Which one of the following is an example of a cell type found only in a single phylum?
Show Hint
- Cnidocyte
- Erythrocyte
- Myocyte
- Neurocyte
The Correct Option is A
Solution and Explanation
Step 1: Understanding Cnidocytes.
Cnidocytes are specialized cells found only in the phylum Cnidaria, which includes organisms like jellyfish, corals, and sea anemones. These cells contain a stinger (nematocyst) used for defense and capturing prey.
Step 2: Explanation of the other options.
Erythrocytes (red blood cells) are found in all vertebrates.
Myocytes (muscle cells) are found across many phyla, not limited to a single one.
Neurocytes (nerve cells) are also widespread across multiple animal phyla.

Questions Asked in GATE EY exam
- An organization allows its employees to work independently on consultancy projects but charges an overhead on the consulting fee.
The overhead is 20% of the consulting fee if the fee is up to ₹5,00,000.
For higher fees, the overhead is ₹1,00,000 plus 10% of the amount by which the fee exceeds ₹5,00,000.
The government charges a Goods and Services Tax (GST) of 18% on the total amount (i.e., the consulting fee plus the overhead).
An employee of the organization charges this entire amount — that is, the consulting fee, overhead, and tax — to the client.
If the client cannot pay more than ₹10,00,000, what is the maximum consulting fee that the employee can charge?

After the 1st round, the 4th student behind P leaves the game.
After the 2nd round, the 5th student behind Q leaves the game.
After the 3rd round, the 3rd student behind V leaves the game.
After the 4th round, the 4th student behind U leaves the game.
Who all are left in the game after the 4th round?
A stick of length one meter is broken at two locations at distances of \( b_1 \) and \( b_2 \) from the origin (0), as shown in the figure. Note that \( 0<b_1<b_2<1 \). Which one of the following is NOT a necessary condition for forming a triangle using the three pieces?
Note: All lengths are in meter. The figure shown is representative.
- Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
P: Over time, such adaptations lead to significant evolutionary changes with the potential to shape the development of new species.
Q: In natural world, organisms constantly adapt to their environments in response to challenges and opportunities.
R: This process of adaptation is driven by the principle of natural selection, where favorable traits increase an organism’s chances of survival and reproduction.
S: As environments change, organisms that can adapt their behavior, structure, and physiology to such changes are more likely to survive.
