The process of natural selection is described in the cartoon.
Explanation:
Natural selection is the mechanism by which an organism survive and evolve.
It is the process in which organism have better adaptation to its environment and live to reproduce organisms with useful traits which are passed on to their offsprings.
In the given cartoon it is observed that green beatles fall prey to the crows as a result their survival chances are minimal. Over the generations they are eaten by crows and eventually their brown counterparts are in majority. This is because the brown colour beatles are safe from the prey, they pass on this trait to their offspring and remains safe and more in population.
The brown colouration in beatles is the Darwinian trait of survival of the fittest for beatles.
The variation in population, mutation or genetic drift causes natural selection.
The one with better adaptation survives and reproduce more viable offspring in the population.
A: provided structural support to the cell
Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
Yes they do they have skin lay over there fat to keep warm.
