The conditions of the environment don’t always remain constant. Instead it is always changing. Thus the organisms that live on different environments have to find suitable ways to adapt to the changes in the environment and ensure their survival.
By bringing changes in their behaviour organisms try to adapt to environmental changes. Migration is an example of behavioural change. When the conditions of the living environment change, making it a place difficult to thrive upon, organisms temporarily migrate from the area to more comfortable regions.
Summer and winter sleep habits of several organisms are also examples of behavioural adaptation.
Serious systemic fungal infections and parasitic infections usually only develop in individuals who are immunocompromised. These individuals have a weak immune system. The body cannot respond quickly to infections since their immunity is not very well developed.
The step of the cellular respiration pathway that can take place in the absence of O2 is glycolysis, glycolysis is an anaerobic that’s mean it’s does not require oxygen O2
Microtubules play an important role in cell division by contributing to the formation of the mitotic spindle, which plays a part in the migration of duplicated chromosomes during anaphase.
