Our body comes in contact with millions of disease-causing pathogens throughout the day. But still, we are not ill or infected all the time. The credit for this goes to our immune mechanism i.e., our immunity. We have two sorts of immunity-Innate and Acquired. Both of them are very essential for the healthy survival and well-being of an individual. But they widely differ in their appearance and working mechanism. The most significant difference between them is their time of … [Read more...]

Cytokinesis and karyokinesis are significant steps in the cell cycle. The term 'Cyto' refers to the cytoplasm, and 'kinesis' refers to the movement. Cytokinesis is the process involving the division of the cytoplasm of a cell. On the other side, the word 'Karyon' means nucleus, and 'kinesis' is movement. Thus, karyokinesis depicts the nuclear division or the segregation of nuclear material. Cytokinesis is comparatively a simpler and single-step process. In comparison, karyokinesis involves a … [Read more...]

The sympathetic & parasympathetic nervous systems are two components of the autonomic nervous system. These are responsible for controlling and manipulating our involuntary actions. We can differentiate SNS and PNS depending on their responsibilities and action potential. The SNS mobilises the body in stressful situations such as danger, sports, and fights. Thus, it triggers a “fight or flight” response. The PNS helps to produce and preserve the body’s normal homeostasis. Thus, it … [Read more...]

The population of any region is characterised with respect to its growth rate. Exponential and Logistic growth models are two typical but important growth models that can be used to track the population's growth rate. Exponential growth is characterised by the rapid expansion of the population that is unaffected by any upper limit. Contrarily, logistic growth refers to a sustainable growth rate that has an upper limit of growth. The exponential growth model depicts an indefinite growth … [Read more...]
