The process of evolutionary changes that result in formation of new species and groups of species is called speciation .
What are evolutionary change?Evolutionary change are defined as the gradual heritable alteration of populations and species brought on by processes including sexual selection, random genetic drift, and natural selection. A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
Through speciation, a new plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique traits. The process by which new species emerge is known as speciation. Groups in a species experience it when they grow reproductively separated and diverge.
Thus, the process of evolutionary changes that result in formation of new species and groups of species is called speciation .

Place the following digestive tract structures in the order they would be encountered by an ingested food molecule:
The placement of digestive tract structures in the order they would be encountered by an ingested food molecule would be Pharynx, Esophagus, Stomach, Duodenum, Jejunum, Ileum, Cecum, Ascending colon, Transverse colon and Descending colon.
The pharynx is the part of respiratory system which carries air, food and fluid down from the nose and mouth. It connects to the esophagus, which is a long tube like structure that ends in the stomach. Stomach is a muscular bag like structure where food is broken down and passed into intestine as small pieces. The main role of the duodenum is to complete the first phase of digestion. The primary function of the jejunum and ileum is to absorb sugars, amino acids, and fatty acids. Cecum is the fermentation chamber. The colon has the function of reabsorption of water and some nutrients and electrolytes from partially digested food and removal of waste.

which statement describes the way in which phosphorylation directly contributes to signal transduction?
Proteins can connect with new binding partners thanks to phosphorylation, which modifies the structure of the protein.
Phosphorylation sites are created by protein kinases (also known as "writers"), frequently have an impact after being recognized by phospho-binding proteins (also known as "readers"), and are afterwards eliminated by protein phosphatases (also known as "erasers").
This writer-reader-eraser toolbox has been crucial in the evolution of new functionalities necessary for the development of multicellular organisms and enables phosphorylation events to control a wide range of regulatory activities. Typically modular in organization, the proteins that make up this system of protein kinases, phospho-binding targets, and phosphatases are made up of several globular domains and smaller peptide motifs having binding or catalytic capabilities.
Through genetic recombination, the linking of these binding and catalytic modules in novel ways, as well as the choice of certain domain combinations, have aided in the emergence of new, physiologically advantageous processes. Conversely,

A brand-new species, perhaps based on a distinct food supply or physical characteristic. Three different gene types—habitat preference genes, assortative mating genes, and habitat-based fitness genes—have been hypothesized to support sympatric speciation. Sympatric speciation is the theory that some animals and plants diverged while coexisting. A common ancestor of several cichlid species lived in Lake Tanganyika in Africa.

the flow of highly energetic electrons through the electron transport chain changes the of the pump proteins, which causes them to transport protons across the membrane.
The flow of the highly energetic electrons through electron transport chain will change the shape of the pump.
As the high-energy electrons are transported along the chain, some of their energy is trapped. This energy is used to drive hydrogen ions (from NADH and FADH2) from the matrix across the inner membrane and into the intermembrane space.
In the electron transport chain, electrons are passed from one molecule to another and the energy released in these electron transfers is used to form an electrochemical gradient.
Chemiosmosis uses the energy stored in the gradient to produce ATP. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom.
Therefore, the flow of highly energetic electrons through the electron transport chain changes the Electron transport chain of the pump proteins, which causes them to transport protons across the membrane.

The question of whether cells are bigger in larger mammals than in smaller ones — think of an elephant's liver cell compared with a liver cell from a mouse — is usually answered by saying that larger mammals don't typically have bigger cells, they just have more of them.
Animals can vary enormously in size, but they're alike in at least one way. The individual cells that compose all of their bodies--from shrews to people to dinosaurs--are roughly the same size. Big animals just have many more cells than little animals.
Cell is the basic unit of life. Yes, the cells of ant and elephant are same. All organisms are made up of cells and they are of different sizes and shapes. Size of cell does not make any difference between the ant and elephant but its the number of cells which makes such differences in their body sizes.
