module 1
Module 1:
1.
Anton van Leeuwenhoek made an
essential contribution to the development of the cell theory. Elaborate his
contribution to the scientific community. click here
2.
The tree of life was produced by comparing
Genetic Sequence Data, and can you make a tree of life with the domain of
bacteria, archaea, and eukarya.click here
3.
Water is denser as a liquid than as a
solid. Can you explain why and how?
4.
Can simple molecules and kinetic
energy lead to chemical evolution? Elaborate what experiment supports this
hypothesis and infer your results for the same.
5.
The prebiotic soup model of chemical
evolution is a well-accepted model for the development of life on earth. Do you
agree with this hypothesis? If it is yes, justify your answer.
6.
When H2 and CO2
react, acetic acid can be formed spontaneously while the production of
formaldehyde requires an input of energy. What do you infer from this reaction
and justify your answer?
7.
The flounder is able to survive in
very cold water, but only when water is in its liquid state. Discuss what
properties of water in the solid state may prevent or harm life.
8.
The genomes of a wide array of
extremophiles have been sequenced, and expeditions regularly seek to
characterize new species. Why?
9.
Robert Koch postulates a link between
a particular species of bacterium and a specific disease. Can you narrate his
postulates to understand how the disease is transmitting to the living system?
10.
What makes some bacterial cells
pathogenic but not probiotic organisms that live in our gastrointestinal tract?
11.
You have studied extremophiles as
part of your Biology. What are they, and can you give one example of such
extremophiles and mention their usage in research.
12.
Discuss morphological diversity of
the bacteria with sufficient examples.
13.
Gram staining differentiates
Gram-negative bacteria from Gram-positive bacteria, how they are carried out in
the laboratory, and discuss the mechanism of action of the stain.
14.
Elaborate the life cycle of one
protists who starts life in a mosquito and matures in humans with a colorful
diagram.
15.
Algal blooms are significant events
in lakes or seas; what kinds of organisms cause these blooms and their impact
on the environment.
16.
Discuss the evolution of mitochondria
and chloroplast as part of the cell, and What morphological innovations evolved
in protists?
17.
You and your friends go to a seaside
resort as part of a fun trip where you indulge in various delicious seafood.
The next day all of you fall sick. You think this is due to seafood allergy,
but diagnosis reveals that you all were poisoned. What could be the reason for
poisoning due to seafood consumption? Discuss in detail.
18.
Fungi-like saprophytes are efficient
decomposers. They carry out extracellular digestion i.e. breaking complex
molecules like starch or cellulose into simple sugars for assimilation outside
the cell. Design a simple experiment to visualize this phenomenon of digestion.
19.
In ecological prospective what determines
the distribution and abundance of organisms?
20.
Discuss in detail the evolutionary
thought related to the natural selection process.
21.
Levels of homology exist in all
living organisms and discuss in detail with different kinds of homology exist
with suitable examples.
22.
What is Multidrug-resistant tuberculosis,
and how did Mycobacterium tuberculosis become resistant to antibiotics?
23.
Explain why the over-prescription of
antibiotics by doctors, or the overuse of everyday soaps containing
antibiotics, can be a health risk.
