How does matter change during a chemical reaction?
Answer:
During a chemical reaction, what happens to matter? An atom is regrouped or rearranged during a chemical reaction. During chemical reactions, two or more chemical bonds are formed or broken, not atoms
Explanation:
A chemical change produces a new substance, while a physical change does not. Reactions involving chemical elements involve combining them. New, different chemical and physical properties result from the chemical reaction. The chemical reaction cannot destroy or create matter. A new substance is formed when particles of one substance are rearranged.

Hope this Helps
Organisms can be separated by their most basic characteristics into the broadest groups known as Kingdoms.
What are kingdoms?It is a taxonomic group composed of smaller groups called phyla. The classification of living organisms into kingdoms is a way of organizing the diversity of life into manageable categories.
The most widely recognized system of classification is the Five kingdom classification which was given by Robert Whittaker which recognizes kingdoms such as- Monera, Protista, Fungi, Plantae and Animalia.
Each kingdom is further divided into smaller groups based on increasingly specific characteristics until the species level is reached. The system of classification is constantly being refined with the discovery and interrelationship between different organisms.

If a human wanted to have the most efficient absorption of energy, what trophic level would they want to eat from?
If a human wanted to have the most efficient absorption of energy, they want to eat from the first trophic level.
What is meant by Trophic level?The Trophic level may be characterized as an organism occupying a specific place in the food chain that runs in an ecosystem. It determines the exact location of each and every organism on the basis of its mode of nutrition.
As we all know that the first trophic level is generally tenanted by the plants which are producers. These organisms directly captured sunlight and derive their food. They are also known as Producers.
According to the 10% law given by Lindeman, only 10% of energy gets successfully transmitted into the next trophic level. So, the first trophic level delivers the most efficient absorption of energy to humans.
Therefore, if a human wanted to have the most efficient absorption of energy, they want to eat from the first trophic level.

The part of the neuron directs the manufacture of substances that help the neuron grow in the cell body. The correct option is b.
What are neurons?The cell body, dendrites, and axon are the three components that make up a neuron. The majority of the molecules that the neuron requires to survive and operate are produced in the nucleus, which is part of the cell body.
The chromosomes, which make up the genetic makeup of the cell, are located inside the nucleus. The nucleus regulates protein synthesis through these chromosomes, as well as cell growth and differentiation into its final form.
The neurotrophins serve as axon guidance molecules, encourage synaptogenesis, and support the growth and survival of neurons.
Therefore, the correct option is b, cell body.

Which statement best describes a political consequence of sustainable waste management?
Industries are responsible for improper waste clean-up.
Incinerators release fewer emissions into the atmosphere.
Transporting waste to other countries saves land for housing.
Ecosystems are saved when less land is used for landfills.
The statement that best describes the political consequence of sustainable waste management is that industries are responsible for improper waste clean-up.
When referring to political consequences we are referring to the possible effects of a situation on the public view of the entity. What this means is that if a corporation takes a certain action, there will be political consequences, which can be good or bad. To offer some examples:
Good: A company that makes cereal optimizes its production to create fewer emissions, as a consequence, more people buy this cereal because they know it is better for the environment.Bad: A company dumps its toxic waste into the nearby river, as a consequence, the community protests and boycotts the company.The statement that Industries are responsible for improper waste clean-up is an example of a political consequence, this statement corresponds perfectly to the example given of a bad political consequence. It can also cause good consequences in that if the Industry properly disposes of their waste, they may be viewed more favorably in the public eye.

where will the water go?
A)equally in and out - equilibrium
B)into the cell
C)out of the cell
Answer:
c) out of the cell
Explanation:
The process of osmosis is the diffusion of water across a membrane. It is crucial for organisms to balance water between themselves and their surroundings.
Since this cell is placed in a solvent containing more solutes than inside the cell, the cell is considered to be in a hypertonic solution, and thus will expel water out.
plant leaves contain openings called stomata, which allow the diffusion of _______.
Answer:
plant leaves contain openings called stomata, which allow the diffusion of gas exchange
Plant leaves contain openings called stomata, which allow the diffusion of gases.
WHAT ROLE DOES STOMATA PLAY?Plants are living organisms that obtain carbon dioxide (CO2) gas from the atmosphere and give off oxygen gas in the process of photosynthesis.
They contain a structure that opens and closes on their leaves called stomata. This stomata functions as a means of gaseous exchange between the plant and the environment.
Therefore, plant leaves contain openings called stomata, which allow the diffusion of gases.

Explanation:
17% of energy is used for agriculture...
how? plants need sunlight to do photosynthesis and maybe if only 17% of is used for agriculture people might get low product.. and they should atleast apply 50 to 60 percent so that more plants can do more photosynthesis and thus, they will get more products.
