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.

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?
Smooth ice reduces the inertia of the hockey puck.
Smooth ice increases the force used to accelerate the hockey puck.
Smooth ice reduces the unbalanced forces that would slow the hockey puck.
Smooth ice decreases the reaction force that the ice exerts on the hockey puck.
It is important to keep the ice smooth on a hockey rink because this reduces the unbalanced forces that would slow the hockey puck.
Frictional forcesFrictional forces are opposing forces to the motion of an object on a platform.
In order to be able to pass a puck as quickly as possible on a hockey rink, there should be a minimal frictional force on the ice surface on which the puck moves.
With minimal opposing forces, the puck will move as unhindered as possible and passing as fast as possible would be easy.

Explanation:
The mitochondria is known as the “powerhouse of the cell." Why?*
glucose is broken down into cellular energy (ATP).
lipids release energy as they form polypeptide bonds.
glucose is created through the process of photosynthesis.
proteins create energy as they are converted from sugars.
Answer:
The correct answer is - glucose is broken down into cellular energy (ATP).
Explanation:
Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.
The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.
Thus, the prower house of the cell is mitochondria.

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.

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.

(Picture included) The student investigated the movement of water through plants. The plants were covered with clear plastic to capture any water released into the air. The plants received the same amount of water and sunlight.
Which conclusion is supported by these data?
- Leaves contain cells that store water for respiration.
- Leaves contain cells that control the release of water into the air.
-Leaves contain cells that absorb sunlight and water during photosynthesis.
- Leaves contain cells that stimulate growth by moving water through the plant.
Answer: C -Leaves contain cells that absorb sunlight and water during photosynthesis.
Explanation:
Leaves contain cells that absorb sunlight and water during photosynthesis. That's why after three hours the amount of water decreases as the number of leaves increases. Option (C) is correct.
What are stomata in leaves ?Water is taken up by roots from the soil and moved as a liquid by xylem to the leaves. Small holes in the leaves allow CO2 to enter the leaf for photosynthesis and water to escape as a vapor.
The rate of gas exchange is regulated by stomata, which are pores present in the epidermis of leaves, stems, and other organs. A pair of specialized parenchyma cells called guard cells surrounds the pore, controlling the size of the stomatal opening.
They are essential to photosynthesis because they allow carbon dioxide to enter the leaf and oxygen to leave. Additionally, the stomata aid in transpiration, the process of releasing water vapor through a plant's leaves.
Thus, option (C) is correct about leaves.
