Water-borne diseases such as cholera typhoid hepatitis B etc. spread by drinking contaminated water. These water-borne diseases can be prevented by ensuring proper disposal of sewage excreta periodic cleaning. Also measures such as disinfecting community water reservoirs boiling drinking water etc. should be observed.
For bacterial growth in a cell culture, growth law is very similar to the law of radioactive decay. Which of the following graphs is most suitable to represent bacterial colony growth? Where \( N \)
- Number of Bacteria at any time, \( N_0 \)
- Initial number of Bacteria.
List I | List II | ||
---|---|---|---|
A | Exophthalmic goiter | I | Excess secretion of cortisol, moon face & hypergylcemia |
B | Acromegaly | II | Hypo-secretion of thyroid hormone and stunted growth. |
C | Cushing’s syndrome | III | Hyper secretion of thyroid hormone & protruding eye balls. |
D | Cretinism | IV | Excessive secretion of growth hormone. |
A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
Given below is a heterogeneous RNA formed during Eukaryotic transcription:
How many introns and exons respectively are present in the hnRNA?
A certain reaction is 50 complete in 20 minutes at 300 K and the same reaction is 50 complete in 5 minutes at 350 K. Calculate the activation energy if it is a first order reaction. Given: \[ R = 8.314 \, \text{J K}^{-1} \, \text{mol}^{-1}, \quad \log 4 = 0.602 \]
Any adverse variation from an organism's normal structural or functional condition is usually associated with specific signs and symptoms and distinct from physical injury.
A few diseases appear out of nowhere and persist only a few days. Acute diseases, such as the common cold, are examples of them. Acute diseases frequently become chronic if they are not treated.
Acute diseases include strep throat, fractured bones, appendicitis, influenza, pneumonia, and others.
Acute diseases develop quickly and are accompanied by unique symptoms that necessitate immediate or short-term treatment and improve once treated. Acute illnesses, such as the common cold, can sometimes go away on their own.
Chronic diseases are illnesses that develop over time and endure for a long time or even a lifetime. Chronic disease is defined as a disease that lasts more than three years. The symptoms are relatively modest at first.
