Answer: A)They generate electricity by contact

Explanation: triboelectricity can be simply defined as a phenomenon where static electricity is produced when two different materials are vigorously and continuously rubbed or come in contact with each other. This vigorous and continous contact allow electrons to jump from one material (atom) to another there by creating static electricity.

This characteristics is evident when an individual walks across a carpet while wearing a wool socks, as the wool and the carpet vigorously and continuously rub against one another, electrons are transfered from the carpet to the socks which spread all over the surface of the body. (The body becomes negativity charged while the carpet becomes positively charged) This is why the individual will feel a shock sensation when he or she goes on to touch the door knob due to the static electricity generated.

Final answer:

Walking across a carpet in wool socks and accumulating an electric charge exemplifies the characteristic that electrical forces can exert a force across a distance. This is reflected in the creation of an electric field that influences other objects without direct contact. (option C)

Explanation:

Walking across a carpet in wool socks and creating an electric charge is evidence of electric fields generated by the accumulation of static electricity due to friction, and this static charge can exert a force across a distance.

This is because electric charges produce electric fields that influence other charges, even when they are not in direct contact. Therefore, the observation supports the characteristic that electrical forces can exert a force across a distance, which corresponds to option C) They can exert a force across a distance.

Furthermore, the act of walking across the carpet and subsequently experiencing a spark upon touching a metal object is an example of charging by contact. The electrons transferred through friction between the socks and the carpet create an excess of negative charge on your body.

When this charge finds a path to equalize—as in touching a doorknob—a spark is observed due to the rapid movement of electrons to the neutral object.

The DNA component that makes up the genetic code is nitrogenous bases. The correct option is C.

Nucleobases, also known as nitrogenous bases or simply bases, are nitrogen-containing biological compounds that form nucleosides.

These are then components of nucleotides, all of which are the basic building blocks of nucleic acids.

A combination of five nitrogenous bases is employed to build nucleotides namely adenine, guanine, cytosine, thymine (found only in DNA) and uracil (found only in RNA).

This in turn build nucleic acids including certain DNA as well as RNA. These bases are critical because their sequencing in DNA and RNA is how information is stored.

Nitrogenous bases are the DNA components that make up the genetic code.

Thus, the correct option is C.

Option C, where the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, would most likely result in the extinction of the reptile species over a period of twenty thousand years.

Explanation:

The most likely scenario that would result in the extinction of the reptile species over a period of twenty thousand years is option C. This is because if the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, the species will not have the ability to adapt to the new environment and may struggle to find enough food to survive.

Without the ability to adapt and thrive in the changing vegetation, the reptile species would likely face extinction over time.

Answer: there are many types such as animal and plant cells and you can see it in their components.

Explanation:

Cells differ from one another due to specialization and differentiation, where each cell type expresses only certain genes relevant to its function despite all of them having the same DNA. This allows for a variety of cell types with unique functions necessary for an organism's survival.

All cells are not the same because they undergo specialization and differentiation. Just as actors read only their parts from a movie script, every cell in a multicellular organism contains the same DNA but only "reads" the part that is necessary for its unique function. This is the fundamental concept behind why a muscle cell, a liver cell, and a skin cell look and act differently, despite having an identical genetic blueprint. This specialized gene expression allows cells with the same DNA to become different cell types, enabling the diverse functions necessary for organismal development and survival.

For example, epithelial cells provide protection, bone cells support structure, immune system cells fight pathogens, and red blood cells transport oxygen. These variations among cells are essential for the growth, development, and maintenance of the body. Even unicellular organisms exhibit gene regulation in response to environmental changes, highlighting the importance of gene expression in cell function and diversity.

The change in the population of peppered moths from primarily light-colored to predominantly dark-colored during the industrial revolution demonstrates directional selection, where a shift occurs towards a phenotype that provides a survival advantage in changing environments.

Explanation:

The phenomenon described with the population of peppered moths (Biston betularia) during the industrial revolution is an example of directional selection. As the industrial revolution caused the death of the light-colored lichens on trees, darker moths had a survival advantage because their coloration provided better camouflage against a sooty environment. Overtime, the percentage of dark moths increased dramatically from 1% to 90%, indicating a shift in the population's phenotype towards those better suited for their environment. This change in the color of the moth population from light to dark constitutes directional selection, where one extreme phenotype is favored over others causing a shift in the population's genetic variation over time.

Answer: The correct answer is from areas of high concentration to low concentration.

Explanation: Diffusion, by definition, is the process of molecules (any molecule) going down their concentration gradient (i.e. they are going from higher concentration to lower concentration). Hope that helped!

When molecules diffuse across the cell membrane, molecules move from areas of high concentration to low concentration.

In facilitated diffusion, molecules diffuse across the plasma membrane with the help of membrane proteins such as channels and carrier proteins. The concentration gradient of these molecules exists, so they have the potential to diffuse into (or out of) the cell.

With this information, we can conclude that when molecules diffuse across the cell membrane, molecules move from areas of high concentration to low concentration.
