Which statement best explains the importance of enzymes lowering the activation energy necessary for reactions to take place?
a Reactions that require less energy to begin are able to occur more quickly.
b Reactions produce heat, causing the chemical bonds to become strong.
c Reactions are able to proceed slowly to maintain the metabolism of the cells.
d Reactions requiring less energy are able to produce less product.
Answer:
A
Explanation:
because a enzyme simply speeds up a reaction and only does that by pressure and stress not by doing chemical changes
The statement which best explains the importance of enzymes lowering the activation energy necessary for chemical reactions to take place is: A. Reactions that require less energy to begin are able to occur more quickly.
A chemical reaction can be defined as a chemical process which mainly involves the continuous transformation or rearrangement of the ionic, atomic or molecular structure of a chemical element through a break down and formation of chemical bonds, in order to produce a new chemical compound.
As a general rule, the activation energy of a chemical reaction must first of all be reached by its combining chemical elements (reactants) before it can start or begin.
An enzyme can be defined as a biological catalyst that is used to speed up (increase) or catalyze (accelerate) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).
Hence, a chemical reaction that only require less energy to begin (start) are able to occur more quickly before those that require high energy.
In conclusion, the activation energy of a chemical reaction should be lowered in order for it to occur or take place fast (quickly) enough over a short period of time.

What is a mixture in which all the components are evenly spread out?
Answer:
A mixture is made when two or more substances are combined, but they are not combined chemically. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

Which is an appropriate conclusion for the data shown?
The decrease in carbon dioxide (CO2) for the leaf was less than the decrease for the stem.
- More oxygen was produced in the stem than in the leaf.
-There was no photosynthesis taking place in the roots.
- The stem was performing photosynthesis at a faster rate than the leaf.
Answer: I think Its the stem was performing photosynthesis at a faster rate than the leaf. But I'm not 100% sure, but I think its that one. I hope this helped!

Lava is rock that has undergone a physical change and has liquefied. What is known about this change?
The lava gained mass.
The lava was burned into smoke.
The lava can cool back into rock.
The lava lost mass.
Answer:
The lava can cool back into a rock
Explanation:
Physical changes can be reversed. Hence, the lava can cool back into rock.
What are physical changes?Physical changes are changes that happen to the physical properties of materials only. They are usually reversible when subjected to appropriate conditions.
In this case, the lava rock changed from a solid to a liquid as a result of melting at high a temperature. Once the liquefied rock is cooled, it will return back to being solid.

Explanation:
The Devils Hole pupfish is one of the world's rarest fishes, spending most of its life in the top few meters of very warm waters of a cavern located in the middle of the Mojave Desert. Devils Hole,
a geologic pool, is the only naturally occurring habitat for the endangered Devils Hole pupfish. This fish's habitat is one of the smallest natural ranges known for any vertebrate. Devils Hole is an
extreme environment, with water temperatures and dissolved oxygen concentrations near the lethal limits for most fish species.
Which of the following statements best explains why the Devils Hole pupfish are able to live in this environment?
Answer:
Thermal invasive
Explanation:
Devils Hole pupfish can live in this environment because they have adapted genes, which offer resistance to their bodies to the harsh environment where they live.
We can come to this answer because:
A living being can only live in an inhospitable environment if its organism allows for an adaptation.In this case, we can say that Devils Hole pupfish had a population with different genetic compositions, where some had genes adapted to this environment and others did not have these genes.Devils Hole pupfish that didn't have the adapted genes didn't resist the environment and died.The Devils Hole pupfish that possessed the genes survived and passed those genes on to their descendants.In this case, Devils Hole pupfish that received the genes adapted to the environment developed resistance that allows them to live amidst extreme resources.

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.
