Can hydrogen peroxide be broken down by catalysts other than those found in a living system? What is/are the control(s) and why are they needed?
Answer:
Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down
Explanation:
because it contains no catalytic properties
Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.
What is a catalyst?A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.
Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).
The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.
Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.
As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.
Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature.
Why is it important the blood is constantly moving?
Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.
Explanation:
Why are differences and similarities in DNA and proteins evidence of evolution?
Answer:

Question: how the distance from a plate boundary affects the earthquake
Answer:
The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source.
Explanation:
So the if the strength of the shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.
Answer:
lol , ok so the strength and the shacking of the earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.

Explanation:
tiustltstsrllsuustrsylrsyrylylsslslylttllysslyslylysr
Answer:
precipitation
Explanation:
Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.
Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

What do you think would happen if cells were not able to replicate and divide
Answer:
theyed eventually become extinct because they are unable to reproduce
Answer:
Each cell has an identical set of DNA (chromosomes), and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer, which causes cell division to happen too fast.

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques
Answer:
is created from careful research and logical reasoning
is able to be tested using validated techniques
Explanation:
A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.
