How are producers and consumers related?
A. Both producers and consumers can be animals.
B. Both producers and consumers make their own food.
C. Both producers and consumers use energy that started from the sun.
D. Both producers and consumers are plants.
Answer:
It C
Explanation: Because consumers the producers and the producers get their energy from the Sun so that means that consumers are getting all their food from things that start that with the Sun.
The distribution of energy and nutrients through the ecosystem is defined as the food chain. The producers and consumers are the members of food chain. The correct option is C.
What are producers and consumers?The organisms which can produce food by themselves from simple inorganic substances like water, sunlight, carbon dioxide are defined as producers. Examples are green plants and algae.
The consumers are the organisms which consume the food prepared by producers. Examples are human beings and cows. The consumers are dependent on the producers for energy and food.
The producers prepare food through the process photosynthesis. They are the main source of energy for other trophic levels. The producers have autotrophic mode of nutrition.
The consumers have heterotrophic mode of nutrition. They have to eat to gain energy otherwise they will die.
Thus the correct option is C - Both producers and consumers use energy that started from the sun.

A flexible container at an initial volume of 6.13 L contains 2.51 mol of gas. More gas is then added to the container until it reaches a final volume of 11.3 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
Answer:
2.12 moles of gas were added.
Explanation:
We can solve this problem by using Avogadro's law, which states that at constant temperature and pressure:
V₁n₂=V₂n₁Where in this case:
V₁ = 6.13 Ln₂ = ?V₂ = 11.3 Ln₁ = 2.51 molWe input the data:
6.13 L * n₂ = 11.3 L * 2.51 moln₂ = 4.63As 4.63 moles is the final number of moles, the number of moles added is:
4.63 - 2.51 = 2.12 molesPlease only answer if you're going to help.

What is the study of matter and energy and how do they interact?
Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity - just about anything, honestly. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entire galaxies.
What are energy and its relation to matter?
The mass of these three particles is less than the mass of a neutron, so they each get some energy as well. So energy and matter are really the same things. Completely interchangeable. And finally, Although energy and mass are related through special relativity, mass and space are related through general relativity.

True or false: chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals
Answer:
False
Explanation:
The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.
This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).
An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.

EXPLAIN :This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls. They don't corrode and they can be bent to fit around corners.
Copper is a ductile metal due to ductility.This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls.
Ductility is a mechanical property commonly described as a material's amenability to drawing (e.g. into wire).In materials science, ductility is defined by the degree to which a material can sustain plastic deformation under tensile stress before failure. Ductility is an important consideration in engineering and manufacturing. It defines a material's suitability for certain manufacturing operations (such as cold working) and its capacity to absorb mechanical overload.
Some metals that are generally described as ductile include gold and copper, while platinum is the most ductile of all metals in pure form.However, not all metals experience ductile failure as some can be characterized with brittle failure like cast iron. Polymers generally can be viewed as ductile materials as they typically allow for plastic deformation.

Dry air is 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide so varying amounts of water vapor- depending on humidity. Some gases however strongly absorb infrared radiation and trap it in the atmosphere and can therefore result in elevated global temperatures. Therefore they are termed greenhouse gases. Which greenhouse gas have we observed a marked increase in atmospheric concentrations in the last 100 years?
A. methane (CH4)
B. carbon monoxide
C. carbon dioxide
D.ozone (03)
E. oxygen
F. nitrogen
G.water vapor (H20)
Answer:
C. Carbon dioxide
Explanation:
Carbon dioxide is one of the end-product of combustion reactions involving many fuels today.
With the rapid increase in urbanization and technological development, man demand for energy increased tremendously. The discovery of fossil fuels paved the way for the astronomical increase in the concentration of carbon dioxide in the atmosphere. The burning of fossil fuels like coal and oil invovles the process where the carbon atoms present in these fuels combine with oxygen in the air to make CO2. This has resulted in an increase in the concentration of atmospheric carbon dioxide (CO2).
The burning fossil fuels for electricity, industry, heat, and transportation are the major sources of the emossion of carbon dioxide.
Also, the cutting down of trees for paper production, building construction and for the establishment of settlements also increase the concentration of carbon dioxide in the atmosphere. Trees are help remove carbon dioxide from the atmosphere through the process of photosynthesis. However, when these trees are cut down, carbon dioxide accumulates in the atmosphere.

This is the original color of the Statue of Liberty gifted to the United States by
France. It's very different from the way it looks today. Describe why it has
changed and possible causes.?
Answer:
The Statue of Liberty represents Libertas, the Roman Goddess of Liberty. She is holding a torch and a tablet with the date of the US Declaration of Independence. She is dressed in a robe, wears a crown, and has a broken chain at her feet. The Statue of Liberty was a gift from France to the United States. It was designed by the sculptor Frederic Auguste Bartholdi and built by Gustave Eiffel in 1886. The US designed and paid for the granite and concrete foundation .Over the next three decades, the statue slowly began to change color. Currently, the Statue of Liberty is green in color. How did this happen? The air and water reacted with the copper metal and resulted in oxidation. This oxidation created a layer of patina, a copper carbonate. This does not harm the statue and actually helps to protect the copper sheets below.

Answer:
during the Revolutionary War, France became a close friend of Americans seeking freedom from Great Britain. To honor its friendship with America, France gave the U.S. a special gift: sculptor Frederic-Auguste Bartholdi's beautiful statue called Liberty Enlightening the World.
The Statue of Liberty arrived in New York Harbor on June 19, 1885. It came in 350 pieces packed into 214 crates. The statue was assembled on a pedestal base built by the United States. The 151-foot tall statue has become a worldwide symbol of freedom and democracy.
The Statue of Liberty's home is Bedloe's Island (renamed Liberty Island in 1956). From 1892 to 1943, “Lady Liberty" greeted over 12 million immigrants as they arrived on boats at the nearby Ellis Island Immigration Station.
