Answer: Option A.
It is called specie- area relationship.
Explanation:
Specie- area relationship in ecology describe the relationship between the area or habitat and the total number of species present in the area. It is also called species-area curve.
A larger area will contain a larger number of species.
A lot of factors determine the slope and elevation of specie-area relationship and they are, immigration and extinction rate, predator- prey dynamics, rate of disturbances between large and small area e.t.c.
for self pollination, pollen grains are transferred to the stigma of another plant on the same species while on cross pollination is transferred to the stigma of another plant on a different species of plant.
Cyanobacterial species are thought to be the first photosynthetic organisms. These unicellular bacteria occur in Maine environments, the presence of water acted as a sun-screen, preventing the denaturation of photosynthetic hardware by exposure to high uv. This high volume of Cyanobacteria in the oceans produced vast quantities of oxygen - this allowed organisms to grow in size a their metabolic demands could now be met. At one point the large concentrations of oxygen lead to gigantism. following the first endosymbiotic event, where a cyanobacterial cell became enslaved in a bacterial cell, photosynthetic eukaryotes were 'born'. This lead to the formation of both terrestrial and marine chloroxygenic organisms.
Answer:
Golgi apparatus
Explanation:
The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, several types of vacuoles, and the plasma membrane.
The Golgi apparatus consists of flattened membranous sacs called cisternae. They are stacked upon each other. The membrane of each cisterna in a stack maintains the unique internal space from the cytosol. Proteins and lipids formed on the ER are packed in many transport vesicles and are delivered to the Golgi apparatus.
The Golgi apparatus serves as a site for modification, and packaging of proteins and lipids. Modification of proteins in the Golgi apparatus results in the formation of several types of modified biomolecules such as glycoproteins. It serves as the site for the packaging of secreted proteins and sorting of other proteins to vacuoles and other organelles via transport vesicles. The transport vesicles carrying various biomolecules are formed in the trans face of the Golgi apparatus. These vesicles pinch off from the Golgi membrane and transport their contents to a specific destination.
In this case, brown frogs increase and green frogs decrease, whereas natural selection would cause this change in allele frequency.
<h3>What is natural selection?</h3>
Natural selection is the main evolutionary force by which populations change (evolve) across time.
Natural selection leads to the change in the allele frequencies depending on the more adapted phenotypes in a given environment.
In conclusion, brown frogs increase and green frogs decrease, whereas Natural selection would cause this change in allele frequency.
