Explanation:In order to combine substances to create a specific material, Ella needs to know the properties of the substances she is working with. This includes understanding the composition of the substances, their chemical and physical properties, and how they interact with each other. By knowing these factors, Ella can choose appropriate substances and determine the correct ratios or conditions for combining them to achieve the desired material.
For example, if Ella wants to create a strong and durable polymer, she would need to know the properties of the different monomers she can use as building blocks. This includes information on their molecular structure, reactivity, and compatibility with other monomers. Ella would also need to consider the reaction conditions, such as temperature and pressure, that could affect the polymerization process.
Overall, having a solid understanding of the properties and behavior of the substances being combined is essential for Ella to successfully create a specific material.

Final answer:
Before combining substances to form a new material, Ella should identify the elements involved, understand their properties, and learn the stoichiometry required for the reaction. She must also understand the molecular-level characteristics that lead to certain properties, states of matter, energy changes, and how resistivity and other physical properties emerge from atom and molecule interactions. Research on how materials behave under different conditions is essential for effective use of the new material.
Explanation:
Ella is interested in combining substances to form a new material. Before Ella combines the substances to create a specific material, she needs to understand certain fundamental aspects of Chemistry. Firstly, Ella should identify the elements that make up the substances and understand their chemical properties. This knowledge will be crucial when predicting how the elements might interact with each other.
Next, it is important for Ella to learn the stoichiometry of the reaction, which involves the calculation of the amount of one substance that will react with or be produced from a given amount of another substance. This will help her in determining the correct proportions of each substance for the reaction to obtain the desired material.
Understanding the physical and chemical properties of the material at the molecular-level is also important. This would mean researching the desired properties of the material and what molecular-level characteristics lead to those properties. For example, resistivity is a property that could be important depending on the use of the new material.
Additionally, Ella should understand the states of matter, energy changes during substance combinations as well as the interactions of atoms and molecules which result in macroscopic properties of materials, as outlined in the materials' resistivity and electric and magnetic properties. Knowledge of how different conditions, such as temperature or pressure, affect the behavior of materials is crucial for employing the new material effectively.
Ella should conduct an activity to classify materials around her and try to understand why these materials were chosen based on their properties, as this process of classification by properties could guide her in creating the new material. This understanding stems from polymer chemistry, which often requires probing how materials behave under different conditions.
Finally, if the new material is complex, such as a fluid mixture or a crystal of layered material like graphite, understanding its specifications in terms of number of molecules and their arrangement is necessary to determine its complete set of properties, including energy.

Explanation:
which of the following are examples of a negative feedback loops? A. global warming B. a thermostat that controls the heat in your home C. Loss of bioriversity D. fruit ripening E. convection currents F. I dont know yet
Answer:
C and A
Explanation:
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
The following are the examples of negative feedback loops:
A. global warming
C. Loss of biodiversity
A negative feedback loop is also called as an inhibitory loop. It is a kind of self-regulating system.It inhibits the future production of output by the system. For example, the body reduces manufacturing of some proteins or hormones when their level is too high. A thermostat that controls heat, ripening of fruit, and convectional currents are not the examples of a negative feedback loops. Global warming is the increase in the green house gases into the atmosphere. Carbon dioxide is one of green house gases. The level of carbon dioxide in the atmosphere can be controlled by the absorption of carbon dioxide gas from the atmosphere by the plants. This process is self regulating. But if plants are removed by deforestation then it will increase the global warming. Loss of biodiversity can inhibit the future production of output of the system that is the total number of species that will reduce in future.Hence, A. global warming, and C. Loss of biodiversity are the correct options.

what are the plates that make up Earths crust
Answer:
The Tectonic plates.
Explanation:
Answer: The tectonic plates
Explanation:
It is probably within the reach of human technology to make the climate of Mars inhabitable. It might be several centuries before people could live there, even with breathing apparatuses, but some of the world’s great temples and cathedrals took centuries to build. Research efforts now are justified if there is even a chance of making another planet inhabitable. Besides, the intellectual exercise of understanding how the Martian atmosphere might be changed could help in understanding atmospheric changes inadvertently triggered by human activity on Earth.The main point of the argument is that:_____________
A. It is probably technologically possible for humankind to alter the climate of Mars.
B. It would take several centuries to make Mars even marginally inhabitable.
C. Making Mars inhabitable is an effort comparable to building a great temple or cathedral.
D. Research efforts aimed at discovering how to change the climate of Mars are justified.
E. Efforts to change the climate of Mars could facilitate understanding of the Earth’s climate.
Answer:
A, It is probably technologically possible for humankind to alter the climate of Mars.
Explanation:
It is said within the first sentence that "it is probably within the reach of human technology to make the climate of Mars inhabitable". This claim is most similar to answer choice A.
The topics brought up in the other answer choices are not even mentioned in this excerpt, meaning they can't be the main idea.
Final answer:
The main point of the argument is that the research into terraforming Mars is justified because it could provide valuable insights into Earth's own atmospheric challenges.

PLEASE HELPPPP!!!!!!!!!!!!Which statement is TRUE about northern geography and its impacts?
A.The climate mekes farming difficult in New England
B.Very few trees grow in the Great Plains due to the cold
C.The most northerly States have the longest growing season
D.States in the north experience only two different seasons
Answer:
c
Explanation:
The correct statement about northern geography and its impacts is A: The climate makes farming difficult in New England. This is a true reflection of the challenges faced by the region due to its climate.
The North is one of the least densely populated regions in North America, characterized by brutally cold winters, short growing seasons, and poor soil quality. These factors make farming particularly challenging in places like New England. The statement that the most northerly states have the longest growing seasons is incorrect due to the extreme cold and long winters, which significantly shorten the growing period for crops. Additionally, the Great Plains, contrary to the assertion that very few trees grow there due to the cold, actually have a different natural vegetation profile, with tree growth not being primarily limited by temperature. As for the North experiencing only two seasons, this is also incorrect as the northern states experience four distinct seasons, although winter may be significantly longer and harsher than in other regions.

Which boundary or zone adds new material to the lithosphere
Answer:
The answer is Divergent plate boundary.
Explanation:
Under the rising convection current of magma, the plates move apart from each other causing crack. The uprising magma would then fill the crack and cools down to form new plate material which adds to the lithosphere.
Divergent plate boundary adds new material to the lithosphere. The plates separate from one another under the rising magma's convection circulation, forming a fracture. Once the fracture has been filled with rising magma and has cooled, new plate material is formed, adding to the lithosphere.
What is a Divergent plate boundary?A diverging boundary, also known as a divergent plate boundary, in plate tectonics is a linear structure that exists between two tectonic plates that are moving apart. Rifts are originally created by divergent borders inside continents, and they gradually develop into rift valleys. According to recent studies, material rises to the lithosphere's base beneath each divergent plate boundary due to complicated convection in the Earth's mantle.
Large flood basalt or lava flows are created as a result of the asthenosphere's (or upper mantle's) rock being melted and the pressure in the area being reduced. Tectonic plates may drift hundreds of kilometers away from one another over the course of millions of years.
