What is the definition of cell specialization


specialization
The specialization leads to a better adaptation to specific environmental conditions in living beings through changes in the structure or through the development of certain behavior patterns.

specializationen
In most habitats, the existing biomass of the living animals is always greater than that of the (relatively fresh) dead. It follows that relatively few vertebrate species specialize in carrion as an obligatory source of food.

specialization on goods that can be produced cheaply
Increase in total production - welfare gain
international division of labor - Adam Smith
Theory of comparative cost advantages - D. Riccardo ...

The ~ of the body cells happens according to a cell-internal program, so the process is genetically undepigenetically determined. However, environmental influences can also leave traces in the genome of a living being in the form of epigenetic changes. Identical twins are a good example of this.

The ~ In many cases, a certain food is largely dependent on its availability, so that seasonally polyphagous animals can be temporary food specialists. The choice of certain nutrients is often mediated by smells and flavors.
Examples [edit] ...

Through the ~ Different food sources can lead to species segregation.
Mutant that is better adapted to a certain temperature
First we explain the term mutant to you so that you can understand this possibility of sympatric speciation without any problems: ...

- Along with found one ~ different population groups on certain activities instead. Now there were shepherds who looked after the flocks or farmers who tilled the fields. Spiritual and political leaderships such as priests and tribal chiefs also established themselves.

few cells become more efficient in terms of sensory perception
larger pigment spots (larger, stronger flagella?) → differentiation and ~
this is at the expense of the ability to regenerate
Cells lose their ability to divide ...

Sports exercises, ~, general exercises
Competitive sports (competitive centers, clubs with competitive sports departments)
top sporting performance ...

In contrast to omnivory, polyphagia expresses a wide range of food sources, but still a certain degree of ~ underlying.

- a minimum number of species should be given - creation of a food web and material cycles - not too many species, this would also be a high degree ~cause ...
Does biodiversity have a social value?

The height ~ leads to the fact that mountain passes represent insurmountable obstacles for some organisms.

No area of ​​application of biology has a greater need for biologists from a wide range of disciplines ~sgrade. For example, biologists check

In the course of evolution one began ~ of cells. In this way, cells specialized in producing and releasing enzymes that break down the fat, protein and carbohydrate molecules in food into smaller molecules. The absorption of these smaller molecules into the metabolic cycle is done by other cells.

FALSE The innumerable dead ends of evolution - mainly due to narrow (sometimes extreme) ~ - make you think of a bungler rather than an intelligent planner. Why should it have allowed 99 percent of all species that have ever existed to be extinct again?

Offspring leaves a stronger one in plant breeders ~ to, with the animal only
in a few areas (animals with a large number of offspring: chickens, superovulation in cattle).
The eradicated breeding animals are used as farm animals, whereas eradicated plants are used
mostly discarded.

Describes the structural and functional ~ of cells and cell tissues during the development of an organism. For example, nerve, muscle and gland cells differentiate from unspecialized embryonic stem cells of an embryo.

-by function changes or -~ mergers and reductions may have taken place, so the relative position of the organs or structures in a comparable structural system is decisive

... and divide after the ~process is completed, then sometimes not for months or years, or even not at all.
Facts About Mitosis
Even red blood cells (erythrocytes) cannot divide because they do not have a nucleus.

According to this model, the eukaryotic cell has become through ~ inner membranes evolved, which go back to prokaryotic plasma membranes.
Autoimmune disease
An immunological disorder in which the immune system turns against its own body.

1. Explain terms: a) Differentiation b) Centralization c) ~ 2. What is the significance of the development of the blood circulation for the energy balance? Hope you can help me! Would be really nice, thank you!

The term caste refers to a group of individuals who perform certain tasks and who are determined for this purpose ~have trained (physique, behavior). Boxes in this sense are z. B.

Which trend, however, will be the stronger: degeneration or ~ will only show itself in the next few million years.

The differentiation in construction improves certain performances of the cell and is with one ~ linked to certain tasks. Differentiated cells are no longer totipotent. You still have all the information, but you can no longer access it all.

Definition: Adaptive Radiation describes the fanning out of a species into several subspecies with different ones ~s are better suited for certain biotopes.

The constant struggle for survival, the advantages of better adapted hunting or defense characteristics and the resulting selection advantage often lead to ~en: ...

The keeping of sheep can vary depending on ~ be designed for meat, milk or wool. For example, some sheep species give significantly more milk than others, but their fur is slow to grow.
Worldwide, the number of sheep kept is estimated at around 1.2 billion.

The genes that give them this ~ They pass them on to the next generation, and finally, after many thousands of generations, a completely new species has formed that can no longer interbreed with the competing species.

"Theories of evolution that only support the survival of the adapted, its optimization and ~s are not only incomplete, they also lack the essentials. Because: Without "arrival of the fittest" there is also no "survival of the fittest".
