A chemical change occurs when both the physical properties of a substance and its identity change. The correct option is C.
What are chemical changes?A chemical change is a change when the identity of a substance changes, and it converts into a new substance with new characteristics and a new identity.
When iron comes in contact with oxygen, it changes into rust, and it is a chemical change. A chemical change is a transformation in which the substance's chemical composition is altered through atom rearrangement. Atomic alterations cause changes in the molecular structure.
Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.
Therefore, the correct option is C. both the physical properties of a substance and its identity change.

scientific explanation of how a trait like less pigmentation became common in populations that live far from the equator
Answer:
selection favored lighter skin
Explanation:
This delicate balancing act explains why the peoples that migrated to colder geographic zones with less sunlight developed lighter skin color. As people moved to areas farther from the equator with lower UV levels, natural selection favored lighter skin which allowed UV rays to penetrate and produce essential vitamin D.

What role do the proteins in a virus’s outer coat play in the invasion of a host cell?
Answer:
They fit the proteins on the surface of the host cell.
Explanation:
The proteins in a virus's outer coat play a significant role in the attachment with the host cells and invade the host body.
What do you mean by Virus?A Virus may be defined as a microorganism that infects cells and may cause diseases.
The outer coat of the virus consists majorly of spike proteins that attach to the host cells and enter the body through the process of endocytosis.
Therefore, the proteins in a virus's outer coat play a significant role in the attachment with the host cells and invade the host body.

Explanation:
The movement of materials from the plasma membrane, through endosomes, and then to lysosomes describes which type of pathway?.
Answer:
Below
Explanation:
The routes that lead inward from the cell surface to lysosomes start with the process of endocytosis, by which cells take up macromolecules, particulate substances, and, in specialized cases, even other cells. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed. One type is called phagocytosis (“cellular eating”), which involves the ingestion of large particles, such as microorganisms or dead cells via large vesicles called phagosomes (generally >250 nm in diameter). The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.
Are mirror neurons the scientific explanation for empathy?
Answer:
Mirror neurons respond both when perceiving an action and while executing an action. They provide a direct internal experience of another person's actions or emotions and may be the neurological basis of empathy.
Explanation:
Mirror neurons respond to perceiving an action while executing an action. They provide a direct internal experience of action or emotion of another person and are the neurological basis of empathy.
What are mirror neurons?Mirror neurons are a category of neurons that modulate activity both when an individual executes a specific motor act and also when they observe a similar act performed by another individual.
Mirror neurons activate when for example when monkeys break peanuts when they see others doing the same even in darkness as they hear peanuts being broken.

b.
It is not essential to life.
c.
It does not occur naturally.
d.
It does not involve the atmosphere.
Answer:
The cycle only involves the lithosphere, hydrosphere, and biosphere, with no role in the atmosphere. The reason the atmosphere is not involved in that at the natural temperature and pressure of the environment, phosphorus and its compounds are usually in solid or ionic (usually phosphate ion) form. It is also a very slow nutrient cycle, with a major source of the nutrient being determined by tectonic activity that upwells the nutrients from deep in their earth’s core through volcanic activity.
