Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion, a process of passive transport that moves these gases down their concentration gradient. Certain other substances rely on facilitated transport, another type of passive transport, to cross the membrane.
Oxygen and carbon dioxide pass through the plasma membrane by simple diffusion. The structure of the lipid bilayer, composed of hydrophobic phospholipids, allows small, uncharged molecules such as oxygen and carbon dioxide to diffuse down their concentration gradient. This process is a form of passive transport, meaning it doesn't require energy input from the cell.
When there is a higher concentration of oxygen or carbon dioxide outside the cell than inside, these gases will naturally diffuse across the membrane, moving from an area of higher concentration to an area of lower concentration. The same concept applies when there's a higher concentration of these gases inside the cell; they will diffuse out of the cell into the extracellular fluid where their concentration is lower.
Also note that some polar substances and other molecules that do not easily pass through the membrane rely on facilitated transport. This is another type of passive transport where specific integral proteins or glycoprotein receptors on the cell membrane help these substances cross the membrane down their concentration gradient.

Explanation:
2. the largest taxonomic category
3. the categories used in classifying organisms
4. a taxonomic category containing a group of similar genera
A. taxon
B. taxonomy
C. family
D. domain
In other words, we can also say that taxon is also known as a taxonomic group of any rank, such as a species, family, or class. It is a group of one or more than one different populations of an organism or the organisms viewed by taxonomists to make a system. These are the rules for naming new animals.
A taxonomy is said to be a scheme of classification or in other words, we can also define the term taxonomy as the branch of science involved with classification, especially of organisms, systematics. Organisms are grouped together. This science of gives name, describe and classify the organisms including all the plants, animals and the microorganisms of the world.
Family is the one that has been classified between order and genus. A family is also divided into the subfamilies. It is one of the eight main and important taxonomic levels. It is a primary taxonomic category of organisms ranking. This category comes on the sixth number of all the categories lies in a taxonomic group.
In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.
2) organisms that sexually select
3) organisms with average traits
4) organisms with extreme traits
The organisms with extreme traits.
• Diversifying selection also known as disruptive selection, illustrates variations in population genetics in which extreme traits are favored over the intermediate traits.
• It is the rarest of the three kinds of natural selection and can result in the deviation of a species line.
• In disruptive selection, the makeup of the population would demonstrate phenotypes of both extremes traits.
• One of the most common example of disruptive selection is London's peppered moths. The darker colored moths were able to survive from predators as they blended with the polluted surroundings, while the lighter moths got extinct. The medium-colored moths were witnessed easily and got killed by the predators.
Thus, correct answer is option 4, that is, organisms with extreme traits.

In certain populations disruptive selection is occurring in this population which is most likely to survive

Answer:
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
