If you looked at heart cells, would you expect to see a lot of mitochondria or only a few? Why?

Nesterboy [21]

Answer:

Function of Mitochondria. Just as a car runs on gasoline, your cells run on ATP. ... It's your heart muscle cells – with about 5,000 mitochondria per cell – that contain far more mitochondria than any other organ in body! That's because the constantly-beating heart works harder than any other organ in your body!

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of

raketka [301]

From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.

---------------------------------------

Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level.

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).

If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.

5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.

1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.

164.5 MJ of this energy is tranferred to the following trophic level.

Name any two substances which are selectively reabsorbed from the tubules of a nephron.

fgiga [73]

Answer:

Two substances which are selectively reabsorbed from the tubules of a nephron are Amino acids and Glucose.

Explanation:

The majority of the vital nutrients (which do not have to be discharged out) are recovered by the bloodstream out from tubule of the nephron all through re - absorption, a key procedure in urine production that primarily takes place in the PCT of the nephron. Proximal tubule includes unique cuboidal epithelial cells having microvilli towards the lumen for completing this. Higher substance reabsorption is a result of this. Because glucose and amino acids seem to be essential to the organism, hence the nephron's tubules reabsorb them. Moreover, sodium, water and other ions like sodium can also be reabsorbed by nephrons. Furthermore nephron tubules are in charge of waste product elimination and nutrient absorption.
