Prokaryotic cells do not contain many of the organelles that eukaryotic cells have. Prokaryotic cells do have a primitive form of Ribosomes.

What are Prokaryotic cells?

Prokaryotic cells may be defined as the types of cells that lack a well-defined nucleus and other membrane-bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA.

A Prokaryotic cell typically has a cell membrane or plasma membrane that functions or operates like a protective cover. Golgi apparatus, mitochondria, and chloroplasts are significantly absent in prokaryotic cells. This is because they are membrane-bound cell organelles.

The traces of ribosomes are required for the process of protein synthesis in order to accomplish metabolic activities required for the survival of prokaryotic organisms.

Therefore, the primitive form of ribosomes is generally present within the prokaryotic cells.

Based on the second law of thermodynamics, how much biomass of phytoplankton would be needed to produce 1 kilogram (kg) of large fish in this food web?

Answers

Answer:

1000kg

Explanation:

The 10% rule states that 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level. So, in a 4 levels food web, we need 1000 kg of the first level -phytoplankton- to produce 1 kg of the last level -large fishes-.

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

From the energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers. This small percentage of this energy flows through all organisms in the ecosystem -from autotrophs to heterotrophs- until it dissipates in the environment.

Only 10% of energy is tranferred from one level to the next one. This assessment is called The 10% rule. It states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.

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

Let us analyze the given example.

Phytoplankton ⇒ Zooplankton ⇒ Small Fishes ⇒ Large Fishes

According to the 10% rule, to support 1 kg of large fish, 10 kg of the anterior level -small fish- is needed.

To get the biomass of each level needed to support 1 kg of large fish, we need to multiply each level biomass by 10. This is:

To get 1 kg of large fish: 1 kg x 10 = 10Kg of small fish To get 10 Kg of small fish: 10 kg x 10 = 100Kg of zooplanktonTo get 100 kg of zooplankton: 100Kg x 10 = 1000 kg of phytoplankton.

So, in this example, to produce 1 Kg of large fishes, we need 10 kg of small fishes, 100 kg of zooplankton, and 1000Kg of phytoplankton.

Redacta un escrito dónde expliques como está formado(un ecosistema), menciona ejemplos y como sigue una estabilidad por el equilibrio entre los factores físicos y biologícos en el ecosistema

Answers

Answer:

Un ecosistema esta formado por facotres abioticos y bioticos.

Los factores bioticos son aquellos que presentan signos vitales, es decir que cumplen con la vida, metabolismo, respiracion, entre otras funciones vivas.

Los factores abietos son aquellos que no tienen vida pero con los que los factores bioticos intercambian energia, un ejemplo de esto son las rocas, los vientos, los sedimentos, la tierra fertil.

Los factores bioticos serian los organismos vivos como los animales, que al funcionar como sistemas abiertos de intercambio de energia constante mantienen un equilibrio fisico biologico con los factores bioticos.

Explanation:

Los ecosistemas cumplen con una cadena que no debe romperse ni faltar ningun eslabon, si esta continuidad se interrumpe con la extincion de una especie como animal o vegetal el ecosistema variará, y cambiara toda su conformacion.

Es un conjunto de factores bioticos y abioticos en armonia que se complementan e intercambian energia entre si de manera ordenada en eslabones, si uno de estos eslabones se rompe, se extingue, o se modifica por intervencion del hombre u otros factores TODO el escosistema se verá modificado o afectado.

Answers

Answer:

true

Explanation:

yea a theory has not tested hypothesis

Answer:

Testing a hypothesis can lead to one of two things: the hypothesis is confirmed or the hypothesis is rejected, meaning it either has to be changed or a new hypothesis has to be created.  This must happen if the experiments repeatedly and clearly show that their hypothesis is wrong.  It doesn’t matter how elegant or supported a theory is—if it can be disproven once, it can’t be considered a law of nature.  Experimentation is the supreme rule in the scientific method, and if an experiment shows that the hypothesis isn’t true, it trumps all previous experiments that supported it.  These experiments sometimes directly test the theory, while other times they test the theory indirectly via logic and math.  The scientific method requires that all theories have to be testable in some way—those that can’t are not considered scientific theories.

In a coal-burning power plant, the coal is an example of a system _____.

Answers

I believe the answer is E) Input

In a coal-burning power plant, the coal is an example of an Input System. So, the correct option is (E).

What is Coal burning power plant?

Coal-burning power plants are defined as those plants that produce electricity by burning coal in boilers to generate steam. The steam produced under extreme pressure flows into a turbine, which spins a generator to create electricity, then it cools, condenses back into water and returns to the boiler to start the process.

About 50% of coal is used as the primary fuel for power generation. The main function of a coal fired thermal power plant is to convert the energy available in the coal into electricity where as power plants work by using multiple stages to convert the stored energy coal for usable electricity which is an example of input system.

Thus, In a coal-burning power plant, the coal is an example of an Input System. So, the correct option is (E).

Answers

Answer:

The options are

A) electrical energy.

B) mechanical motion.

C) heat and light energy.

D) electrical and heat energy.

The answer is C) heat and light energy.

Explanation:

Chemical energy in the wood is lit up by fire and a burning process begins to occur. Burning involves a substance being consumed by fire and fire aids in the conversion of some forms of energy to mainly light energy as a result of the burning flames and also to heat energy as a result of the high temperature in the form of heat which the fire brings into play.

This validates the stored chemical energy in the logs being changed into light and heat energy.

What type of rock (granitic or basaltic) would be more likely to contain the mineral quartz Why?

Answers

Answer:

I think granitic rock would contain more mineral quartz.

Explanation:

Because the magma cools slowly, crystals of different minerals have time to grow. Molecules in the lava do not have time to arrange themselves to form large crystals. Extrusive rocks have crystals that are too small to see without magnification. A common example of an extrusive igneous rock is basalt.
