Which gland secretes odorous secretion in mammals:
- Bartholins
- Prostate
- Anal gland
- Liver-bile
The Correct Option is C
Solution and Explanation
The gland that secretes odorous secretion in mammals is the Anal gland. Anal glands, also known as anal sacs, are found near the anus and contain a foul-smelling secretion that can be used for scent marking, communication, and defense in some mammals.
So, the correct option is (C): Anal gland

Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:

Chemical Coordination and Integration - Hormones
Hormones are chemical messengers that are released directly into the bloodstream, where they are carried to organs and tissues throughout the body to perform their tasks. Hormones are released by the body's endocrine glands.
Functions of Hormones
Following are some important functions of hormones:
- Food metabolism.
- Growth and development.
- Controlling thirst and hunger.
- Maintaining body temperature.
- Regulating mood and cognitive functions.
- Initiating and maintaining sexual development and reproduction.
Types of Hormones
To regulate various functions, different types of hormones are produced in the body. They are classified as follows:
- Peptide Hormones: Peptide hormones are composed of amino acids and are soluble in water.
- Steroid Hormones: Unlike peptide hormones, steroid hormones are fat-soluble and are able to pass through a cell membrane.

- Estrogen
- Melatonin
- Progesterone
- Testosterone
