number of plants vs. number of animals
number and variety of organisms vs. changing environment
number of organisms vs. constant environment
The right answer is number and variety of organisms vs. changing environment
Global warming therefore involves a transformation of the environment that results in the disappearance and the appearance of certain habitats and, more generally, by the displacement of the geographical area that hosts the habitats required for a species. So some animals are forced to move to a more adequate climate, otherwise they will not survive.
Ecosystems are complex and constantly changing systems where multiple factors interact. The answer that best indicates the dynamic balance of an ecosystem is b. number and variety of organisms vs. changing environment.
The number and variety of organisms within an ecosystem and their ability to adapt and thrive in response to a changing environment indicate a dynamic balance. In a healthy ecosystem, there is a diverse array of species, each occupying specific niches and interacting with other organisms and the environment in various ways.
As the environment changes, such as through natural disturbances or climate fluctuations, the dynamic balance of the ecosystem is maintained by the resilience and adaptability of the organisms within it. This balance involves continuous adjustments and interactions among species, ensuring the overall stability and functionality of the ecosystem.
Therefore, the answer that best indicates the dynamic balance of an ecosystem is b. number and variety of organisms vs. changing environment.

Homo sapien
Homo
sapien
Answer: Homo sapien is a scientific species designation.
Homo sapien is a scientific designation for modern human species. The name to Homo sapien was given by the father of modern biological classification, Carolus Linnaeus in 1758. Homo is the genus to which human belongs and sapien means the only surviving species of the genus Homo.
In scientific nomenclature, a species is designated by a two-part name, which includes the genus and species name. 'Homo sapien' is the correct answer.
In scientific nomenclature, a species is uniquely designated by a two-part name: the genus name and the species name. Within the options provided, Homo sapien is the correct scientific species designation. 'Homo' is the genus, which includes humans and our closest extinct relatives, and 'sapien' denotes our specific species within the genus Homo. Thus, a combination of both terms - Homo sapien - correctly designates the human species.

Phospholipids form a bilayer in water because of the shape and amphipathic nature of the lipid molecules
Phospholipids are a class of lipids, it are a major component of all cell membranes. Phospholipids are the shape and amphipathic nature of the lipid molecules that cause them to form bilayers spontaneously in aqueous environments. The most abundant membrane lipids are the phospholipids.
Phospholipids form a bilayer in water because of the shape and amphipathic nature of the lipid molecules. Phospholipids shape are cylindrical and the phospholipid molecules spontaneously form bilayers in aqueous environments. All of the lipid molecules in cell membranes are amphipathic. Amphipatic is the condition where phospholipids have a hydrophilic (water-loving) or polar end and a hydrophobic (water-fearing) or nonpolar end. The structure of the phospholipid molecule consists of two hydrophobic fatty acid "tails" and a hydrophilic "head". Phospholipids arrange themselves into two parallel layers called a phospholipid bilayer. The lipid bilayer or phospholipid bilayer is a thin polar membrane which is made of two layers of lipid molecules. This layer makes up the cell membranes and is critical to the ability of cell's function.

Phospholipids form a bilayer in water due to their amphipathic nature, with hydrophilic heads facing out and hydrophobic tails facing each other. This lipid bilayer acts as a barrier in the plasma membrane, separating materials on either side. Structures such as micelles, liposomes, and lipid-bilayer sheets are formed by phospholipids in water.
Phospholipids form a bilayer in water because of their amphipathic nature. The polar heads of phospholipids are attracted to water molecules, while the nonpolar tails are not. This leads to the arrangement of phospholipids with their hydrophobic tails facing each other and their hydrophilic heads facing out, resulting in the formation of a lipid bilayer.
This bilayer structure is essential for the plasma membrane as it acts as a barrier, separating the water and other materials on one side of the membrane from the water and other materials on the other side.
Examples of structures formed by phospholipids in water are micelles, liposomes, and lipid-bilayer sheets, which are the structural basis for cell membranes and various subcellular components.

The porins are the membrane proteins, which allows the transfer of the molecules. It is a transport protein. The cipro-resistance protein is also a transport protein. Both the porins and the cipro resistance proteins are membrane transport protein. The presence of the cipro-resistance protein does not allow the ciproflaxin drug molecule to cross through the normal protein, as a result it causes resistance.
