkpoint.
Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.

Explanation:

The cell cycle is controlled by three internal checkpoints that evaluate the condition of the genetic information.

The G₁ Checkpoint:This stage determines whether all conditions are favorable for cell division to proceed. The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into G₀ (inactive) phase and await further signals when conditions improve.
The G₂ Checkpoint: The most important role of the G₂ checkpoint is to ensure that all of the chromosomes have been accurately replicated without mistakes or damage.
The M Checkpoint:It occurs near the end of the meta-phase stage of mitosis. it determines whether all the sister chromatids are correctly attached to the spindle micro-tubules
