Questions · 💫 Germination of spore · Exosporium:

A thin delicate outermost covering of the spore

Spore Coat:

2nd layer underneath the exosporium. It is thick and composed of several protein layers. Resistant to chemicals It contains enzymes for germination. Germination of spores into vegetative form occurs when the environment becomes favorable for their growth.

Cortex:

It is the 3rd layer from outside in. It has peptidoglycan in it.

Spore Cell Wall or Core Wall

Surrounds the protoplast or spore core

Spore Core:

Contains nucleoid and ribosomes

💫 Epidemiology and it's methods

The study of where and when diseases occur and how they are transmitted in a population

Descriptive Epidemiology

It includes location and time of cases of disease, gender, health, age of patients etc. (Basically, frequency and distribution of risk factors in population are recorded).

Analytical Epidemiology:

It relates to determining the cause of the disease. Analysis of data, mode of transmission of diseases and means to prevent diseases also come in this discipline. Such studies can be done with case control methods in which factors that have preceded the disease are determined.
