Creo que es  D) grass, antelope, lion

Explanation:

El antílope se alimenta de hierba y el león del antílope.

In an ecosystem, the correct order for the food chain is grass, antelope, lion.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.

Matter cannot be created destroyed

Explanation

Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Answer:

A.

The sound is transmitted through water until it reaches the other whale.

Explanation:

When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.

The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.

The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.

In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.

It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.

Therefore, the correct option for this question is A.

Answer:

D. 4 protons 2 neutrons and 4 electrons

Answer:

At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.

Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.

On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.

Explanation:

Mercury in the periodic table is Hg, and bromine is Br

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

Answer:

Temperatures decrease with increasing height as the ozone layer is left behind and the air thins out with increasing altitude. The lowest portion of the low-pressure mesosphere is heated by the warm air of the upper stratosphere. This heat radiates upward, getting less intense as altitude increases.

Explanation:

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

Answer:

A is the correct answer

Explanation:

Moon pulls the ocean upwards causing tides

The position of a coastal area during a low tide is: it is on a side of Earth that is perpendicular to the Moon.

Whenever the absolute bottom, or the box, arrives at a coast, the coast encounters a low tide. Envision the sea is molded like a ball pointing at the moon. The football's sharp closures address the pieces of the Earth encountering elevated tide and the ball's level sides are the pieces of the earth encountering low tide.

Thus, option A is correct.

Answer:

The water supply is not safe.

Explanation:

Ionically, the reaction is;

Pb^2+(aq) + 2Br^-(aq) -------> PbBr2(s)

Amount of Br^- reacted = 2/1000 * 0.12 = 2.4 * 10^-4 moles

From the reaction equation;

1 mole of Pb^2+ requires 2 moles of Br^- for complete precipitation

x moles of Pb^2+ requires 2.4 * 10^-4 moles of Br^-

x = 1 * 2.4 * 10^-4 /2

x = 1.2 * 10^-4 moles of Pb^2+

Concentration of Pb^2+ precipitated from 5ml of tap water =  1.2 * 10^-4 * 1000/5

Concentration = 2.4 * 10^-2 M

The amount of  Pb^2+ found in the water is greater than the maximum allowable concentration of Pb2+ ions in water in a local community which is 1.51 x 10-8 M. Therefore, the water supply is not safe.
