When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. This suggests the liver contains an enzyme that breaks down hydrogen peroxide. Thus, the correct option is C.
Catalase is a common enzyme which is found in nearly all living organisms which are exposed to oxygen gas. Catalase is a key enzyme which uses hydrogen peroxide, a nonradical Reactive Oxygen Species, as its substrate. Catalase enzyme is responsible for the neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell system which is also essential for the cellular signaling processes.
Catalase is an enzyme which causes or speeds up a reaction without being affected during the reaction. The enzyme catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.
Therefore, the correct option is C.

Answer: C
Explanation:
Catalyst is one enzyme from liver that breaks down harmful hydrogen peroxide into oxygen gas and water
Answer:
All plants cells have chlorophyll so there is no problem
O in the chemical bond holding the sugar to the nitrogen base
in the chemical bonds holding the sugar molecule together
O In the chemical bonds holding the phosphate groups together
Energy in ATP is stored in the chemical bonds connecting the phosphate groups. The release of energy occurs when these bonds are broken, specifically between the second and third phosphate groups.
Energy in ATP (Adenosine Triphosphate) is stored in the chemical bonds holding the phosphate groups together. This molecule consists of a nucleoside (adenosine) attached to three phosphate groups. When ATP is broken down into ADP (Adenosine Diphosphate) and inorganic phosphate, a considerable amount of energy is released. This energy release happens due to the breaking of a high-energy bond between the second and third phosphate groups, which are negatively charged and thus naturally repel each other.

• all forests populations
• plants fungi and microbes in the forest
• rushing stream
• rock on which turtles and
frogs sit
please i am really confused and my test is timed so please can someone answer fast :(
Answer:
every squirrel in the forest
all forests populations
plants, fungi and microbes in the forest
Explanation:
In ecology, a community refers to a population of different species of organisms occupying a particular area at a particular time. In other words, community is a group of living organisms of different species interacting with one another in a given habitat.
According to the question, a forest community will contain all plants, animals and microbes in the forest involved in a series of interaction with one another. This includes every squirrel in the forest, all population of organisms in the forest and all plants, fungi and microbes in the forest.
N.B: If the abiotic components are included to the living ones, they will together make up an ECOSYSTEM.
b. false
Answer:
False.
Explanation:
The prokaryotes are smaller in size and has large surface area to volume ratio. This high surface area volume ratio increases the rate of diffusion in case of prokaryotes.
The ratio can be obtained by dividing the surface area to the volume. This signifies that how much surface area is available in comparison the volume of the cell. The large cell has large volume. This means the ratio is inversely proportional to the cell size or volume. Hence, the large cell has small ratio of surface area to volume.
Thus, the correct answer is option (b).
Answer:
Blood always moves through the body by the heart’s pumping action. The muscles in the legs assist blood flow by their action. Aiding these actions, the veins have valves in them that prevent the blood from flowing backward.
Explanation:
Answer:
Blood moves throughout the body because the heart pumps blood
Answer:
In order to lower the temperature.
Explanation:
Mammals and birds uses evaporative cooling due to their high body temperature because this evaporative cooling removes the high temperature from the body. In this process, the water present in the body absorb all the extra heat and remove this extra heat from the body with change its state from liquid to vapors and the body's temperature cools down. This evaporative cooling is occurs in the process of sweating.
Evaporative cooling is an evolution-driven thermal regulation method that certain organisms utilise to cool their bodies. It mainly occurs in organisms living in hot environments like kangaroos.
Evaporative cooling is a biological process related to evolution and is used as a thermal regulatory method by certain organisms. Evaporative cooling occurs when an organism excretes water from its body surface, which then evaporates, absorbing heat and subsequently leading to cooling. This evolutionary adaptation generally occurs in organisms that live in warm or hot environments where they are exposed to high temperatures. An example of an organism using evaporative cooling is the kangaroo, which licks its forearms, allowing the saliva to evaporate and cool its body during intense heat.
