changed. The mass has." How would you respond? Write your response in your
Science Journal.
Answer:
Explanation:
Both would be right if some of the clay was removed.
Since there is no mention of anything being removed, both are incorrect. There is always the same mass when the shape has been altered.
What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

Aside from solar energy, what else could provide electrons?
Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature.
Small charged particles called electrons, which normally flow via a wire, provide electrical energy. An illustration of electrical energy in nature is lightning.
What are the different sources of electron?The majority of free electrons are created with minimal kinetic energy and just disperse through the atmosphere, participating in the random thermal motion of every atom.
With enough kinetic energy, some free electrons are created that can lead to further ionization and excitation.
The source of electrons is a filament, or cathode. Usually, it is a tungsten wire in the form of a hairpin.
The surrounding cathode cap is given an accelerating voltage (determined quantity of negative high voltage). The filament is then exposed to a tiny emission current to liberate electrons.
Therefore, aside from solar energy, electron are produce.

In one sentence explain why carbon dioxide is considered the most important greenhouse gas, although it traps much less heat than other greenhouse gases such as methane, nitrous oxide and CFCs.
Answer:
Because plants need carbon dioxide more than any other compound/element. Also, heat doesn't make much of a difference in a plants growth or production. It's sunlight that makes a difference.
Carbon dioxide is considered as the most important greenhouse gas due to its abundancy in the atmosphere.
• In the atmosphere, climate change is mainly an issue due to high concentration of carbon dioxide in the atmosphere.
• This overload is because of the burning of fossil fuels and burning of forests.
• Apart from carbon dioxide there are many heat trapping gases like water vapor and methane, however, carbon dioxide is putting us at greater threat due to irreversible modifications it takes place if it continues to gather at such rate in the atmosphere.
• Carbon dioxide has contributed more to climate change than any other greenhouse gases between 1750 and 2011.
• The other gases like methane possess more potent heat trapping tendency per molecule in comparison to carbon dioxide, however, they are far less in comparison to carbon dioxide in the atmosphere.
• The tendency of carbon dioxide to remain in the atmosphere for longer durations in comparison to other heat trapping gases makes it the most potent greenhouse gas.
Thus, the abundancy of carbon dioxide in the atmosphere makes it the most powerful greenhouse gas in comparison to other greenhouse gases.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this: 6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
The question is incomplete, the complete question is;
In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2
cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
See explanation
Explanation:
If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.
Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.
After the enzyme and substrate bind together and perform the reaction, what does the substrate become?
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.
After the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.
Enzymes are biological catalysts that bind specific substrates to speed up the rate of a given chemical reaction. Substrates are molecules upon which the enzymes act.Products are molecules formed from chemical reactions.Enzymes function by lowering the energy of activation of different chemical reactions.In conclusion, after the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.

During an earthquake, energy that has built up in the earth's crust is released by waves traveling through which type of medium?
the ground
the water
a vacuum
the air
During an earthquake, the energy that has built up in the earth's crust is released by waves traveling through the ground. Thus, the correct option for this question is A.
What is an Earthquake?An earthquake may be defined as a process that significantly involves the sudden trembling of the surface of the earth that is typically produced by the immediate movement of rock materials below the earth's surface.
According to the context of this question, the tectonic plates are continuously moving, but sometimes they got stuck at their edges due to friction. This stimulates the stress on the edge that overcomes the friction.
This is the reason which facilitates the action of an earthquake that significantly liberates energy in waves that travel through the earth's crust and provokes the trembling that we suddenly feel.
Therefore, during an earthquake, the energy that has built up in the earth's crust is released by waves traveling through the ground. Thus, the correct option for this question is A.

Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Essential amino acids are available to the body through diet.
What are amino acids?Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.
Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.
There are twenty different amino acids present. Amino acids are classified into four main groups:
Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acidsAmino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.
Amino acids are joined together in large number and form polypetides through peptide bond formation.
Based on the nutritional requirements amino acids are classified into two types:
Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.
